What is the main performance of PPS Sheet

Excellent heat resistance: its melting point exceeds 280°C, heat distortion temperature exceeds 260°C, and long-term use temperature is 220-240°C. Degradation in air at 700°C At 1000°C, the inert gas still maintains 40% weight. The short-term heat resistance and long-term continuous use thermal stability are superior to all current engineering plastics. Specially modified varieties, heat distortion temperature up to 350 °C.

Its own flame retardant: Polyphenylene ether flame retardancy can reach UL94-0 level, the oxygen index (LOI)> 57%. The chemical structure of polyphenylene ether itself makes it have a good fire-retardant properties, without the need to add flame retardants.

Good mechanical properties: strong rigidity, high surface hardness, Rockwell hardness> 100 HR, tensile strength> 170 MPa, bending strength> 220 MPa, notched impact strength> 16 MPa, flexural modulus> 3.5 × 104, and excellent Creep resistance and fatigue resistance.

Excellent chemical resistance: No solvents that can dissolve polyphenylene ether below 200°C have been found so far. They are highly resistant to inorganic acids, bases, and salts.

Good dimensional stability: mold shrinkage is very low, less than 0.0025%, absorption rate is less than 0.05%, linear thermal expansion coefficient is also small. It shows good dimensional stability under high temperature and high humidity conditions. Therefore, it has a wide range of applications in machinery, chemicals, instruments, instruments, aviation, aerospace, and ships.

Excellent electrical properties: Polyphenylene ether has excellent electrical properties under high temperature, high humidity and high frequency conditions, and its volume resistivity is 1×1016Ω. Cm, the surface resistivity is 1×1015Ω, and the electric strength is >18KV/mm.

Outstanding wear resistance: Through the filling of lubricants such as fluorine resin and carbon fiber, its wear resistance can be greatly improved, and the friction coefficient is 0.01-0.02.

Radiation resistance: The radiation resistance reaches Gy 1×108, which is a new material that other engineering plastics cannot match. It is the only ideal for radiation resistance in the fields of electronics, electrics, machinery, instruments, aviation, aerospace, military, etc. The fine material.

Good processing performance: PPS resin has low melt viscosity, good fluidity, and easy wet contact with glass fiber, so it is easy to fill the filler, and the injection-grade pellets reinforced by the glass fiber or inorganic filler prepared by the PPS resin have extremely high anti-flexibility. Sex, impact resistance, bending resistance and ductility. Above its melting point can be unified forming.

Good adhesion to metals and non-metals: PPS has a very high bond strength especially to glass, aluminum, titanium, stainless steel, etc. Adhesion is up to level 1. Good adhesion to glass, extremely suitable for lining of chemical equipment.
