Wear resistant transparent PSU S2010 German BASF Easy Flow Food Container Medical Equipment

Description :

　　PSU S2010 BASF Food Container from Germany; Wear resistant medical equipment; Transparent; High temperature resistance; Compliance extrusion level for food contact

　　The molecular structure of PSU is a polymer composed of linear macromolecules formed by connecting phenethyl groups with isopropylidene, ether, and sulfone groups. The substituent structure of isopropylidene is symmetrical and non-polar, which can reduce intermolecular forces. In addition, the presence of ether bonds endows the polymer with certain initial and melt processing properties; Sulfone and phenyl groups make the main chain of the polymer exhibit greater rigidity, making it difficult for PSU to crystallize; The oxygen atom on the sulfone group of the diphenyl group is symmetrical, and the sulfur atom on the main chain is in an oxidized state, giving the polymer excellent antioxidant capacity. The sulfone group forms a highly conjugated benzene sulfone structure with adjacent benzene rings, giving the polymer rigidity, high thermal stability (Td>426 ° C), and radiation resistance. Overall, PSU is an amorphous polymer with high mechanical properties and heat resistance The mechanical properties of PSU, including tensile strength and bending strength, are superior to general engineering plastics such as POM, PA, and PC. Even at 150 ° C, the tensile strength can still reach 60MPa. At this point, most general engineering plastics have lost their practical value, and the property of maintaining their mechanical properties at room temperature at high temperatures is unmatched by general engineering plastics.

　　Thermal performance: The Tg of PSU is 190 ° C, with a thermal deformation temperature of 175 ° C. It can be used for a long time at -100~150 ° C, and PSU has excellent heat and oxygen aging resistance. After 2 years of thermal oxygen aging at 150 ° C, the tensile yield strength and thermal deformation temperature do not decrease but increase, and the impact strength can still maintain the original value of 55%.

　　Electrical performance: PSU has good electrical insulation, especially after being placed in high temperature environments, water, and humid air, it can still maintain good electrical insulation.

　　Chemical properties: PSU is relatively stable against general inorganic acids, bases, salts, as well as fatty hydrocarbons, alcohols, and oils. However, it is susceptible to strong solvents such as concentrated sulfuric acid and nitric acid, as well as certain polar solvents such as ketones
