Product Description
GPPS Resin/GPPS granules/GPPS Compound/GPPS Powder/GPPS Particles/GPPS Virgin Recycled/ GPPS Bead
GPPS description:
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.
