PSU plastic hollow pepper balls are resistant to the corrosion of inorganic acid and alkali salts, but not to aromatic hydrocarbons and halogenated hydrocarbons. Polyarylsulfone (PSU plastic pepper ball) has high hardness, radiation resistance, good heat and cold resistance and self-extinguishing, and can be used for a long time at -100-175 degrees.

PSU plastic hollow pepper balls are widely used. In the field of electronics and electricity, PSU plastic pepper balls can be used to make various electrical parts such as contactors, connectors, transformer insulators, silicon controlled caps, insulating sleeves, coil frames, terminals and slip rings, printed circuit boards, bushings, covers, TV system parts, capacitor films, brush holders [1], alkaline battery boxes, etc. In the fields of automobile and aviation, PSU can be used to make protective cover elements, electric gears, battery covers, detonators, electronic ignition device elements, lamp parts, aircraft internal accessories and aircraft external parts, and spacecraft external protective covers. It can also be used for PSU to make illuminator baffles, electric drives, sensors, etc. The demand for polysulfone polymers used to make cabin parts in the world market continues to grow, mainly because such polymers release less heat, produce less smoke and diffuse less toxic gases when burning, which fully meets the use requirements of safety regulations; In the kitchen products market, PSU can replace glass and stainless steel products to make steam plates, coffee containers, microwave cookers, milk and agricultural products containers, egg cookers and milking machine parts, drinks and food distributors. PSU is a non-toxic product, which can be made into appliances that repeatedly come into contact with food. As a new transparent material, PSU is superior to any other thermoplastic in hot water resistance and hydrolysis stability, so it can be used to make coffee pots.
