Compared to other rubbers, natural rubber is one of the most flexible types, and it's resistant to water and certain chemicals. It's also resistant to cutting, tearing, wear, fatigue, and abrasion, with a working range between -58 to 212 degrees F. Additionally, it has a lot of tensile strength and adheres easily to other materials.

Foam sealing with FIPFG (Formed-In-Place-Foam-Gasket) technology is significantly more efficient and economical than conventional insert seals (EPDM, TPE, NBR).
