About VITON:
VITON fluororubbers are capable of operating at high temperatures, when they offer physical and mechanical properties superior to most other elastomers. The increase of temperature has relatively little effect on the oil resistance and chemical resistance of fluorine rubber. Even after continuous aging in 204C or intermittent aging in 260C oven, fluororubbers will maintain a certain elasticity. The operating conditions at high temperatures are usually 232°Cx3000h, 260°Cx100h, 288°Cx240h, and 316°Cx48h.
In all the industrial elastomers, fluorine rubber resistance to liquid and chemical media performance is better than any non-fluorine elastomer, it has excellent oil resistance, aviation fuel resistance, lubricant resistance, resistance to most mineral oils. Fluorine rubber has very low permeability for most substances, and also has excellent performance in low antioxidant automotive fuel penetration. Aliphatic and aromatic hydrocarbons are common solvents for elastomers, but VITON rubber has good durability against them.
Products Application
Viton is widely used in the aerospace field for the following accessories and components
Aircraft seals
Fluorine rubber has excellent oil resistance, fuel resistance and high temperature resistance, so it is often used in aircraft seals, such as door seals, window seals, aerospace engine seals, etc. They effectively prevent the leakage of oil, fuel and air while withstanding high temperature and pressure environments.
Aero engine parts
Fluorine rubber is used in aerospace engines to manufacture various seals, such as sealing rings of turbine components, inlet seals, combustion chamber seals, etc. These seals need to be resistant to high temperatures, corrosion and oxidation to withstand extreme working environments.
Fuel System
In aerospace, fluoroelastomers play an important role in fuel systems. It is used to make fuel lines, connections and seals to ensure the reliability and safety of fuel systems. Viton has high compatibility with various fuel types and can withstand high pressure and high temperature requirements.
Spacecraft seals
Viton is also widely used in seals on spacecraft. For example, it is used to manufacture cabin seals, propulsion system seals, airtight hatch seals, etc. Viton's high temperature, vacuum and radiation resistance make it an ideal choice for spacecraft sealing.
It should be noted that the requirements in the aerospace field are very strict and have high requirements on the performance and reliability of materials.
