Storage conditions: airtight at room temperature, protected from light, ventilated and dry place
Stability:
1. Stable under normal temperature and pressure, avoid light, open flame, high temperature,
2. Polyethersulfone resin has excellent heat resistance, physical and mechanical properties and insulation properties. The heat distortion temperature is 200～220℃, and the continuous use temperature is 180～200℃. It is resistant to steam at 150-160℃, and is not corroded by acids and alkalis at high temperatures. The modulus remains almost unchanged between -100°C and 200°C, especially when used above 100°C, the denaturation is the most excellent one of the thermoplastic resins, especially the glass fiber reinforced PES resin is better than some thermosetting resins. . The coefficient of linear expansion is small. It has the same impact resistance as polycarbonate, and unreinforced resin can be riveted. It is self-extinguishing and has excellent flame resistance without adding any flame retardant. PES is resistant to gasoline, engine oil, lubricating oil and other oils and cleaning agents such as freon. Its solvent cracking resistance is the best among amorphous resins, but its resistance to polar solvents such as acetone and chloroform is not good.
