Polyphenylene Sulfide (PPS)

Polyphenylene sulfide (PPS) is a crystalline thermoplastic resin with exceptional thermal, chemical, electrical and flame retardant properties. The unique properties of PPS is given by its highly stable chemical bonds in its molecular structure, moreover PPS has very thermally stable crystalline lattice imparts it to have a high melting point of about **5°C.
 
Key Features
Thermal Resistant properties
Excellent short-term and long-term thermal resistance properties;

Dimensional Stability properties
Very low molding contraction rate and coefficient of linear thermal expansion with low moisture absorption means outstanding dimensional stability even at high temperature and high humidity;

Chemical Resistance properties
Excellent chemical resistance, very close to that of fluropolymers (PPS has no known solvent below **0℃);

Mechanical properties
PPS offer high strength and high rigidity with minimum decline in mechanical properties even at high temperatures. Outstanding fatigue and creep resistance;

Flame Retardant properties
PPS is inherently flame retardant and readily conform to UL*4 V0 requirements;

Electrical properties
Very low dielectric and dissipation factor even at high temperature, humidity and high frequencies environment;

Molding properties
Could meet tight injection molding tolerances with high reproducibility.
