What is the difference between silicone and fluorosilicone?

What is the difference between silicone and fluorosilicone?

Fluorosilicone is a variation of silicone rubber that maintains excellent high temperature stability and mechanical properties, while offering greater resistance to fuel, oil and other chemicals. These added benefits also come with a cost—fluorosilicone is typically five times the cost of silicone.

Is Viton A fluorosilicone?

Both materials are well suited for use in the -30 to 180°C range. Fluorosilicone has an advantage in lower temperatures and FKM has an advantage in higher temperatures.
…
FKM (Viton®)

What is Viton not compatible with?

Do not use Viton with acetone, esters, amines, organic acids, acetic acid, MEK, ethyl acetate, highly polar chemicals, etc. Viton is generally serviceable in dynamic applications to temperatures of -18 to -23 °C.

What is the difference between fluoroelastomer and silicone?

Fluorocarbon is able to withstand higher temperatures at 250° C, although Silicone with the addition of heat stabiles and fame retardants, can exceed this and provide temperature ratings of up to 300° C making it an idea for high temperature applications.

Is fluorosilicone fungus resistance?

50 durometer fluorosilicone is fungus resistant and takes a low compression set. Consider using 50 durometer fluorosilicone gasketing material in applications where the gasket requires silicone, but where extreme conditions exist.

Is fluorosilicone an elastomer?

Like silicone, fluorosilicone rubber is a long-lasting elastomer that is stable and compression set resistant across temperature extremes, but unlike silicone, fluorosilicone contains trifluoropropyl groups that enhance its chemical resistance to non-polar solvents, fuels, oils, acids, and alkaline chemicals.

Is FKM and Viton the same?

These rubber compounds give exceptional heat resistance with compatibility across many fluids or chemical exposures. The most commonly known name for these compounds is “Viton,”™ which has become the generic name for all FKM polymers and rubber compounds.

What are fluorosilicone O-rings used for?

Common Applications

Electrical housing seals. Aerospace fuel systems. Automotive fuel emission control systems. Fuel pumps and tank seals.

Are Viton and FKM the same?

Fluoro-Elastomer is usually referred to as FKM FPM or as VITON™ after the popular brand which produces it. You may see this rubber listed in different places with these different names, but they are all one and the same. Originally developed by Du Pont, it is produced by a number of companies around the world.

What is the difference between EPDM and Viton?

Viton® rubber is a fluoro elastomer, whereas epdm rubber is ethylene-propylene-diene-monomer. The primary differences between Viton® and EPDM is in their chemical resistance and temperature ranges. Both have different properties and applications for general industrial use.

Is fluorosilicone a fluoroelastomer?

Fluorosilicones account for almost 8% of the world market for fluoroelastomers. Perfluoroelastomers are a specialty high-performance elastomer with exceptional chemical resistance properties and high-temperature stability.

Is FKM same as PTFE?

FKM offers greater temperature resistance but falls short of PTFE’s properties in terms of chemical resistance. While PTFE is slightly less thermally resistant but offers much in the way of non-adhesive properties. It’s a dead heat!

Is fluorosilicone fungus inert?

Style AG50FS is naturally UV and ozone resistant and offers extreme resistance to fuels and solvents. 50 durometer fluorosilicone will perform in extreme low and high temperature, with a service temperature of -80 F to +500 F. 50 durometer fluorosilicone is fungus resistant and takes a low compression set.

What is fluorosilicone rubber used for?

Use of fluorosilicone rubber
Typical applications include static seals in fuel systems for cars and in aerospace engineering as well as diaphragm valves for crankcase ventilation. Fluorosilicone rubber is also used in hoses, e.g. turbocharger hoses, and in O-rings.

Is FPM same as Viton?

FKM / FPM / Viton®
The terms FKM, FPM and Viton® are all different designations that stand for the same base material, which is fluoro rubber.

What is the difference between EPDM and FPM?

FPM is often used in high-temperature applications due to its excellent heat resistance and oxidative stability, whereas EPDM is employed when low temperature leak tightness is required.

What is fluorosilicone rubber?

What is Aflas?

AFLAS® is unique fluoroelastomer that has superior amine resistance and electrical insulation compared to conventional fluoroelastomers. AFLAS® is highly suitable for critical applications where exceptional reliability is required.

What type of material is FPM?

Fluorocarbon is an elastomers based on fluororubber (FPM, FKM), also known as VITON (registered trade name of Du Pont), which can be used for U-cups, lip seals, packings, wipers and special seals. Its outstanding properties include high resistance to heat, ozone, many chemicals and it is all-weather-proof.

Is FPM the same as Viton?

What is fluorosilicone sealant?

Master Bond one and two component fluorosilicone adhesives, sealants, gasketing, potting compounds protect against erosion/corrosion and withstand exposure to oils, fuels, solvents and other aggressive fluids.

Is EPDM rubber fungus resistance?

Generally, EPDM(ethylene propylene) and Neoprene(chloroprene) are the polymers that we see utilized for fungus resistance in the gasketing industry.

Is silicone rubber fungus resistance?

Stockwell Elastomerics offers silicone rubber for gasket applications requiring fungus resistance. Most silicone formulations do not have any fungus inhibitor added since silicone is inherently fungus resistant.

Is Aflas the same as PTFE?

Tetrafluoroethylene propylene (FEPM, TFE/P), also known as Aflas®, is a partially fluorinated elastomeric polymer consisting of propylene and tetrafluoroethylene repeat units. Its thermo-physical properties are similar to those of polytetrafluoroethylene (PTFE) but somewhat inferior.

Is Aflas good for steam?

AFLAS® is highly resistant to a wide range of chemicals, such as acids, amines/bases and steam.
