FLEXIBLE FLUOROCHEMICAL MATERIAL WITH HEAT RESISTANCE AND NONTACKINESS

摘要

To provide the fluorine-containing material which is capable of giving various products, particularly products and parts for OA equipment, is excellent in flexibility, mechanical strength, viscoelasticity and mold-processability and possesses improved non-tackiness. The flexible fluorine-containing material comprises (a) the fluorine-containing multi-segment polymer having the elastomeric fluorine-containing polymer chain segment A and the non-elastomeric fluorine-containing polymer chain segment B in which the elastomeric fluorine-containing polymer chain segment A comprises not less than 90 % by mole of a perhaloolefin unit and (b) the fluorine-containing resin having a crystalline melting point or glass transition temperature of not less than 150 DEG C, in which a weight ratio (a)/(b) is 1/99 to 99/1.
