PPS ( polyphenylene Sulfide ) is a crystalline resin with very high thermal resistance. Its low co-efficient of linear thermal expansion and low water absorption results in high dimensional stability. It can be used at 2200C but due to its low glass temperature of 900C, care must be taken if used under high load, high temperature.
