Abstract

An easily applied low-density natural rubber latex foam contains an expanding agent which pref. comprises a saturated aliphatic hydrocarbon, an aliphatic hydrocarbon contg. fluorine or a mixt. of these; it is thixotropic and its density is 0.02-0.3 (0.06) g/cm3. Prefd. expanding agent is isobutane or a mixt of CCl2F2 and C2Cl2F4.
