| PPS-hGR20 is glass reinforced PPS compound, which is filled with glass fiber based on the PPS resin. The characteristic of PPS compounds includes good mechanical properties, high creep resistance, high temperature resistance, friction resistance, flame resistance, chemical resistance, excellent electrical insulation properties, arc resistance, low mold shrinkage, easy processing good dimensional stability, and radiation resistance. Owing to its high performance, PPS-hGR20 is widely used in electronic appliances, such as: connectors, sockets, frequency dividers, components and shells of various apparatuses and instruments. PPS can be used to make elements where high strength, high temperature resistance, electrical insulation are all-important in aviation. It is also used for precise appliance plugs, high hardness outer shells, and high temperature resistant parts in military.&& |
