Material of viton fkm rubber
Viton FKM rubber is a high-performance fluorocarbon elastomer known for its exceptional resistance to chemicals, heat, and ozone. It’s a copolymer of hexafluoropropylene (HFP) and vinylidene fluoride (VDF), with varying ratios depending on the specific grade.
Viton’s resistance to a broad range of chemicals, including fuels, oils, acids, and bases, makes it ideal for demanding applications like seals, gaskets, and hoses in automotive, aerospace, and industrial settings. It can withstand high temperatures up to 300°C (572°F), offering excellent performance in harsh environments.
Viton FKM rubber also exhibits exceptional resistance to weathering, ozone, and UV radiation, ensuring long-term durability. Its low permeability to gases and its resistance to compression set make it suitable for demanding applications like aerospace seals and hydraulic systems.
However, Viton has limitations. It can be brittle at low temperatures, and its processing can be challenging due to its high viscosity.
