Overview :

PPSU (polyphenylene sulfone) is an amorphous polymer with superior rigidity and toughness, offering better impact resistance and chemical resistance than polyetherimide (PEI). PPSU is one kinds of amber transparent material, easy to color and processing, and its HDT can reach 196 ℃. Withstands over 1000 cycles of steam sterilization@134℃without any significant loss of properties.According to the different application environment, the molding method can be injection, extrusion, blow and casting.As the highest performance material of sulfone polymers, PPSU has been approved by IS010993, NSF, ACS, WARS, UL94, Reach and RoSH. So PPSU has been widely used in medical sterilization boxes, handles of dental instruments, aircraft interiors and food trays, PEX water pipe joints, ventilator humidification tanks, baby bottles and other fields.
