Polyphenylene sulfide (PPS) polymer is a semi-crystalline, high-heat resistance thermoplastic engineering plastic. Types of PPS compounds include both the cross linked and linear type.

Polyphenylene sulfide (PPS) is a polymer formed by the substitution pattern of the sulfur atom and the phenyl ring in the para position. The molecular structure of its molecular structure contains a high degree of stability of chemical bonds, so that the thermal degradation and chemical reactions have a high molecular stability. At the same time, the molecular structure of the polymer is also easy to form a crystal lattice with thermal stability, therefore, PPS is a crystal melting point up to 285°C(545°F) about the semi crystalline polymer. Due to the characteristics of its molecular structure, PPS is usually formed in the combustion of carbon residue, so that the material has the inherent flame retardant properties. PPS has not been found in less than 200°C(392°F) or so, soluble in any solvent.
