PPSU material, whose full name is polyphenylene sulfone resin, is an amorphous thermoplastic. It features high transparency, high hydrolysis stability, and can withstand repeated steam sterilization. PPSU is commonly used to make products such as baby bottles and medical devices.

PPSU material has the following characteristics: 1. High transparency: PPSU material is highly transparent, offering a clear appearance and excellent light transmission. 2. High hydrolysis stability: PPSU material maintains good hydrolysis stability even under high temperature and high pressure conditions, and is not easily affected by hot water or steam. 3. Chemical corrosion resistance: PPSU material is resistant to chemical corrosion and has good resistance to acids, alkalis, alcohols, ketones, and other chemicals. 4. High temperature resistance: PPSU material has a melting point as high as 280°C, allowing it to remain stable in high-temperature environments, making it suitable for applications requiring high-temperature processing. 5. Low moisture absorption: PPSU material has low moisture absorption, enabling it to maintain good performance in humid environments. 6. Good processability: PPSU material has excellent processability and can be processed using various methods such as injection molding, extrusion, and blow molding. The application range of PPSU material is very broad. Here are some common applications: 1. Baby bottles: The safety and stability of PPSU material make it highly suitable for manufacturing baby bottles, and it has become one of the mainstream materials for baby bottles on the market. 2. Medical devices: PPSU material's excellent corrosion resistance and antibacterial properties make it widely used in medical devices, such as syringes, infusion sets, and surgical instruments. 3. Food packaging: The transparency and high-temperature resistance of PPSU material make it an ideal choice for food packaging, such as juice bottles, coffee bottles, and other food containers. 4. Electronics and electrical appliances: PPSU material's low moisture absorption and high insulation properties make it widely used in the electronics and electrical fields, such as electronic components, circuit boards, and plugs. 5. Automotive parts: PPSU material's high-temperature resistance and chemical corrosion resistance make it suitable for automotive parts, such as fuel lines and air filters. It is important to note that different application fields have varying performance requirements for PPSU material. Therefore, when selecting PPSU material, it is necessary to consider the specific application environment and requirements.
