ABSTRACT:
Compositions for a tip seal for a scroll type compressor are proposed which are low in friction coefficient, high fluidity in a molten state and highly durable in a compressor using a substitute Freon. The composition comprises 2-10 wt % of fluororesin, 5-20 wt % of carbon fiber, and 75-93 wt % of polyphenylene sulfide resin containing 90 mol % or more of a repeating unit represented by the formula: ##STR1## The composition has a melt viscosity of 1200-3000 poise. Also, a method of manufacturing a plurality of such tip seals simultaneously is proposed.
