The weathering resistance of
fluorosilicone (fluorosilicone rubber) is very good. The following is a detailed analysis of the weathering resistance of fluorosilicone:
1. Overview of weathering resistance
Fluorosilicone is a high-performance elastomeric material with excellent weathering resistance. This means that under normal test conditions, fluorosilicone is not prone to obvious aging. Even under particularly harsh conditions, such as long-term exposure to the outdoors, fluorosilicone can maintain good performance.
2. Weathering resistance performance
Performance retention after long-term exposure: After long-term outdoor exposure tests, fluorosilicone can still maintain good elasticity. Even under long-term ultraviolet rays and harsh climatic conditions, its physical and mechanical properties have only slight changes.
Tensile strength and elongation at break: The tensile strength and elongation at break of fluorosilicone specimens placed in different locations are reduced to 75% of the original performance for more than 10 years. This shows that fluorosilicone can maintain high mechanical properties during long-term weathering.
3. Weathering resistance application examples
In practical applications, fluorosilicone is widely used to manufacture various parts that need to be exposed to outdoor environments for a long time due to its excellent weathering resistance. For example, in the aerospace field, fluorosilicone is used to manufacture seals such as O-rings for fuel pipelines on aircraft. These seals need to maintain stable performance in various harsh environments, and fluorosilicone is widely used because of its excellent weathering resistance.
4. Weathering resistance mechanism
The weathering resistance of fluorosilicone is mainly due to its special chemical structure and composition. Fluorine silicone contains fluorine atoms in its molecular chain, which makes its molecular chain have higher stability and anti-aging performance. At the same time, fluorosilicone also has excellent ozone resistance, and no cracks or cracks were found after dynamic or static tests.
In summary, fluorosilicone has very excellent weathering resistance and can maintain stable performance in outdoor environments for a long time. This feature makes fluorosilicone have broad application prospects and important strategic significance in aerospace, military industry, automotive industry and other fields.
