What kind of material is PPSU

PPSU is an amorphous thermoplastic with high transparency and high hydrolytic stability. The article can be subjected to repeated steam sterilization. Also known as polyphenylene sulfone, it is a novel thermoplastic engineering plastic, which refers to a polymer compound containing a sulfone group and an aromatic nucleus in the main chain of the molecule, and is non-crystalline. The appearance is a slightly amber transparent material, and the color is the lightest polysulfone material. At the same time, it has high strength and high toughness, and its comprehensive performance is the best in polysulfone. Main properties: heat distortion temperature up to 220°C, long-term use temperature up to 180°C, melting point at 310°C; density is 1.29g/cm³; fire-retardant grade reaches V-0; can withstand 1000 high pressure steam sterilization cycles at 134°C; Excellent toughness, impact strength up to 690J/m; excellent long-term thermal hydrolysis stability.
