Chemical-Resistant Polyphenylene sulfide (PPS)Hexagonal Nuts

PPS  (polyphenylene sulfide ) is a high-performance thermoplastic resin with the following properties:

1. Physical properties: PPS material is hard and brittle, with high crystallinity (55%~65%), and difficult to burn. Its heat resistance is high: continuous use temperature up to 240 ℃, heat distortion temperature up to 265 ℃, can be used for a long time in an environment of 200 ~ 220 ℃, low-temperature resistance up to -40 ℃. Chemical-Resistant Polyphenylene sulfide (PPS) Hexagonal Nuts mechanical strength, rigidity, and flame retardant are Chemical-Resistant Polyphenylene sulfide (PPS) Hexagonal Nuts have very high mechanical strength, rigidity, and flame retardancy, as well as good dimensional stability and wear resistance.

2. Chemical properties: PPS is stable to most acids, esters, ketones, phenols, aliphatic hydrocarbons, aromatic hydrocarbons, chlorinated hydrocarbons, and other chemicals and is only subject to strong oxidizing acids such as concentrated sulfuric acid, concentrated nitric acid, and aqua regia.

3. Electrical properties: Chemical-resistant polyphenylene sulfide (PPS) Hexagonal Nuts have good electrical insulation, even at high temperatures, high humidity, and high-frequency environments; their volume resistivity and insulation resistance will not change, and they are excellent insulating material fasteners.

4. Processing characteristics: PPS is fluid and easy to mold, with almost no shrinkage holes or concave spots. It has a good affinity with various inorganic fillers and reinforcing materials, including glass fiber, carbon fiber, polyacrylamide fiber, metal fiber, etc., of which glass fiber is the main one.

5. Modified properties: PPS/PTFE, PPS/PA, PPS/PPO, and other alloys have been commercialized. For example, PPS/PTFE improves the brittleness, lubricity, and corrosion resistance of PPS, while PPS/PA is a high-toughness alloy.

In summary, Chemical-Resistant Polyphenylene sulfide (PPS) Hexagonal Nuts are a comprehensive performance of special engineering plastics best fasteners for high temperature, high humidity chemical corrosion, and other harsh environments, commonly used in the manufacture of heat-resistant parts, insulating parts, and chemical instrumentation.
