HIPS Resin (High Impact Polystyrene)

HIPS High Impact Polystyrene Brand:CHIMEI Model: PH-888G Grade:Injection Molding 25kg/kraft bag

HIPS Resin (High Impact Polystyrene) Description: Milky white opaque particle, density is1.05g/cm^3. melting temperature is 150~180 °C. The thermal decomposition temperature is 300 °C.

Soluble in aromatic hydrocarbons, chlorinated hydrocarbons, ketones (except I ketones and esters. ) and the ability of many mineral oil, organic acid, alkali, salt, lower alcohol and water solution, not boiling water.

The physical and chemical properties: The HIPS high impact polystyrene is a impact-resistant polystyrene products which by adding in polystyrene poly butyl rubber particles.

The HIPS is composed of PS and butadiene modified and, because of the impact strength of PS is low, the product is very crisp, good toughness and butadiene butadiene, joined after the PS impact properties of 2~3 times improve. Purpose : The TV set, printer, audio products shell, small household appliances.

Injection molding process: polystyrene is good fluidity, good processing performance, easy coloring, good size stability. Injection molding, extrusion, blow molding, available foam, thermal forming, bonding, coating, welding, machining, printing and other processing methods into various parts.

This is especially suitable for injection molding, injection molding material can be dried directly use. But in order to improve the quality of the products, but at 55 °C ~70 °Cblast oven drying 1~2h.

The specific processing conditions is roughly: barrel temperature 200°C60~80°C, die temperature, injection temperature 170°C to 220 °C, injection pressure ratio is 1.6~4.0. After the molding products should be in the infrared lamp or blast drying oven, in 70 °C2~4h.

A high strength, easy processing, excellent thermal deformation performance, with UL94HB rating, with the United States Food and Drug Administration requirements, suitable for injection molding.
