GPPS Applications:
The material can be used as packaging filler, pressed into board, molded into products, or delivered on sheets or rolls. Its characteristic dimensional stability permits it to be employed in low strength construction, and in its natural translucent form makes it suitable for food processing applications.
GPPS Granular Application:
1.Food packaging.
2.Electrical industrial, instrumentation, communications equipment industry and other various instruments has been widely used as a shell, lamp, optical parts, equipment parts, transparent windows mirror, transparent model, acid, chemical storage tank, acid tank transport, telecommunications components, high frequency capacitors, high frequency insulation pads, brackets, inserts and frozen insulating materials.
3.All kinds of daily necessities,such as Plastic Cutlery, Toys.
