Our EPS Foam is much more durable, lighter, and stronger than traditional Polyurethane foam. Although, the foam is a thermoset, it can still be thermoformed. Foam density is also relative and shouldn’t be used to compare different product types. The table below breaks down PCF ranges for low-, medium-, and high-density polyfoams and memory foams. Density affects foam durability and support. Not all EPS is created equally. What is Superwhite Foam? Beyond its competitive material pricing, EPS - because of its versatility and lightweight characteristics - can offer savings in design and development, product assembly and distribution costs. XPS is another form of a foam which offers improved surface roughness and higher stiffness with reduced thermal conductivity. At frequencies up to 400 MHz, the permittivity is 1.02-1.04 with a loss factor less than 5x10-4 at 1MHz and less than 3x10-5 at 400 MHz. If a product has a 3LB density, that means its 12″ x 12″ x 12″ block weighed 3LB. I'd need to know which foam density is to prefer for building an eps surfboard.

On the surface, it would seem the density or weight of a material would allow you to draw a correlation about its firmness, and vice versa. However, variables such as the grade of raw material used, geometry of the molded part and processing conditions will affect package properties and performance. Once in the mold, the pre puff beads are again steamed to form a block that is anywhere from 37-1/2″ – 54″ x 49″ x 121-1/2″ – 220″. 50% r.h. is 4x1013 ohm-cm. 0000000987 00000 n trailer << /Size 52 /Info 18 0 R /Root 21 0 R /Prev 93118 /ID[<2900b48cfc39341d78a8fe884ee9df4e><2900b48cfc39341d78a8fe884ee9df4e>] >> startxref 0 %%EOF 21 0 obj << /Type /Catalog /Pages 19 0 R >> endobj 50 0 obj << /S 143 /Filter /FlateDecode /Length 51 0 R >> stream – 0; Compressive strength, p.s.i.

Expansion is achieved by virtue of small amounts of gas contained within the polystyrene bead.

When you compare EPS and XPS insulation at the same R-values, EPS insulation can be between 10 to 30 percent less expensive and costs about 19 cents per sq.
