PURPOSE: Title composition that is made by adding a hydrated A-type zeolite, thus having improved heat resistance, harmlessness, high dimensional stability and transparency. n CONSTITUTION: A halogen-containing resin (100pts.wt.) is mixed with 0.2W 10, preferably 1W5 parts, of a dehydrated A-type zeolite that has the formula (1.0± 0.2)M 2 O.Al 2 O 3 .(1.9±0.5)SiO 2 (0.5W6.0) (M is Na, K, NH 4 , Ca, Mg, Sr), contains crystal water and has less than 10 micron particle size and they are kneaded. The heat stability of plasticizer-containing halogen-containing resin is improved. n COPYRIGHT: (C)1980,JPO&Japio |
