About Foam

Light Duty Blended EPDM Foam Sheets and Strips

EPDM is blended with neoprene and SBR to create a general-purpose foam that offers good resistance to water and wear. This foam has closed-cell construction, which restricts water, air, and gases from being absorbed.

Wear-Resistant Natural Gum Foam Sheets and Strips

Because this natural gum foam readily bounces back to shape after compression, it’s a good choice for repetitive sealing applications, such as on doors. These sheets and strips stand up to wear caused by rubbing and scraping. This foam has open-cell construction, which allows water, air, and gases to be absorbed. All have a crisscross texture that provides a nonslip gripping surface.
