Frequently Asked Questions

What is EPDM rubber used for?

EPDM (Ethylene Propylene Diene Monomer) is a synthetic rubber known for excellent resistance to weather, UV, ozone, and temperature extremes. It's widely used in automotive seals, roofing, and window/door gaskets.

Can you produce custom rubber profiles?

Yes, we specialize in custom rubber extrusions. Provide your design or specifications, and our engineering team will develop the mold and produce samples for approval.

What is the difference between solid and sponge rubber?

Solid rubber is dense and offers high durability and tensile strength. Sponge rubber is cellular (closed-cell), providing excellent compression sealing and flexibility, ideal for weatherstripping.
