High performance fibers polyphenylene sulfide fiber

High-performance polymers, such as polyphenylene sulfide (PPS) (Ry-ton), have excellent resistance to elevated temperatures, and this property can be enhanced by the incorporation of reinforcing fibers such as graphite fibers. 

The major applications of LCP films in electronics are multilayer boards and multichip modules, and flexible printed circuits. Current materials used in the.se applications include polyimide film, high performance thermoplastic film such as polyphenylene sulfide and polyetherether ketone, and fiber reinforced composites such as quartz fiber-polyimide. The price of these materials for electronic packaging is in the range of. 50 to. l(K)/lb, so LCPs can compete very effectively at their current prices. Based on a two to three times increase in price...
