GPPS
General Purpose Polystyrene
Crystal-clear general purpose polystyrene for rigid transparent applications.
01 Overview
GPPS is the transparent, rigid and dimensionally stable member of the styrenics family, used where optical clarity and low cost outweigh impact resistance. It is frequently blended with HIPS to tune the stiffness and toughness of sheet and thermoformed products.
