The fire retardance,thermotolerance and mechanical properties of the attapulgite filled rigid PVC plastics were stUdied. The results showed that the fire retardance increased with theIncreasing of attapulgite filled. When attapulgite≤10 pasts, the tensile strength, impact strength and thermotolerance increased with the increasing of attapulgite filled. Though the experiments, it is feasible in technology to use attapulgite treated with coupling agents as filler of rigid PVC profiles.
