PURPOSE:To obtain the titled molding material having excellent strength and capable of effectively exhibiting the characteristic features of a filler, by aggregating and attaching filler powder to microscopic node of a porous texture of a polytetrafluoroethylene and including a silicone rubber in the tissue. CONSTITUTION:A polytetrafluoroethylene is mixed with a powdery filler (e.g. alumina, carbon black, barium titanate, etc.) and the mixture is rolled or drawn at a rate of 1-100m/min to effect the fibrillation of polytetrafluoroethylene. A liquid silicone rubber is attached to and impregnated in the fibrillated texture and baked to obtain the objective material.
