High Temperature Resistant Wear Resistant Flame Retardant PSU sheet
PSU resin board rods have numerous excellent characteristics. It is a high-performance thermoplastic engineering plastic with excellent mechanical strength, high temperature resistance, and chemical corrosion resistance. PSU resin board rods can maintain stable performance over a wide temperature range and can be used for a long time in high-temperature environments. It has high hardness, strong impact resistance, and good insulation performance. Widely used in the fields of electronics and electrical engineering, mechanical manufacturing, chemical engineering, etc., it can be used to make insulation parts, mechanical components, corrosion-resistant containers, etc. It is a reliable and versatile engineering material.
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.
