Viton/FKM Rubber
We only use virgin FKM Fluoroelastomer polymer in the production of all of our Fluoroelastomer (FKM) products, which we purchase from the top producers worldwide. The aerospace industry required a high-performance elastomer, hence fluoroelastomers were initially launched more than 50 years ago.
Fluoroelastomer rubber, commonly known as FKM rubber, is a versatile and high-performance material widely used in various industries. It exhibits exceptional resistance to heat, chemicals, and harsh environments, making it ideal for demanding applications. FKM rubber is composed of fluorine, carbon, and hydrogen atoms, which give it remarkable stability and resistance to degradation. Its unique properties make it highly sought after in industries such as automotive, aerospace, oil and gas, and chemical processing.
One of the key advantages of fluoroelastomer rubber is its excellent resistance to high temperatures. It can withstand continuous exposure to temperatures ranging from -40°C to 200°C (-40°F to 392°F), and even higher for short durations. This heat resistance makes FKM rubber suitable for applications where other elastomers would fail, such as engine seals, gaskets, O-rings, and other components in automotive engines and industrial machinery operating in extreme conditions.
Another notable characteristic of fluoroelastomer rubber is its exceptional chemical resistance. It can withstand exposure to a wide range of chemicals, including oils, fuels, acids, bases, and solvents. This chemical stability allows FKM rubber to maintain its mechanical properties and sealing performance even in aggressive environments. As a result, it is extensively used in chemical processing plants, oil refineries, and fuel handling systems, where resistance to corrosive substances is crucial.
Fluoroelastomer rubber, or FKM rubber, is a highly durable and versatile material with exceptional heat and chemical resistance. Its ability to withstand extreme temperatures and harsh environments makes it a preferred choice in demanding applications across various industries. From automotive to aerospace, FKM rubber plays a critical role in sealing, gasketing, and other components where reliability and longevity are paramount
