PPSU / PSU / PES
Polysulphones

This is a family of engineering thermally stable plastics with good electrical properties and excellent chemical resistance. These products also have a good thermal resistance, and outstanding dimensional stability.
Features:
- PSU: hard, high strength, transparent, sable in range -100°С ...150°С, applicable for medical using;
- PES: good stability to gamma-ray, flame retardant, high stiffness, good for medical issues, amber color;
- PPSU: transparent amorphous material, could be exploited at 185 - 190°С, stable to fuel and oil as well as to solvents.
Applications:
- engine room car parts;
- helmets (aerospace);
- electrical parts;
- parts of chemical and oil processing equipments.
