Strength and Heat Resistance plus Chemical Inertness
Ryton’s R-4’s strength, stiffness and chemical inertness in a wide range of environments makes it suitable for applications in the oil and gas, transportation and aerospace industries. There are no known solvents for Ryton PPS under 200°C. Additionally it offers a heat distortion temperature of 265°C, among the highest of the thermoplastics and room temperature stiffness greater than glass reinforced PEEK at a much lower cost.
Ryton R-4 PPS should be considered for parts in which dimensional stability under high loads and temperatures are important design factors. Examples are:
- Plasma torch insulators
- Downhole connector insulators
- Valve seats and high temperature seal
