High rubber backing multi-layer ABS system which exhibits improved chemical resistance to HCFC blowing agents

摘要

Multilayer sheets of an acrylonitrile-butadiene-styrene resin layer and a relatively high rubber acrylonitrile-butadiene-styrene resin layer are provided which are thermoformable. The multilayer sheets exhibit resistance to halogenated blowing agents which escape from foamed-in-place insulation. The multilayer sheets can be thermoformed to provide equipment liners such as refrigerator liners, dishwasher liners, car interior panels, and appliance housings.
