GPPS has excellent transparency and stiffness but very low impact resistance.
HIPS is a resin that provides enhanced impact strength through rubber-grafting. Rubber toughening makes possible a wide range of properties, depending on rubber content, morphology, size, degree of grafting, molecular weight of matrix PS, and other conditions.
KUMHO GPPS has good transparency, mold ability, and heat stability; therefore, processing by injection molding or extrusion molding is very economical.
Kumho HIPS has excellent impact strength, mold ability and heat-resistance. Its wide range of grades with various melt flows and impact strengths allows the selection of the appropriate grade for a specific application.
