3. Introduction
 Polystyrene is the fourth biggest polymer produced in the world after
polyethylene, polyvinyl chloride and polypropylene.
 High Impact Polystyrene (HIPS) is a versatile, economical and impact-resistant
plastic that is easy to machine and fabricate.
 HIPS is often specified for low strength structural applications when impact
resistance, machinability, and low cost are required.
