What is PPSU material

2025-06-07 14:46:13 PPSU
PPSU (polyphenylsulfone) is a high-performance engineering plastic belonging to the sulfone polymer family (including PSU and PES). It boasts excellent comprehensive properties and finds wide applications in high-end industrial and consumer product fields.

Chemical Structure and Characteristics

  1. Chemical Name: Polyphenylsulfone resin

  2. Molecular Structure: Features a main chain with sulfonyl groups (-SO?-) and phenylene groups (-C?H?-), endowing it with strong molecular chain rigidity and outstanding thermal stability.

  3. Core Properties:

    • High Temperature Resistance: Long-term service temperature of ~180–200°C, with short-term tolerance to higher temperatures, superior to most engineering plastics (e.g., PC, PA).

    • Chemical Corrosion Resistance: Excellent tolerance to acids, alkalis, oils, solvents, and other chemicals, with low susceptibility to stress cracking.

    • High Strength and Rigidity: Stable mechanical properties, excellent impact and creep resistance, maintaining structural strength even at high temperatures.

    • Transparency: Some grades are transparent or translucent with high light transmittance (similar to PC).

    • Hygienic Safety: Compliant with FDA and EU food contact standards, suitable for medical and food applications.

    • Hydrolysis Resistance: Resistant to water absorption and degradation in high-temperature, high-humidity environments, suitable for steam sterilization (e.g., medical device disinfection).

Primary Application Fields

  1. Medical Field:

    • Surgical instruments (e.g., handles, forceps), medical containers, dialyzer components, and dental equipment, leveraging its high-temperature resistance (autoclave-compatible) and corrosion resistance.

    • Baby bottles and nipples (替代傳統 PC 材質,避免雙酚 A 風險).

  2. Aerospace and Automotive Industry:

    • Aircraft interior components (e.g., seat brackets, ventilation ducts) and automotive engine components (e.g., water pump casings, sensor housings), capable of withstanding high temperatures and fuel corrosion.

  3. Electronics and Appliances:

    • Heat-resistant electrical accessories such as coffee machine components, microwave tableware, and hair dryer casings; electronic components like integrated circuit board supports and connectors.

  4. Industrial and Consumer Products:

    • Food processing equipment (e.g., oven components, food molds), dishwasher accessories, and high-end sports equipment (e.g., diving mask frames).
