Grades of Toray PPS Resin, TORELINA™

The basic grades include the glass fiber reinforced type, which offers high strength and relatively excellent toughness, the glass fiber + filler reinforced type, which offers excellent dimensional accuracy, and the unreinforced type, which is low in strength but sticky. Each grade is available as the cross-linked polymer type, which has excellent creep properties and so on, and the linear polymer type, which offers excellent toughness. There are also other variations such as the high flow type, for which the amounts of reinforcement and polymer molecular weights are adjusted. Also in the lineup are elastomer improvement types, for which the low toughness, a weakness of PPS, is improved. In addition, special purpose grades are also offered, which have high sliding properties, high laser weldability, low levels of chlorine, tracking resistance, and other additional properties. For details, refer to the catalog.
