Product Description

Product Description
General Purpose Polystyrene (GPPS) 


Virgin/recycled GPPS resin 



It's for Injection molding. 

Description: 

GPPS is a colorless, odorless, tasteless and shiny, transparent particles. Light, cheap, low water absorption, good color, dimensional stability, good electrical properties, products, transparent, easy processing. 

GPPS is low water absorption, in a wet environment can still maintain its mechanical properties and dimensional stability. Excellent electrical properties, volume resistivity and surface resistivity are high, and independent of temperature, humidity changes, are not subject to corona discharges. Radiation resistance is also very good. 

GPPS is solubled in aromatic hydrocarbons, chlorinated hydrocarbons, aliphatic ketones and esters, but only swell in acetone. Resistant to the action of certain mineral oils, acids, alkalis, salts, lower alcohols and their aqueous solutions. Low water absorption, in wet conditions can still maintain its mechanical properties and dimensional stability. Excellent electrical properties, volume resistivity and surface resistivity are high, and not affected by temperature and humidity changes, and is not affected by corona discharge. Radiation resistance is also very good. 

Application: 

Polystyrene fluidity, good processing performance, easy to color, good dimensional stability. Available injection molding, extrusion, blow molding, foam molding, thermoforming, bonding, coating, welding, machining, printing or the like into various parts. Especially suitable for injection molding, the material generally may not be used directly without drying when injection molding. 
Used fot pharmaceutical packaging, Cosmetic packaging, Lighting fixture, Insulation, Electric packaging, etc.
