PES showing high heat resistance and stable electrical properties.
Polyether sulfone (PES) with high heat resistance and stable electrical resistance Polyether sulfone is widely used as a high-performance plastic with excellent heat resistance and mechanical strength. By adding additives, we have successfully developed PES that also possesses stable surface resistance. 1. **Heat Resistance**: PES can maintain its shape and performance even in high-temperature environments, capable of withstanding temperatures above 200°C. 2. **Electrical Resistance**: Surface resistance is controlled between 10⁶ and 10¹², preventing the generation of static electricity and the adhesion of dust. 3. **Chemical Stability**: It shows high resistance to acids, alkalis, and oils, remaining stable against chemical agents. 4. **Mechanical Strength**: It has high tensile strength and impact strength, demonstrating excellent durability.
