PPSFull name: Polypara-phenylene sulfide; English name: polyphenylene sulfide; abbreviated name: PPS.Pure PPS resin has moderate mechanical strength, but its strength and rigidity are significantly increased after being reinforced with glass fiber or carbon fiber or filled with minerals, along with excellent creep resistance and fatigue resistance. It features high surface hardness, Rockwell hardness > 100HR, tensile strength > 170MPa, flexural strength > 220MPa, notch impact strength > 16MPa, and flexural modulus > 3.5×10^4.PPS has excellent chemical resistance, second only to PTFE, and is insoluble in any organic solvent below 200°C. It resists inorganic acids, bases, and salts, except for strongly oxidizing acids. Additionally, it is highly stable against various radiations. PPSPrimarily used in the electronics and electrical field, including transformer frames, high-frequency coil frames, plugs, sockets, wiring brackets, contactor drum sheets, and various parts.
