Description :

　　20% fiberglass reinforced PSU S2010G4, BASF Germany, high rigidity and high strength

　　The PSU grade with medium viscosity injection molding has high rigidity and strength.

　　Application: Printer parts, printing machine parts, good mechanical strength, V-1 V-0

　　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 toughness 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 ℃), and radiation resistance.

　　Overall, PSU is an amorphous polymer with high mechanical properties and heat resistance, and its main performance characteristics are as follows:

　　① The mechanical properties of PSU are superior to those of general engineering plastics such as POM, PA, and PC. Even at 150 ℃, the tensile strength can still reach 60MPa. At this time, 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.

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