Fluorosilicone, also known as fluorosilicone rubber, is a versatile class of materials that combines the advantageous properties of silicone rubber with the excellent chemical resistance and thermal stability of fluoroelastomers. It exhibits excellent chemical resistance to fuels, oils, solvents, and other harsh chemicals, making it ideal for applications in the automotive, aerospace, and industrial sectors. Fluorosilicone also has a wide operating temperature range, typically from -60°C to 200°C, enabling it to withstand extreme temperature variations.
Fluorosilicone is a synthetic elastomer composed of a backbone of silicon and oxygen atoms, with fluorine atoms attached to the silicon atoms. This unique molecular structure endows fluorosilicone rubber with excellent properties, making it suitable for demanding applications in harsh environments. Leveraging our expertise in the field, Alfa Chemistry offer a comprehensive range of fluorosilicone products, such as fluorosilicone elastomer, and fluorosilicone oil, etc.
Fluorosilicone (FVMQ), fluorocarbon elastomer (FKM), and silicone (VMQ) are three types of elastomers commonly used in various industries. Each of these materials has its unique characteristics and properties, making them suitable for different applications. By understanding these key features, you can make informed decisions when choosing an appropriate elastomer for their specific requirements.
