HIPS is the development of rubber-modified polystyrene (ie high-impact polystyrene, HIPS) since 1950, mainly to solve the impact brittleness of PS . By adding rubber to the polystyrene substrate, various grades of high-impact polystyrene with different properties can be produced. In recent years, various special grades of HIPS have been developed. There are flame retardant grades, stress crack resistance grades, high gloss grades, extremely high impact strength grades, glass fiber reinforced grades and low residual volatilization grades. They are used in many applications It has been able to compete with expensive engineering resins in the field. The outstanding characteristics of impact-resistant polystyrene are easy processing, excellent dimensional stability, high impact strength and high rigidity. HIPS is only in heat resistance. There are certain limits in oxygen permeability, ultraviolet light stability and oil resistance. The performance of HIPS has a great relationship with the content of rubber phase in the system.
