DESCRIPTION
ChaoYue brand high-temperature silicone O Ring is specially designed to challenge extreme temperature environments. Made of gas-phase silicone rubber precision manufacturing, our O-ring provides the market's leading high-temperature resistance while maintaining excellent elasticity - long-term resistance of -60°C to +250°C, and short-term peak of up to 350°C. When ordinary rubber seals fail, our products still maintain complete sealing performance.

PRODUCT CHARACTERISTICS AND ADVANTAGES
1. Excellent high temperature resistance
- Main characteristics: It can work stably for a long time in the range of -60°C to +250°C, with short-term peak tolerance of +300°C to +350°C, and will not melt or drip.
- Advantages: At high temperatures when most rubber materials fail, it can still maintain sealing integrity and prevent thermal degradation.
2. Excellent thermal stability and low compression permanent deformation
- Main characteristics: It can still maintain excellent elasticity and resilience at high temperature, and the compression permanent deformation rate is low.
- Advantages: Ensure that the sealing ring will not be permanently deformed or lose the sealing force under continuous high temperature and pressure, and extend the service life.
3. Excellent weather resistance and aging resistance
- Main characteristics: It has strong resistance to ultraviolet rays, ozone, radiation and extreme climate change.
- Advantages: It is suitable for outdoor, aerospace and occasions with oxidizing environments, and has a long service life.
4. Good chemical inertness
- Main characteristics: water resistance, steam resistance, weak acid resistance and weak alkali resistance, and good resistance to some oils and chemicals.
- Advantages: Suitable for steam sterilization, hot water cleaning and some chemical media environments.
5. Safe and environmentally friendly, meet multiple certifications
- Main characteristics: tasteless and non-toxic, in line with the requirements of FDA (food grade), LFGB, RoHS, REACH and other regulations.
- Advantages: It can be used in food processing equipment, medical equipment, drinking water systems and other fields with high requirements for hygiene and safety.
6. Excellent electrical insulation performance
- Main characteristics: high resistivity, good dielectric strength.
- Advantages: It is very suitable for the insulation sealing of high-temperature electrical appliances, lighting equipment (such as LED lampshade sealing), and electric heating components.
