It’s a high-performance elastomer that’s often used in applications where traditional rubber materials cannot withstand extreme conditions.Fluoroelastomer (FKM, commonly known as Viton®) is one of the most expensive rubber materials. Other costly rubbers include perfluoroelastomer (FFKM), fluorosilicone, and some specialty silicones. Their price comes from advanced chemical resistance, high heat tolerance, and complex production.FKM is a family of fluorocarbon-based fluoroelastomer materials defined by ASTM International standard D1418 and ISO standard 1629. It is commonly called fluorine rubber or fluoro-rubber. FKM is an abbreviation of Fluorkautschukmaterial (i.BRP offers FKM brown and black rubber sheet, also known as fluoroelastomer rubber. It’s commonly known by its brand name, a registered trademark of DuPont. FKM brown and black rubber is well known for its excellent (400°F/200°C) heat resistance and offers excellent resistance to aggressive fuels and chemicals.
What does FKM stand for?
FKM stands for fluoroelastomer and is a type of synthetic rubber known for its excellent resistance to chemicals, oils and heat. It’s a high-performance elastomer that’s often used in applications where traditional rubber materials cannot withstand extreme conditions. Despite its toughness, FKM rubber is soft and skin-friendly. It gently contours to your wrist without stiffening or requiring a break-in period, making it ideal for comfortable, all-day wear.Unlike TPU, FKM rubber is heat resistant, chemical resistant, and extremely durable, making it the perfect choice for long term wear. It resists UV damage, repels dust, and maintains its flexibility over time, ensuring a luxurious feel on the wrist.While silicone is your best bet for PFHxA-free watch bands, here are some other common materials that are generally safe and widely available. Canvas: This lightweight material is breathable and comfortable while still being sturdy enough to handle adventures and workouts.If you’re after a watch strap that can handle rough conditions, frequent outdoor use, or just want something that feels a bit more premium, FKM Rubber is the way to go.

What are the disadvantages of FKM?
FKM: FKM is known to swell in fluorinated solvents and cannot be used with molten or gaseous alkali metals. FKM is a premium product, due to its chemical makeup. So it does come with a higher price tag than other non-fluorinated hydrocarbons and low temperature grades can be especially costly. FKM is predominantly used in the aerospace or automotive industries thanks in part to the wide temperature operating range, from -15°F(-26°C) to 500°F(260°C), making it a suitable material for interior engine components and exterior landing gear or instrumentation panels.Fluorocarbon, also known as FKM (fluoroelastomer), is a synthetic rubber material known for its exceptional chemical resistance and temperature tolerance. It is derived from fluorinated hydrocarbons and is highly resistant to oils, fuels, acids, and a wide range of chemicals.FKM applications FKM (FPM, Viton®, Fluorel®) resist mineral oils and greases, aliphatic, aromatic and also special chlorinated hydrocarbons, petrol, diesel fuels, silicone oils and greases. It is suitable for high vacuum applications.About FKM Fluorocarbon The working temperature range is considered to be -26°C to +205°/230°C (-15°F to +400°/440°F).
Why is FKM so expensive?
Why is FKM So Expensive? FKM is more expensive than many other elastomers due to its complex manufacturing process and the high cost of raw materials. The fluorine-based compounds used in FKM are expensive, and the vulcanization process is more specialized compared to standard rubbers. FKM is a copolymer made of highly fluorinated hydrocarbons and developed during the 1950s. FKM seals display very good resistance to media, ozone and aging. The material is also stable in fuels as well as petroleum-based oils and greases, along with aliphatic and aromatic hydrocarbons.Viton (FKM)®, known for its high heat resistance, can last over a decade in applications involving high temperatures. Silicone seals, popular for their flexibility and temperature resistance, can last over 10 years in the right conditions.Chemicals: Viton™ can withstand a range of chemicals, including oils, acids, silicone fluids and gasses as well as halogenated and aromatic hydrocarbons.
