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).
