Polyphenylsulfone (PPSU), commonly known as PPSU Material, is a high-performance engineering thermoplastic valued for its excellent heat resistance, mechanical strength, and outstanding chemical stability. As an advanced PPSU Polymer, this material delivers reliable performance in demanding applications where ordinary plastics fail. From medical grade PPSU components to industrial and food-contact parts, PPSU Plastic provides long-lasting durability even in harsh environments.
Compared to other high-temperature plastics such as PSU or PES, PPSU Resin offers enhanced toughness and superior resistance to repeated sterilization cycles—making it a trusted material choice in medical, aerospace, industrial, and consumer applications.
Key Properties of PPSU Material
1. High Heat Resistance
As a high heat resistance polymer, PPSU can withstand continuous service temperatures up to 180°C (356°F) and short-term exposure up to 260°C (500°F). This makes PPSU High Temperature Plastic ideal for environments where thermal stability is critical, such as medical sterilization chambers and automotive engine systems.
2. Superior Chemical Resistance
PPSU Chemical Resistance is one of its strongest advantages. It is unaffected by:
Acids and alkalis
Fuels and hydraulic fluids
Cleaning agents and disinfectants
This allows PPSU to maintain performance even under aggressive chemical exposure.
3. Exceptional Mechanical Strength
PPSU provides:
High impact strength
Dimensional stability
Resistance to stress cracking
This makes it suitable for engineering thermoplastic PPSU applications requiring structural reliability.
4. Low Moisture Absorption
PPSU maintains performance and size stability even in humid environments, enabling long-term functional reliability.
PPSU vs. PSU vs. PES: What’s the Difference?
| Property | PPSU | PSU | PES |
|---|---|---|---|
| Heat Resistance | ★★★★★ | ★★★★☆ | ★★★★☆ |
| Impact Strength | ★★★★★ | ★★★☆☆ | ★★★★☆ |
| Chemical Resistance | ★★★★★ | ★★★★☆ | ★★★★☆ |
| Cost | Higher | Medium | Medium |
Compared to PSU and PES, PPSU offers significantly better impact strength and hydrolysis resistance, making it the preferred choice for medical and high-stress applications.
