polyphenylene sulfide(pps)is a polymer made up of alternating sulfur atoms and phenylene rings in a para subsitution pattern.

the highly stable chemical bonds of its molecular structure impart a remarkable degree of molecular stability

toward both thermal degradation and chemical reactivity,the molecular structure also readily packs into a very

thermally stable crystalline lattice, hence pps is a semi-crystalline polymer with a high crystalline

melting point of about 285 ℃(545F).because of its molecular structure,pps also tends to char during combustion,

making the material inherently flame retardant.pps has not been found to dissolve in any

solvent at temperatures below about 200 ℃（392F).

in addition to low water absorption,pps also has good dimensional stability and excellent electrical properties,

furthermore,pps is chemically very stable even at high temperatures.
