EPDM Foam—These EPDM foam seals have hollow construction for more compressibility than solid seals. They resist water, sunlight, and ozone. They’re softer and more flexible than EPDM seals and will effortlessly conform to uneven surfaces to shield against dust, noise, and vibration. The foam has closed-cell construction, which resists absorption.

Acrylic Plastic Adhesive—Seals with an acrylic plastic adhesive backing are good for light duty applications where they won’t be jostled or hit frequently. The adhesive has some resistance to water and chemicals.

3M—Seals with a 3M acrylic plastic adhesive backing are more resistant to peeling and shearing than seals with an acrylic adhesive backing. Use them when you need extra sticking strength to resist repeated impact, such as on a door or door frame. They create a permanent moisture barrier and airtight seal between the seal and the surface it’s stuck to, but only if you let the bond cure for 72 hours.
