Abstract
A composition which can provide foamed moldings and foamed electric wires having a small average cell size and a high foam content and causing fewer sparks. The composition includes a fluororesin (A) and a compound (B) which is a sulfonic acid or a salt thereof. The sulfonic acid is represented by the following formula (1): F(CF2)nSO3H (1) wherein n is 4 or 5, or the following formula (2): F(CF2)nCH2CH2SO3H (2) wherein n is 4 or 5. Also disclosed is a foamed molding formed from the composition and a method for producing a foamed molding.
