Abstract:
1. Thermoplastic elastomer composition consisting of: a thermoplastic polyolefin, a dynamically vulcanized elastomer consisting of monomer units of ethylene, an α-olefin and optionally one or more non-conjugated polyenes and oil, 0.5 to 3.0 parts per 100 parts of elastomer of a phenolic resin vulcanizing agent, and optionally at least one additive selected from the group consisting of fillers, antioxidants, stabilizers, antistatic agents, lubricants, foaming agents, pigments and flame retardants, wherein the composition has an oil/elastomer ratio of at least 2.1/1 and a content of thermoplastic polyolefin of less than 10 wt % relative to the total weight of the thermoplastic elastomer composition, and a hardness of below 35 Shore A at a delay time of 15 seconds, and wherein granulate of the composition is capable of flowing out of a cylinder, held in vertical position, within 120 seconds, after being kept in the cylinder under a pressure of 465 kg/m
