PPSU
PPSU stronger and better in chemical resistance than PEI. It can operate in temperatures up to 180°C.
Our PPSU is based on PPSU from Solvay. PPSU is an excellent choice for under-hood automotive applications and medical devices requiring repeated steam sterilization. The hydrolysis resistance is excellent compared to other amorphous thermoplastics. In addition, it also resists common acids and bases over a broad range of temperatures.
- Heat resistance up to 220°C
- Excellent chemical and thermal resistance
- Good hydrolysis resistance
- Flame retardant
- High strength and toughness
