What is FVMQ material?
FVMQ (Fluorosilicone) combines the good high- and low-temperature properties of silicone with limited fuel and oil resistance. Fluorosilicones provide a much wider operational temperature range than Fluorocarbon rubbers.
What is the difference between fluorosilicone and silicone?
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.
What is fluorosilicone used for?
The unique properties of fluorosilicone make it a problem-solving material that widely used in industrial, aerospace, automotive and aviation applications for static sealing and cushioning.
Is fluorosilicone an elastomer?
Fluorosilicone (FVMQ) is an elastomer made up from a silicone polymer chain with fluorinated side-chains. This structure provides the elastomer with a number of qualities that make it the perfect choice of material for the aviation industry.
Is fluorosilicone fungus resistance?
50 durometer fluorosilicone is fungus resistant and takes a low compression set.
Is fluorosilicone conductive?
Fluorosilicone – Fluorosilicone Sponge, Solid Fluorosilicone, Electrically Conductive Fluorosilicone. Fluorosilicone (FVMQ) is fluorinated version of silicone which gives this polymer superior chemical resistance.
What is the difference between silicone and fluoroelastomer?
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 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®)
| General Information | ||
|---|---|---|
| Short Name | Fluorosilicone: Fluorosilicone | FKM: FKM |
Is EPDM rubber fungus resistant?
Generally, EPDM(ethylene propylene) and Neoprene(chloroprene) are the polymers that we see utilized for fungus resistance in the gasketing industry.
Is silicone rubber expensive?
Is Silicone Rubber Expensive? Silicone rubber is more expensive than other synthetic and natural rubber variations due to its superior thermal stability and environmental resistance as well as its lengthy production process.
What is fluoroelastomer made of?
fluoroelastomer, also called fluorocarbon elastomer, any of a number of synthetic rubbers made by copolymerizing various combinations of vinylidene fluoride (CH2=CF2), hexafluoropropylene (CF2=CFCF3), chlorotrifluoroethylene (CF2=CFCl), and tetrafluoroethylene (C2=F4).
What temperature can EPDM withstand?
When compared with silicone rubber, EPDM is significantly inferior with a maximum temperature of 130°C (266°F).
What causes EPDM to swell?
EPDM is a hydrocarbon polymer, which swells excessively in hydrocarbon fluids such as mineral oils and hydrocarbon fuels, because of lack of polar groups in the polymer chain.
What is the difference between silicone and silicone rubber?
Natural rubber, with the chemical name polyisopropene, is produced naturally from the sap of the rubber tree. Silicone, on the other hand, is a synthetic material….Silicone vs Natural Rubber.
| Natural Rubber | Silicone |
