PPSU is an amorphous thermoplastic with high transparency and high hydrolytic stability. Articles can be subjected to repeated steam sterilizations.

PPSU, scientific name: Polyphenylene sulfone resin (Polyphenylene sulfone resins) PPSU polyphenylene sulfone resin is a product of Polysulfone (PSF) for short. It is a novel thermoplastic engineering plastic, which refers to a polymer compound containing a sulfone group and an aromatic nucleus in the molecular main chain, which is non-crystalline.

Widely used:

1. Suitable for making heat-resistant parts, insulating parts, wear-resistant and wear-resistant parts, parts of instruments and meters, and medical device parts. Polysulfone is suitable for making low-temperature working parts.

2. Polysulfone is often used in the electronic and electrical industry to manufacture integrated circuit boards, coil tube frames, contactors, sleeves, capacitor films, and high-performance alkaline battery casings.

3. Polysulfone is used in household appliances for microwave oven equipment, coffee heaters, humidifiers, hair dryers, cloth steamers, beverage and food dispensers, tableware, drinking glasses, baby bottles, etc. It can also be used in precision structural parts of clocks, copiers, cameras, etc. instead of non-ferrous metals.

4. Polysulfone has passed the relevant specifications in the US pharmaceutical and food fields and can replace stainless steel products. Because polysulfone is resistant to steam, hydrolysis, non-toxic, high temperature steam disinfection, high transparency, good dimensional stability, etc., it can be used as a surgical tool tray, sprayer, fluid controller, heart valve, pacemaker, gas mask, Dental tray, etc.

** Because PPSU is a safe material, it does not contain endocrine-causing carcinogenic chemicals (environmental hormones: bisphenol A), and as a material with excellent heat resistance, the heat resistance temperature is as high as 207 degrees. Due to repeated high temperature boiling, steam disinfection. It has excellent drug resistance and resistance to acid and alkali. It can withstand the washing with ordinary potions and detergents without chemical changes. Lightweight and drop resistant, it is the best in terms of safety, temperature resistance, hydrolysis resistance and impact resistance. But the price is relatively expensive.
