Gpps Grades

General-purpose polystyrene is the low-cost member of the plastics family. Properties of the amorphous polymer include hardness, rigidity, optical clarity, dimensional stability, and excellent processibility.

Because GPPS resins possess excellent transparency, mold ability, heat stability and low specific heat, they are very economical in injection or extrusion processes. In addition, because they are available in various grades, the range of choice is very wide, depending on use. Grades are classified depending on manufacturing method, in other words, changes in processing conditions or quantity of additives. There are general purpose, high flow, high heat resistance, high rigidity, extrusion molding and high transparent grades.

General Purpose Poly Styrene grades are available in ground chips form. Granulation is done exclusively on orders. The following are the grades available in this:

(1) GPPS Natural Chips
(2) GPPS Translucent Red Chips
(3) GPPS Translucent Green Chips
(4) GPPS Translucent Blue Chips
(5) GPPS Double Super Black Granules
