Abstract
Composite structures are described that include (a) a first polymer structure (e.g., a film or solid component) made of EPDM adhered to (b) a second polymer structure (film or solid component) that is made of a blend of dynamically vulcanized EPDM dispersed in a matrix of a thermoplastic polyolefin polymer. Either the first polymer structure, or both the first and second polymer structures are blended with an effective amount of a semicrystalline random adhesive copolymer.
Claims14
An elastomeric sealing structure comprising:
- (a) a first polymer structure made of an thermoset EPDM material blended with from 5 to 50 phr of a semicrystalline random copolymer adhered to (b) a second polymer structure made of a blend of a dynamically vulcanized elastomeric material dispersed in a matrix of a thermoplastic polyolefin polymer, wherein said sealing structure is one of extruded profiles or moldings.
