摘要:
A blowing agent for thermoplastic foams such as extruded polystyrene foam is disclosed. The blowing agent is a blend of a low solubility blowing agent, such as 1,1,1,2-tetrafluoroethane, and a dichloroethylene such as trans-1,2-dichloroethylene. The blowing agent combination enhances processibility of thermoplastic foam.
