PPS
PPS is an organic polymer composed of aromatic rings linked together by sulfur. Synthetic fibers and textiles made from this polymer are known to be resistant to chemicals and temperatures up to 240°C. PPS, which is hard and opaque, is used to make filter fabric for coal boilers, papermaking felts, electrical insulation, special membranes and gaskets.
PPS (Polyphenylene Sulphide) is usually available unfilled, up to 65% mineral filler and glass fiber reinforced (30-40%).
Features:
- Continuous service temperature up to 240°C
- Short-term temperature resistance up to 270°C
- Flame retardant due to intrinsic property
- Very high chemical resistance (insoluble in all known solvents below 2000°C)
- Very high water absorption
- Very high creep resistance even at high temperatures
Creep tests show the behavior of a material under long-term stress in different conditions (especially elevated temperatures) and help to select the best material for parts subjected to long-term stress. PPS (Polyphenylene Sulfide) shows very high creep resistance at high temperatures and therefore PPS is the material of choice for many very high demand applications.
Polyphenylene Sulfide is one of the materials with the highest heat resistance among thermoplastics. Some reinforced PPS grades reach HDT (Thermal Bending Temperature) of 2700°C.
PPS (Polyphenylene Sulfide) is intrinsically flame retardant. This can be seen from the fact that PPS achieves UL 94 V-0 and some classes, even at 5VA, without any flame retardant additive.
