EPS Geofoam Interface Coefficient of Friction

Friday, February 23, 2018
Recently, we were asked in an RFI (Request For Information) from a contractor about what friction coefficient they should assume for Geofoam-to-Geofoam interfaces.  The following technical note attempts to provide additional  insight on this topic.

Disclaimer


Like all of our competitors we are familiar with, Cellofoam North America Inc. is an expanded polystyrene (EPS) foam manufacturer and not an engineering consulting firm. Thus, it is beyond our scope as a manufacturer of EPS Geofoam to provide design services on the specific use for our product. Users of our Geofoam should obviously consult with appropriate engineering experts to determine the exact type or specifications of Geofoam required for their project to meet structural and other design requirements as well as jurisdictional building codes. We expect purchasers to use Geofoam in accordance with existing industry standard practices, such as those defined in ASTM D7180, Standard Guide for Use of Expanded Polystyrene (EPS) Geofoam in Geotechnical Projects.1

What is Cellofoam Expanded Polystyrene (EPS) Geofoam?


Cellofoam produces EPS Geofoam in many different types and specifications, manufactured to meet ASTM D6817, Standard Specification for Rigid Cellular Polystyrene Geofoam.2 We produce Geofoam with compressive resistance at one percent strain ranging from approximately 3.6 psi to 18.6 psi.3 Our Geofoam typically comes in block sizes and can easily be cut on-site with hot-wire tooling or saws. We also offer pre-cut taper options to fit your project’s requirements, made to specification. 

EPS Geofoam Applications


Cellofoam’s EPS Geofoam has been used in a very broad range of projects including slope stabilization, highway and road, retaining walls, parking structures, landscaping, pool decks, and cinema seating that require a lightweight structural fill solution. It is ideal for use in commercial building, construction, and roadway applications, due, in part, to its high durability, high compressive strength, and lightweight nature.

A Quick Survey of Published Geofoam-to-Geofoam Friction Coefficients


A number of industry researchers have conducted tests to determine the friction coefficient for EPS Geofoam per ASTM D5321, Standard Test Method for Determining the Coefficient of Friction by the Direct Shear Method.4 A survey of the pertinent literature shows a rather wide range of reported Geofoam-to-Geofoam coefficients of friction.  This is likely primarily due to differences in test specimen dimensions, roughness of the EPS surfaces, moisture, UV exposure, applied normal loads, and other factors.  

One excellent study (Sheeley and Negussey 2000)2 investigated the interface friction between Geofoam and various construction materials, including concrete and geomembranes, as well as Geofoam-to-Geofoam in both wet and dry conditions. Results showed density, sample size, stress level, and surface moisture had no significant impact on Geofoam-to-Geofoam interface strengths. At typical stress levels common with Geofoam applications, the study found Geofoam-to-Geofoam friction coefficients to be generally above 0.7 and 0.9 for residual and peak conditions, respectively.  

Interestingly, Sheeley and Negussey also looked into use of binder plates and revealed them to have questionable performance in enhancing Geofoam-to-Geofoam interface strength. This supports at least one prior study recommending not to use binder plates in normal Geofoam fill applications. Further, they showed while Geofoam-to-concrete interface strength was much higher than that of Geofoam-to-Geofoam, Geofoam-to-geomembranes interface strength was much lower, to the degree that the authors warned that substitution of a concrete load distribution slab with a geomembrane would provide a much weaker interface. 

The EPS Industry Alliance’s report, Expanded Polystyrene (EPS) Geofoam Applications & Technical Data, gives the coefficient of friction of EPS Geofoam of 0.5 along molded or hot wire cut faces, and states it is higher for blocks with roughly (presumably mechanically) cut faces.6 This number appears to be quite conservative, however, as other sources such as the Norwegian Road Research Laboratory reportedly use a coefficient of friction of 0.7 for Geofoam-to-Geofoam and Geofoam-to-subsoil interfaces.7 Further, an extremely thorough overview of Geofoam sponsored by the National Academies, Geofoam Applications in the Design and Construction of Highway Embankments, reports that the range in Geofoam-to-Geofoam coefficients of friction found in the literature is 0.5 - 0.7, while 0.64 is “the value reported in the most extensive and detailed published study to date...” 8

EPS Geofoam Friction Coefficient: The Bottom Line


The bottom line is that, based on the above - and other - industry test results, while some researchers recommend designers assume a coefficient of friction of 0.6 for a Geofoam-to-Geofoam interface, the jury is still out on what this number should be. Ultimately, however, it is the responsibility of the project engineer to make this determination and use EPS Geofoam in accordance with existing industry standard practices, such as those defined in ASTM D7180.

Role of Temperature Controlled Packaging in Pharmaceuticals

Tuesday, September 20, 2016
The pharmaceutical and medicine business is a booming, billion dollar industry that relies on cutting edge science, high technology machinery, and research from some of the sharpest minds around the globe. Many times, the final link to successful execution relies on the shipping industry and, in some instances, cold chain shipping solutions and temperature controlled packaging, to ensure that products arrive  on time and in good condition.

Cold Chain Shipping and Pharmaceuticals


Cold chain shipping is vital for the pharmaceutical and biochemical industry. Without it, many medications that are temperature-sensitive would not reach their destination unspoiled and in good health. Patients would need to turn to other alternative (if they existed) for their medicine needs and some medical advances would not even be possible.

Take a medication such as insulin for example. Diabetics rely on it to help control their blood sugars. Many forms of insulin require refrigeration before - and after - delivery. Changes in temperature can spoil the product or lessen its effectiveness. Without proper packaging, this medication would not arrive in usable condition to the pharmacy, much less the patient’s home.

Temperature controlled packaging is important to the research side of the pharmaceutical industry as well. Ingredients and biomaterials, used for the testing and creation of new medicines, often have temperature requirements as well, and so rely on cold chain shipping just as much as the consumer side does.

We have all seen episodes of shows such as E.R. and Grey's Anatomy, where, inevitably, a patient will need an organ transplant and doctors frantically rush to deliver an organ to a needy patient without the temperature falling below or above a certain amount. This is an all too real (if not less dramatic) situation that calls on a specialized form of temperature controlled packaging to keep organs at a constant temperature.

Finally, an often overlooked area of pharmaceuticals that rely on cold chain shipping is the veterinarian world. Medication made specifically for animals has the same concerns as their human counterparts and, again, shipping coolers, gel refrigerants, and insulated coolers all have their place in the packaging needs for veterinarian supplies.

At the end of the day, cold chain shipping means one thing to Big Pharma: getting medical goods from one location to the next without being spoiled, damaged, or ruined. And for that, you need temperature controlled packages!

Benefits of Green Packaging

Thursday, June 30, 2016

Smart business owners are always on the look out for the best packaging and shipping options when it comes to presenting - and delivering - their products. In addition to protection and cushioning. aesthetics and how lightweight a material is, are also important factors. But how about eco-friendliness? What are the advantages of "green packaging?"

Benefits of Green Packaging

In a previous blog post, we discussed some different types of green packaging and looked at what constituted eco-friendly packaging- you can find that blog here: https://cellofoam.com/whatsnew/the-future-of-packaging, Some green packaging materials include recycled content, and expanded polystyrene (EPS) foam packs, wine shippers, etc.

Today we are going to pick up where we left off and chat about the benefits of going green and how using environmentally-friendly packaging can help not just the world, but your company as well.

Lower Costs

Part of the principal behind green packaging is eliminating excess material. In doing so, a company can actually reduce costs associated with packaging (and shipping) over other traditional shipping options. Using custom packaging options, such as custom EPS foam, you can create packs that fit your products without sacrificing on protection or cushioning - in fact, you would be enhancing it, all while saving money.

Brand and Marketing

Another byproduct of eco-friendly packaging is the fact that it is good for your company's image. Consumers and investors alike prefer businesses that practice environmentally friendly techniques, such as energy and green packaging. It shows that a company cares about the world around them and looks at the innovative ways to cut costs - a win-win to the marketplace and Wall Street as well.

Many Options to Choose From

Sustainable packaging comes in a vast array of types, sizes, and materials. Everything from void filler, foam end caps, wine shippers, and cold chain supplies such as temperature controlled packaging for food goods and pharmaceuticals. If there is a shipping product, you can be certain there is an environmentally friendly option for it.

Lightweight

If you choose an option such as expanded polystyrene (EPS) foam packaging. you have the benefit of being eco-friendly, yet highly durable and extremely lightweight, without losing any cushioning or protection. In fact, you will be gaining a higher degree of damage resistance with the addition of this material.

Good for the Environment

This list would not be complete without noting that, above all else, green packaging is good for the environment and the future of our planet. That reason alone makes eco-friendly shipping the right choice -  the other benefits are just icing on the proverbial cake!

If you are in the market for packaging products, give Cellofoam a call and see how our line of wine shippers, EPS foam packaging, custom EPS packaging, and rotational molding can help your business "go green" and "save green" (ie: money) at the same time!

The Future of Packaging

Tuesday, March 22, 2016

There is a lot of news clogging the airwaves these days with regards to the shipping and delivery industry. While a lot of it centers around "neat" ways your pizza will be delivered in the coming years, if you sniff around enough, you will find some more realistic bits of information about just where things may be headed. Robots and drones, you say? But how about for the packaging industry? What does the future of packages look like?

The Future of Packaging

As time passes by, new technology seems to proliferate for any given field; some of these exciting new discoveries stick, while others become a passing fad, casualties of poor marketing, high cost, or too much competition. The packaging industry is not immune to this tumultuous sea of ever-shifting technologies, but there are always mainstays we can rely on and some future packaging options that stand clearly above the rest as contenders for the next generation of innovators.

One trend we see growing year by year is sustainable packaging. Also known as "green packaging" or "eco-friendly packaging", the idea behind sustainable packaging is that the materials you use to ship with meet some - if not all - of the following criteria:
  • Made from recyclable materials
  • Easily recyclable
  • Biodegradable
  • Reusable
  • Are manufactured in an energy efficient manner 
  • Use less natural resources during the manufacturing process
There are many products on the market today that fit the “eco-friendly packaging” billing. Everything from traditional corrugated (cardboard) packaging, to more innovative approaches, such as expanded polystyrene (EPS) foam shippers and recycled tape. Weeding out the best "green" option can sometimes be difficult, but we will leave that for another topic!

An area of growth we see in the packaging industry is the growth of expanded polystyrene (EPS) foam as a packaging material. Made out of plastic beads, EPS offers many advantages over other packaging options: it is lightweight, extremely durable, recyclable, machine moldable (meaning you can create custom packaging), and contains no ozone-depleting chemicals - a win all around the board.

From the food side of the packing business, researchers are pulling out all of the stops as they try to eliminate every piece of wasted material that they can. Some manufacturers have begun to create potato chips bags made entirely of edible material. The idea behind this type of package is that when you are finished with the chips, you can eat the bag - no mess or waste! How you keep the bags clean enough to eat while being stored on a grocery shelf, we are not certain, but it certainly is an interesting concept! Weeding out the best "green" option can sometimes be difficult. We believe, however, the products Cellofoam manufactures satisfy any "eco-friendly" strategy.

White Woven Insulation

WHITE WOVEN SHEATHED INSULATION – POLE BARN CONSTRUCTION

Cellofoam’s WHITE WOVEN SHEATHED INSULATION comes with a white woven polypropylene membrane on Type I EPS core panels providing a superior insulating option for buildings utilizing pole construction design.   There are a number of good reasons for the current interest in pole construction.

  1. In pole construction the poles actually have an inherent ability to resist wind uplift – highly desirable in areas where hurricanes or tornadoes are expected.
  2. A limited amount of grading is required, and no excavation is necessary beyond digging the pole holes.  Thus it can be accomplished with a minimal disturbance of the natural surroundings such as tree roots and top soil.
  3. Pole construction offers a way to lower building costs by utilizing, if desired, step hillside locations which present many problems for more conventional construction. 
  4. No delays in waiting for cement foundations to cure.

Benefits of White woven sheathed insulation include:

  • Specifically engineered hybrid mesh design.
  • High tensile strength.
  • Enhanced flexibility and conforming properties - even on difficult designs.
  • Reliable self-adhesion to eliminate de-bonding.
  • Completely mold and mildew resistant unlike traditional fiberglass insulation.
  • Protects against summer heat gain and winter heat loss!
  • Real savings in construction cost and later in operational efficiency.
  • Equal or better performance in 1/6th or less the thickness.
  • The use of EPS as the insulating material can save up to 150 times the amount of oil and energy used in its manufacture..

Cellofoam’s  WHITE WOVEN SHEATHED INSULATION comes with a reflective metalized membrane on one side and a durable white finished woven polypropylene laminated membrane on the other side. It is easy to wash at high pressure and to maintain. Acid tested, it has a tensile strength of 170 pounds per square inch assuring you a lifetime of use.

Use where you want a clean, washable and durable bright white finish.  Installed on the inside of a large warehouse or agricultural building, the white face may be left as a clean and bright interior finish.    Renovators recognize its advantages and many architects are specifying the material in their designs.
