GPPS are glossy, transparent particles. Light quality, low price, low water absorption, good coloring, dimensional stability,
good electrical properties, transparent products, easy processing.GPPS are soluble in aromatic hydrocarbons, chlorinated
hydrocarbons, aliphatic ketones and esters but can only swell in acetone. It is resistant to some mineral oils, organic acids,
bases, salts, lower alcohols and their aqueous solutions. It has low water absorption and can maintain its mechanical properties
and dimensional stability in humid environment. Excellent electrical performance, volume resistance and surface resistance are
high, and is not affected by temperature, humidity changes, also not affected by corona discharge. Radiation resistance is also
very good.
