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.
What is the difference between EPDM and FKM?
EPDM (EP, EPR, Ethylene-Propylene Rubber) Both materials are well suited for use in the -30 to 150°C range. FKM has an advantage in lower temperatures and EPDM has an advantage in higher temperatures.
What is fluoroelastomer rubber?
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).
Is EPDM a fluoroelastomer?
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.
What is fluoroelastomer made of?
Is Viton and FKM the same?
Viton® is a trademark of a synthetic rubber and fluoropolymer elastomer commonly used in the manufacture of O-Rings. The name is a trademark registered by The Chemours Company and its international abbreviation is FPM (DIN/ISO denomination) or FKM (ASTM).
What is fluorosilicone rubber?
Fluorosilicone rubber offers the environmental stability inherent in dimethyl silicone elastomers, so it’s able to function under conditions that would literally destroy many conventional materials. SILASTIC™ Fluorosilicone Rubbers (FSRs) from Dow are silicone-based, highly fluorinated elastomers
What are the properties of Fluorosilicones?
This property provides excellent resistance to hydrocarbon fuels, petroleum oils and silicone fluids. Fluorosilicones provide a much wider operational temperature range than fluorocarbon (FKM) elastomers -70°F to 400°F (-57°C to 205°C).
What is fluorosilicone addition curing?
The addition curing of fluorosilicone, which produces no decomposition products, is one of the newest curing methods and is mostly used for liquid silicones. FVMQs offer good resistance to automotive and aviation oils, fuels and many other chemicals and solvents. As such, fluorosilicones are ideal for use in sealing technology.
What is the difference between VMQ and fluorosilicone rubber?
Fluorosilicone rubber differs from pure silicone rubber (VMQ) in that some of the methyl groups are replaced by trifluoropropyl groups. Such compounds combine the inherently good swelling resistance of fluorocarbon rubber (FPM) with the low-temperature flexibility of VMQ.
