EPS Specifications


Raw Material size


The most common billets are 40" x 48" x 16' to 24' long. These Billets are typically cut to smaller more manageable lengths prior to fabricating.





The density is simply how much a 12" x 12" x 12" piece of foam weighs. EPS comes in a variety of densities ranging from 3/4 of a pound to 3 pounds per cubic foot. The most popular density is 1 pound material. The higher the density, the more expensive the foam will be. 



Virgin Material 


EPS is a close cell foam that does not absorb moisture. EPS is cut with hot wires that melt through the foam and seals the cells. Sealing the cells ensures the foam will not absorb moisture. You will always want to buy virgin EPS when you are using it for a floatation application. You should also use virgin material on any application that involves adhesives or coatings. Lastly, buying virgin EPS is your best option if you require a smooth and accurate cut.



Recycled Grind Material


Grind is simply EPS scrap that is grounded and torn into small chunks. These chunks are mixed with virgin material to create a new billet that has recycled content. Billets with grind can be produced with a significant percentage of recycled material. 


This does lower your price and you are able to use a reclaim product. On the other hand, the more grind you add the easier the foam breaks. Each chunk of grind contains multiple cells that are torn open from the grinding process. Open cells absorb moisture and moisture can rule out many applications. Cutting EPS that has grind will result in a rough, bumpy surface that requires larger tolerances.


However, depending on your project, grind could be the perfect option for you, and it will give you a cheaper price.
