PPS rod

Polyphenylene sulfide (PPS) is a highly rigid, high molecular crystalline polymer with excellent properties, wide applications, and outstanding performance

1. Excellent heat resistance, with a thermal deformation temperature exceeding 260 ℃ and a long-term use temperature of 220-240 ℃. Degradation in air at 700 ℃ At 1000 ℃, the inert gas still maintains 40% of its weight, and its short-term heat resistance and long-term continuous use thermal stability are superior to all current engineering plastics.

2. It has flame retardancy and can reach UL94V-0 level. When making flame-retardant products, no flame retardants need to be added, maintaining the high mechanical properties of the material itself.

3. Good mechanical performance, extremely strong rigidity, high surface hardness, and excellent creep resistance and fatigue resistance.

4. Excellent chemical resistance. At present, no solvent has been found that can dissolve PPS below 200 ℃. It also has strong resistance to inorganic acids, bases, and salts.

5. Good dimensional stability, low molding shrinkage, low water absorption, and low linear thermal expansion coefficient. It still exhibits good dimensional stability under high temperature or high humidity conditions. Therefore, it has a wide range of applications in various fields such as machinery, chemical engineering, instrumentation, and aerospace.

6. Excellent electrical performance, even under high temperature, high humidity, and high frequency conditions.

7. Outstanding wear resistance, which can be greatly improved by filling lubricants such as fluororesin and carbon fiber.

8. Resistant to radiation and capable of measuring 1 × 10 ^ 8 Gy, it is unparalleled by other engineering plastics and is an excellent material in electronic instruments, military, aerospace and other fields.

9. The melt viscosity of PPS resin is very low, with good fluidity and easy wetting contact with glass fibers. At the same time, it is easy to wet with various fillers. Glass fibers or inorganic fillers reinforced injection grade pellets prepared with PPS resin have extremely high tensile strength, impact resistance, bending resistance, and ductility.

10. PPS has a very high bonding strength to glass, aluminum, stainless steel, etc. Its bonding strength to glass is even greater than its cohesive strength. Due to its good corrosion resistance and bonding performance, it is easy to make lining for Huagong equipment.

11. Due to PPS's excellent corrosion resistance and difficulty in bonding, ultrasonic welding is its preferred bonding method.

The main application scope of PPS rod:

PPS electronic and electrical: micro electronic component packaging, connectors, connectors, sockets, coil frames, fine tuned capacitors, fuse bases.

PPS rod mechanical instruments: pump casing, pump wheel, tile, gear, pulley, universal head, sealing gasket, flange, counter, level gauge, flow meter components.

PPS automotive field: temperature sensors, vaporizers, evolutions, vaporization pumps, seat bases, water tank chambers. PPS stick household appliances: electric fan, microwave holder, dryer, coffee pot, rice cooker, hot air duct, hair perm machine, air conditioning compressor.

PPS military field: producing fighter jets, missile vertical tail fins, missile combustion chambers, aviation, aerospace, aircraft connectors, coil frames, instrument panels, and many other components, especially the main components of stealth fighters and bombers. The parts of nuclear submarines that are resistant to nuclear radiation include firearms, helmets, tents, containers, astronaut supplies, corrosion-resistant and wear-resistant components for warships and submarines, new tanks developed by the United States (in the production stage) and plastic tanks developed by the United Kingdom (in the experimental stage), etc.

PPS fiber and film: By blending PPS fiber with other synthetic fibers, high-performance industrial filter cloth and radiation resistant aerospace fabric can be produced. PPS film is an insulation material that can reach Class F and can be used to make capacitors, impedance electronic components, flat coil frames, wire coverings, masks, vaporizer separators, thermal printing materials, flexible disks, and photosensitive tapes for electronic photography.
