POLYSTYRENE CRYSTAL FORMULA/ CHEMICAL COMPOSITION MATERIAL DESCRIPTION All polystyrenes have excellent process ability and a low heat capacity value leading to process energy reduction. With its high stiffness and low density, all articles made from polystyrene have excellent strength-to-weight ratio offering many environmental benefits, such a reduction of weight, nonrenewable resource savings, transportation costs and carbon footprint. EXTRACTION PROCESS Methanol extraction out of polystyrene at 100 ‘C and requires 6 hours BASIC PROPERTIES
