PURPOSE:To obtain the title composition which has excellent yield resistance and sealing properties, and an excellent sound insulating effect, and is suitable for insertion between a vehicle tank and a body panel, by incorporating ZnO and/or PbO and a plasticizer into a polymer blend of a butadiene/acrylonitrile copolymer and PVC. CONSTITUTION:100pts.wt. polymer blend consisting of 60-80wt.% butadiene/ acrylonitrile copolymer and 20-40wt.% PVC is mixed with 150-400pts.wt. ZnO and/or PbO; 5-30pts.wt. plasticizer such as dibutyl adipate; and if necessary, a vulcanizing agent, a vulcanization accelerator, and age resistor, a filler, a coloring agent, a flame retardant, etc. |
