RYTON 40% GLASS-FIBER REINFORCED POLYPHENYLENE SULFIDE (PPS)
PHILLIPS RYTON 40% GLASS-FIBER REINFORCED POLYPHENYLENE SULFIDE R-4-02XT BLACK
Chevron/Phillips Chemical Company - Phillips Ryton R-4-02-XT Black
Polyphenylene Sulfide is a semi crystalline thermoplastic polymer that can withstand heat and chemical environments too aggressive for other thermoplastics. Used in the predominate glass filled form, Polyphenylene Sulfide has mechanical, thermal, and electrical properties that rival those of thermosets without sacrificing the processability of thermoplastics. Those properties make Polyphenylene Sulfide especially useful to designers who face challenging electrical or automotive applications. We offer this material in black only.
