Menene Polyphenylene Sulfide (PPS)?

Polyphenylene Sulfide (PPS) wani nau'in nau'in thermoplastic ne na Semi-crystalline tare da kodadde launin rawaya. Yana da wurin narkewa na kusan 290°C da yawa kusan 1.35 g/cm³. Kashin bayansa na kwayoyin halitta-wanda ya hada da sauye-sauyen zoben benzene da atom na sulfur-yana ba shi tsayayyen tsari mai tsayin daka.

An san PPS don babban taurin sa, kyakkyawan kwanciyar hankali na zafi, juriya na sinadarai, da ƙarfin injina. Saboda kyakkyawan aikinsa, PPS an san shi sosai a matsayin ɗayan manyan robobi na injiniya guda shida, tare da polyethylene terephthalate (PET), nailan (PA), polycarbonate (PC), polyoxymethylene (POM), da polyphenylene ether (PPO).
