What is PSU Plastic

In the global application of engineering plastics, PSU plastic has gradually expanded from the traditional fields of electronics and medical care to household appliances, automobiles, energy and drinking water systems. Its unique advantage lies in the fact that it can withstand high temperatures while maintaining long-term stable physical properties. Enviroplas PSU ENV48-NC570 belongs to high heat resistance grade and hydrolysis resistance grade materials, and enhances the characteristics of detergent resistance, oxidation resistance, chemical resistance, hydrocarbon resistance and oil resistance, providing purchasers with a choice that combines reliability and design flexibility.

01 | Analysis of material properties and characteristics

High heat resistance grade: Heat distortion temperature is approximately 171℃ (340℉), maintaining dimensional and performance stability in high-temperature environments, suitable for long-term use.

Hydrolysis resistance grade: It can maintain stable performance even in hot water or steam environments, and is particularly suitable for hot water components of medical devices and household appliances.

Detergent resistance and oxidation resistance: Cope with frequent cleaning and disinfection, reducing the risk of aging and cracking.

Chemical resistance: Resistant to erosion by acids, alkalis and various types of chemicals, it is applied in laboratory and industrial scenarios.

Hydrocarbon resistance and oil resistance: Suitable for automotive fuel parts, lubricating oil systems and energy equipment.

Design freedom: Black, transparent and clear colors are available, taking into account both functional and aesthetic requirements.

High process compatibility: Injection molding is suitable for the production of precision components, with a low shrinkage rate, reducing the risk of mold modification and scrapping.
