Date Apr. 20, 1995Disclosed is a foam structure of desirable mechanical strength made with a low molecular weight alkenyl aromatic polymer material and an inorganic blowing agent. The polymer material has an alkenyl aromatic polymer of a weight average molecular weight of 100,000 to 165,000. The foam structure can be made in processes with reduced pressure drop.
