Abstract

Compositions containing fluorinated thermoplastic elastomers with different moelcular weight and with different plastomeric phase/elastomeric phase ratio, essentially formed by: PA1 (a) 30-80% by weight, preferably 50-80%, of a fluorinated thermoplastic elastomer, having a block structure of A-B-A type, wherein A is a plastomeric segment and B is an elastomeric segment; PA1 (b) 10-50% by weight, preferably 20-40% of a fluorinated thermoplastic elastomer having a block structure of A-B-A type; PA1 (c) 0-30% by weight, preferably 0-15%, of a fluorinated plastomer preferably of the same kind as that contained in the component (a) and/or (b).
