Techtron®PPS Unfilled Virgin machining part

What is PPS material? PPS can also be called Polyphenylene Sulfide, is a kind of thermoplastic resin with phenyl sulfur group in the main chain of molecule.PPS combines the performance and cost-effectiveness in a way that is unmatched by other thermoplastic engineering plastics, with high mechanical strength, high temperature resistance, chemical resistance, flame retardant, good thermal stability and excellent electrical properties, which is widely used in automobiles, especially new energy vehicles, Electronic and electrical appliances, petrochemical and other fields.

Pure PPS due to the performance of brittle and rarely used alone, the application of PPS is mostly for its modified performance varieties, common glass fiber reinforced PPS, glass mineral filled PPS, carbon fiber reinforced PPS, etc., after modification of the Nabant PPS has more excellent performance, expanding its scope of application.

1. Heat resistance of PPS plastic: heat distortion temperature of 260 ° C or more, is currently one of the higher temperature thermoplastic engineering plastics. Long-term use temperature up to 220 ° C, short-term use temperature up to 260 ° C, and in the long-term working load and thermal load can still maintain high mechanical properties and dimensional stability, can be used for high temperature stress environment.

2. PPS plastic chemical resistance: PPS is known for its excellent chemical resistance, even at high temperatures. 200 ° C insoluble in any solvent. It has good resistance to different kinds of chemical media, and it is resistant to all automotive media, so Napan PPS has good applications in automotive parts, such as water pump housing, water pump rotor, water pump impeller, water pump motor housing, oil pump end cap, oil pump PCBA cover, insulating bobbins, four-way valve sliders, electronic expansion valve parts, piping and so on.

3. PPS plastic electrical properties: in the high temperature, high humidity, high frequency environment, has a high volume resistivity, surface resistivity, breakdown voltage, low dielectric constant and dielectric loss angle tangent, is an excellent insulating material, after modification of the disposal, can also be made into a good conductive properties of high strength materials. Because of the good electrical properties of Naban PPS plastic, so that it has a wide range of applications in the automotive three electric system components, such as connectors, IGBT modules, capacitor housings, sensors, coil skeleton, three-phase terminal, lithium-ion battery cover plate on the plastic, high-voltage terminals, seals, battery boxes and other automotive parts, PPS materials can be very good to drive.

4. PPS Plastic Dimensional Stability: PPS has very low water absorption, making it ideal for producing complex parts with very tight tolerances. The polymer exhibits excellent dimensional stability even when used in high temperature and high humidity conditions.

5. PPS plastic mechanical properties: PPS plastic has high hardness and strength, and has excellent creep and fatigue resistance, able to withstand greater pressure and wear. This makes PPS the preferred material in applications requiring high strength and wear resistance, such as automotive parts and mechanical parts.
