General Information

• Density: Density of all SC grades (GPPS) is 1.04 g/cc and SH grades (HIPS) is 1.03 g/cc.
• Mould Shrinkage: Shrinkage of Supreme polystyrene is in the range of 0.4 – 0.7%.
• Food contact: All Supreme grades comply with FDA 21CFR 177.1640 and other European regulations for food contact applications. It remains the responsibility of the user to verify that the finished product also conforms with these regulations.

• High heat distortion resistance grades with intermediate strength and flow.
• High strength grade SC202EL for medium thickness applications like CD jewel boxes, audio cassettes, office accessories, medical packaging and injection blow molded medical bottles.
• Medium flow, high toughness grade SC202LV for fast cycling products like CD jewel boxes and stationery.
• Good flow and strength grade SC203EL for injection molding of houseware, cutlery, stationery, novelties, cassettes, labware etc.
• Easy flow, high strength grade SC203LV for long flow path applications like thin wall cups, containers, vials, jars and cutlery produced in multicavity tools. Ideal for glossy cap layer on HIPS sheet.
• Grade SC206 which flows easily and has good strength for general injection molding applications like tableware, crystalware, beads, bangles, timepieces and cosmetics.
• A low molecular weight grade SC208 which flows extremely easily for high speed injection molding of thin wall parts that have relatively low strength requirements. Also suitable for hangers, compounding and concentrates.

• High impact grade SH825 with easy flow and heat distortion resistance for injection molding of houseware, cooler bodies, watch cases, wall clocks, novelties etc.
• High impact versatile grade SH731 with normal flow and good low temperature toughness for extrusion and injection molding. Applications include thermoformed food and non-food packaging, formed industrial items, hot/cold beverage glasses, audio/video cabinets, business machines, ball pens etc.
• High flow grade SH03 with excellent toughness for gas assist molding of TV cabinets and high speed molding of thin walled parts. Also suitable for AC grills, toys, computer accessories, refrigerator components etc.

• High heat, high melt strength grade SC201E for OPS packaging, XPS insulation board, foam trays, extruded clear sheets, lighting profiles, medical disposables, closures and caps.
• Medium heat, high toughness grade SC201LV for large refrigerator parts like crisper trays, ball pens, office accessories.
• Matte finish grade SH2157 with increased environmental stress cracking resistance against agents like Freon II, HCFC 141 b, Cyclopentane and fatty foods. Suitable for refrigerator liners and fatty food packaging.
• High gloss grade SH400M with balance of toughness and strength for injection molded styling parts of appliances like washing machines, air conditioners, refrigerators, toys, camera, pen barrels etc.
• High heat, high toughness grade SH2114 for extruded sheets and thermoformed deep draw industrial applications.
