General Purpose Polystyrene

GPPS COMPOUNDS

GPPS is an engineering thermoplastic compound resin reinforced with 10-50% of minerals and/or additives. It is a solid product that is generally see through and compressed in granule form to produce a range of products. It is has a high gloss finish and is clear. GPPS covers both Extrusion and Moulding grades, ESCR, High Gloss and super High Impact grades, Flame Retardant and Pre Coloured Resins. These compounds are ideal for clear product application and also suitable for large volume clear molded products.

TYPES

GPPS Mineral (Calcium/Talc) Compounds
GPPS Standard (Black/White/Colour) Compounds
GPPS Effect (Fluorescent, Sparkle, Transparent etc) Compounds
