General Purpose Polystyrene (Gpps)

General Purpose Polystyrene (GPPS)

Product origin: Petrochemical Plant

Grade: Injection Grade

Origin: Petrochemical Plant

GPPS, general-purpose polystyrene or crystal-clear polystyrene, is fully transparent yet brittle, a CD case, and is widely used in food packaging applications or jewel cases.

As its name suggest the item is used for general purpose. The range of its use is large starting from Advertising Light Box to Insulators and even in Interior Decoration.

About the Product : It is a synthetic aromatic polymer made from the monomer styrene. General-purpose polystyrene is clear, hard, and rather brittle. It is an inexpensive resin per unit weight. It is a rather poor barrier to oxygen and water vapor and has a relatively low melting point. Polystyrene is one of the most widely used plastics, the scale of its production being several billion kilograms per year.

Properties:



Polystyrene (PS) plastic is a naturally transparent thermoplastic that is available as both a typical solid plastic as well in the
form of a rigid foam material. PS plastic is commonly used in a variety of consumer product applications and is also particularly
useful for commercial packaging.
Polystyrene (PS) for Prototype Development on CNC Machines and 3D Printers: Polystyrene is available in sheet stock, rod stock,
and in various shapes. It is a great candidate for subtractive machining processes on a CNC machine. Colors are usually limited to
clear, white, and black although colors can be added and it is an excellent candidate for external painting.
Polystyrene (PS) for� Injection Molding:
General Purpose Polystyrene (GPPS) and High Impact Polystyrene (HIPS) are probably the most commonly used PS resins for injection
molding. GPPS is clear, but brittle (think of a CD jewel case) while HIPS is opaque and much less brittle.
