High Quality Good Flowability Colorable Pellet Plastics PSU Amber Polysulfone Resin

Polysulfone (PSU) is a tough, rigid, high-strength thermoplastics suitable for continuous use up to 300°F (149°C). It is resistant to oxidation and hydrolysis and withstand prolonged exposure to high temperatures and repeated sterilization. Udel® P-1700 polysulfone is highly resistant to mineral acids, alkali and salt solutions. Resistance to detergents and hydrocarbon oils is good, but the resin may be attacked by polar solvents such as ketones, chlorinated hydrocarbons and aromatic hydrocarbons.

Performance characteristics

①Mechanical properties. The tensile strength and bending strength of PSU are superior to those of general engineering plastics such as POM, PA, and PC. Even at 150°C, the tensile strength can still reach 60 MPa, while most general engineering plastics have lost their use value at this time. This property of still maintaining the mechanical properties it has at room temperature at high temperatures is beyond the reach of general engineering plastics.
② Thermal properties. The Tg of PSU is 190°C, and the heat distortion temperature is 175°C. It can be used for a long time at -100 to 150°C. Moreover, PSU has good heat and oxygen aging resistance. After 2 years of heat and oxygen aging at 150°C, the tensile yield strength and heat distortion temperature do not decrease but increase instead, and the impact strength can still maintain 55% of the original value.
③ Electrical properties. PSU has good electrical insulation, especially after being placed in a high-temperature environment and in water and moist air, it can still maintain good electrical insulation.
④ Chemical properties. PSU is relatively stable to common inorganic acids, bases, salts, aliphatic hydrocarbons, alcohols and oils, but it will be affected by strong solvents such as concentrated sulfuric acid and nitric acid. Some polar solvents such as ketones, halogenated hydrocarbons, aromatic hydrocarbons, and methyl formyl will cause it to dissolve and swell.
