Williams Everlastic® EJ-2000

The Econ-O-Foam is an expanded, closed-cell, plank, polyethylene foam. It is economical, lightweight, flexible, compressible, resilient, non-absorbent, inherent bond breaker.

Properties & Characteristics
Compressive Strengths

  • Available in a variety of compressive strengths, and can support a wide range of loads.

Weights

  • Available in densities ranging from 1.5 to 2.2 lbs/cu ft.

Chemical Resistance

  • Offers excellent stability when exposed to most acids, hydrocarbons, chlorinated solvents, petroleum products, apints, varnishes, thinners and alcohols.

Temperature Range

  • Has been used successfully in temperatures ranging from -40°F to 160°F without significant effect on its properties.

Water Absorption

  • Virtually impermeable. The amount of water absorbed is negligible even when used in flotation applications. Also offers high resistance to transmission of water vapors, with ratings of less than .1 per inch. It contains no water-soluble constituents.
