Expandable fluorine-contained polymer compositions and foams of fluorine-contained polymer obtained from the compositions

摘要

An expandable fluorine-contained polymer composition comprising (A) a fluorine-contained polymer in which the ratio (tan delta ) of dynamic loss modulus to dynamic storage modulus at a temperature 30 DEG C. higher than the melting point of the polymer ranges from 0.3 to 0.9, and (B) a blowing agent, and a foam obtained from said composition.
