PPSU Plastic Material

PPSU (Polyphenylsulfone) is a high-performance thermoplastic polymer known for its exceptional properties and wide range of applications. It offers excellent heat resistance, mechanical strength, and chemical stability, making it suitable for demanding industrial, medical, and everyday environments.

Key Features of PPSU

1.High Heat Resistance
PPSU has a glass transition temperature (Tg) of up to 220°C and a long-term use temperature of approximately 180°C. It can withstand short-term exposure to even higher temperatures, ensuring superior performance in high-temperature environments.

2.Outstanding Chemical Resistance
PPSU resists acids, bases, and a wide range of solvents, including aliphatic and aromatic hydrocarbons. It remains stable under chemical exposure, even at elevated temperatures.

3.Superior Mechanical Properties
PPSU exhibits excellent impact strength and toughness, making it resistant to cracking or breaking. Its fatigue resistance outperforms many other engineering plastics, ideal for applications with repeated stress.

4.High Transparency and Customizability
Naturally amber-colored and translucent, PPSU can be colored with masterbatches, allowing for custom designs in medical devices and consumer products.

5.Exceptional Sterilization Resistance
PPSU is highly resistant to repeated high-temperature steam sterilization, withstanding over 1,000 cycles without degradation. This makes it ideal for medical and food-grade applications requiring frequent sterilization.

6.Biocompatibility
PPSU complies with ISO 10993 and USP Class VI standards, making it safe for use in medical devices or containers that come into contact with the human body or food.
