FIELD: chemistry.
SUBSTANCE: compositions are meant for making articles with high level of frost resistance and fire resistance - sealants, electric wire holders, cuffs, components of pneumatic, vacuum and hydraulic systems used in different industries. The thermoplastic elastomeric composition contains the following, wt %: fluoropolymer based on vinylidene fluoride - copolymer or mixture of copolymers with fluorine content of 50-70% - 57-70, thermoplastic polyurethane based on ester, 4,4-diphenylmethanediisocyanate and 1,4-butanediol - 24-35 and a copolymer of vinylacetate and polyethylene - the rest. The composition can additionally contain target additives - wollastonite, tetrafluoroethylene in amount of 1-5 wt %.
EFFECT: invention improves processing and elastic properties of the composition, fire resistance and frost resistance.
