Expandable fluorine-containing polymer compositions, and foams of fluorine-containing polymer obtained from the compositions.

摘要

An expandable fluorine-contained polymer composition comprising (A) a fluorine-contained polymer in which the ratio (tan δ) of dynamic loss modulus to dynamic storage modulus at a temperature 30°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.
