Phenyl Silicone Rubber (PSR) is a new type of organosilicon material with excellent high-temperature stability and chemical resistance. Its molecular structure contains phenyl groups (-C6H5), which gives it outstanding performance in both high and low-temperature environments, especially in heat resistance, aging resistance, and antioxidation.
The main characteristics of phenyl silicone rubber include:

1. High-Temperature Resistance: It can be used in a wide temperature range of -50°C to +250°C, with certain modified types capable of withstanding even higher temperatures.
2. Excellent Electrical Insulation: Maintains superior electrical performance even in harsh environments.
3. Chemical Resistance: Offers strong resistance to many chemicals, such as acids, alkalis, and oils.
4. UV and Ozone Aging Resistance: The phenyl structure helps it effectively resist UV and ozone degradation when used outdoors.
   Phenyl silicone rubber is widely used in industries such as automotive, electrical electronics, aerospace, seals, and gaskets, particularly in high-temperature environments for sealing and insulation applications.
