Ineos Americas LLC's styrenics division has developed two resins geared to appliance applications such as refrigerator liners.
The Channahon, Ill.-based division said Avantra 2720 and 535K high-impact polystyrenes can be used together to provide strength at low temperatures, chemical resistance and a high-gloss surface. Avantra 2720 is the base resin for large-sheet uses and 535K is suitable for a cap layer.
Ineos claims Avantra 2720 provides improved stiffness, allowing downgauging and cost savings. The 535K HIPS is tough, flexible and stain-resistant in extrusion and injection molding uses.
