Also known as Styrofoam, polystyrene is one the most frequently used service thermoplastics. This resin is a petroleum-based plastic created from the styrene monomer. A light-weight material, polystyrene is about 95% air and has excellent insulation qualities. High molecular weight thermoplastic resins are often formed by the free-radical polymerization of styrene monomer. This can be initiated by heating alone, but more heating in the presence of free-radical initiator (such as benzoyl peroxide) is more effective. Common processing procedures are adapted mass polymerization or solution polymerization, suspension polymerization, and expandable beads for foam.
