Food Contact Grade GPPS Granules High Gloss and Rigidity for Transparent Injection Molding

Product Description

Product Description

GPPS (General Purpose Polystyrene) is a thermoplastic resin produced via free radical polymerisation of styrene monomers, with the molecular formula (C8H8)n. It is the most fundamental and widely used category in the polystyrene family.As the most fundamental and widely used core category in the polystyrene family, GPPS is favored by various industries due to its simple synthesis process, mature production technology, balanced comprehensive properties and high cost-performance ratio. It serves as a key raw material in the field of general plastics, bridging the gap between low-cost basic materials and high-performance engineered plastics, and plays an irreplaceable role in promoting the development of packaging, electronics, daily necessities and other downstream industries.

Core Characteristics:

1.High Transparency: Boasts a light transmittance of over 90%, comparable to glass. Widely recognised as "transparent plastic", it is ideal for directly manufacturing a wide range of transparent end products.
2.Superior Rigidity: Features excellent hardness and bending resistance, with exceptional dimensional stability post-moulding and minimal deformation.
3.Easy Processing: Offers outstanding melt flow performance, compatible with diverse processes including injection moulding, extrusion, and thermoforming. It works efficiently within a broad processing temperature range (160–220°C), ensuring high moulding productivity.

Applications

It is widely used in transparent packaging containers (food boxes, cosmetic bottles), electronic and electrical components (lampshades, transparent casings), daily necessities (stationery, toys), simple optical components (light guide plate substrates) and other fields.
