Advantages;
1. High heat resistance: the heat distortion temperature of PPA is up to 300°C or more, and the continuous use temperature can reach 170°C, which can maintain stable performance in high temperature environments.
2. Superior mechanical properties: in a wide range of temperatures and high humidity environment, PPA maintains its superior mechanical properties, such as strength, hardness, fatigue resistance and creep resistance.
3. Toughened grade: PPA combines superior toughness with a range of hardness and flexibility, making it a good choice for rigid fasteners requiring single use and for flexing in repetitive use.
4. Glass transition temperature: The glass transition temperature of PPA is around 255°C. Non-crystalline PPA is mainly used where barrier properties are required, while semi-crystalline PPA resins are mainly used for injection molding and other melt processing.
Applications:
1. Automotive industry: High-temperature resistant electronic connectors, sensor housings, fuel system components (such as fuel manifolds), turbocharger piping, etc. The heat resistance (long-term service temperature above 180°C) and chemical stability of PPA can replace metals, achieving lightweighting.
2. Electronics and electrical: 5G base station antenna covers, relays, switch components, chip packaging, etc. With excellent dielectric properties, low moisture absorption, and dimensional stability, it ensures the reliability of high-frequency signal transmission.
3. Industrial equipment: Pump and valve gears, bearing bushings, compressor blades, and other wear-resistant parts. The high mechanical strength and fatigue resistance of PPA can extend equipment life and reduce maintenance costs.
4. Consumer electronics: Smartphone clasps, drone structural components, smart home device housings. Through modification, it balances rigidity and toughness, simultaneously meeting the requirements of thin and light design and durability.
5. Medical and food equipment: Surgical instrument handles, disinfection trays, food contact-grade pump bodies. PPA materials certified by FDA/EU have both high-temperature steam sterilization resistance and food safety.
