What is PPS? Polyphenylene sulfide (PPS), first mass-produced in 1972, is a semi-crystalline polymer made up of alternating sulfur atoms and phenylene rings in a para-substitution 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. Because of its molecular structure, PPS 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 °C. PPS is often used as a lower cost alternative to replace PEEK at low to moderate temperatures.
Characteristics: - An excellent combination of both long-term and short-term thermal stability - High temperature resistance with continuous use temperature of 230 °C - Exceptionally high modulus and creep resistance - Outstanding resistance to a wide variety of aggressive chemical environments - Precision moulding to tight tolerances with high reproducibility - Inherent non-flammability without flame retardant additives - Dielectric and insulating properties stable over a wide range of conditions
