Beschreibung
Zusammenfassung:	The piece has an inner layer and an outer layer formed from a mixture comprising an elastomeric co-polyolefin/a blend of a partially crystalline polyolefin and a synthetic olefin rubber. The outer layer is formed from another mixture comprising homopolyamide. An impact modifier from temperature class of acid-modified ethylene-alpha-olefin copolymers is added to the mixtures, where the homopolyamide comprises a melting point of above 200 degree celsius and average of 8 carbon atoms per monomer unit. The blend of partially crystalline polyolefin and a synthetic olefin rubber is a cross-linked ethylene propylene diene rubber (EPDM)/polypropylene (PP) blend. The mixtures contain additives selected from a group consisting of antioxidants, stabilizers, dyes and soot. The synthetic olefin rubber is selected from a group consisting of santoprene(RTM: not defined).
