A fluoroelastomer made of synthetic rubber, viton is used in some engine gaskets. When a vehicle is involved in a fire, horrific injuries have been reported to unsuspecting individuals who have come into contact with the breakdown products of fluoroelastomers.
These stories have been reported all over the world. These come back every few years, causing new panic, so hopefully this will clear up the record.
Under pressure close to the worker’s fingers, a clear liquid was ejected as the device was dismantled. This caused discomfort, and over the course of a few days, a deep burn that had not been treated developed, eventually necessitating the amputation of a portion of his finger.
HSE looked into the incident and found that hydrofluoric acid (HF) was made (from hydrogen fluoride gas in water) by repeating the experiment.
Free hydrogen ions can cause corrosive burns, and fluoride ions can penetrate tissue and cause chemical burns. However, calcium gluconate gel can be used to treat it quickly.
Viton (FKM fluorocarbon), the pioneering fluoroelastomer, has contributed to setting a new performance standard for today’s advanced fuel and engine systems since its introduction.
Because it is a necessary component for meeting today’s and tomorrow’s more stringent requirements, it is now even more effective against extreme heat, chemicals, fuel mixtures, and fuel additives.
For fuel seals, head and intake manifold gaskets, quick-connect o-rings, fuel injection seals of all kinds, caulks, and advanced fuel hose components, Viton is the preferred polymer.
Designers frequently choose Viton to replace less thermally and chemically stable materials in an era when longer warranties, hotter engines, more aggressive lubricants, and stricter environmental regulations are pushing traditional elastomers to their limits.
There is a Viton product and grade for every need, from compounds to caulks. It’s not surprising that Viton fluorocarbon is still the fluoroelastomer that is most frequently requested and specified for demanding automotive sealing applications.
The EV Fluoroelastomer motor seal accounted for $XX Billion in 2022 and is anticipated to reach $XX Billion by 2030, registering a CAGR of XX% from 2023 to 2030.
J-Flex – J-Flex is an official licensee of the Chemours Viton product and they also offer other grades, and have one of the widest ranges of elastomers available worldwide.
There are specific requirements and to find the correct elastomer for the intended purpose.
A new fluoroelastomer family was introduced by Asahi Glass , FEPM based on an alternative copolymer of TFE and propylene. It is marketed under the trade name AFLAS
