silicone rubber sheet . silicone is soft glossy & elastic rubber material resistant to high temperature of the order of up to 300 de gree celsius without fail. silicones are also available in food grade quality & thats the reason widely use in medical applications. fda approved thin food grade films are manufactured in clean & hygienic production rooms.
fkm / viton commercial grade fluoroelastomer sheet the selection of the most suitable viton rubber sheet to be used for any specific enduse implementation shall be determined by the enduse provider and in specific whether the detail of it must provide: acid resistance or base resistance to hydrocarbon liquids flexibility at high temperature holding seal at low temperature.
low temperature bases can improve performance to 40°f. new s being offered have improved chemical resistance and low temperature performance. fkm® extreme etp offers similar chemical compatibility as kalrez with temperature performance with a tr10 of 40°f and brittleness to 76°.
viton ® rubber sheets are widely used in:. industries of oil and gas; shipping especially oil tank power coalfire power station and nuclear station chemical engineering etc. whereby risks of corrosion and high temperature are major concerns.

currently 23 type viton fluorine rubber except strong acid resistance especially the fuming nitric acid has been employed 26 type fluorine rubber sheeting has been replaced many other occasions. in type 23 fkm fluorine rubber the fluorine content of vinyl chloride had a great influence on its performance.
fkm rubber properties: fkm rubber contains strong carbonfluorine bonds giving it high chemical thermal and oxidation resistance. fkm contains varying amounts of carbonhydrogen bonds a weak link for heat and chemical resistance but is still more chemically resistant than most other elastomers. 11
fkm / viton.fkm has excellent resistance to high temperature oil solvent flame chemical and weather and it is usually applied in automotive chemical processing aerospace and many industrials. viton glt is broadly used in thermal range of 40to +250and it has outstanding resistance to aggressive htstype oils which are commonly used in
the service temperature range is from 40° f to +400° f but resistance to compression set is poor at high temperature. the molding process results in an integral single sheet of microcellular foam with a thin slightly denser skin on each surface.
fluoroelastomer sheet rubber. all of our fluoroelastomer fkm products are manufactured with fkm fluoroelastomer sourced from the world's leading manufacturers. fluoroelastomers were originally introduced over 50 years ago to meet the needs of the aerospace industry for a highperformance elastomer.
polycomp fkm rubber compounds. fkm rubber compounds. fkm rubber compounds. fkm advantages ;the chemical resistance and high temperature stability is due to the bulkiness of the fluorine atoms shielding the backbone and carbonfluor bond from attack and the high bonding energy of the carbonfluor bond as illustrated in the
viton rubber is a highperformance rubber that has an excellent resistance to many acids chlorinated fuels and hydrocarbons. specific gasket sheet properties should be taken into account before use in the gas and oil industry. these properties include hardness thickness and
1. specifications of pure fkm rubber gasket sheet. 1. fluorine rubber or fkm is based on hexafluoropropylene vinylidene fluoride. 2. temperature range 30 centigrade to +250 centigrade.good resistance to most chemicals and industrial fluids will retain strength and withstand embrittlement during longterm heat exposure.
contains 66 percent fluorine and is a co of vinylidene fluoride vf2 or vdf andlow temperature resistance also varies based on the fluorocarbon type as shown in figure 2.4military specification mil r 83248 has the full title rubber fluorocarbon elastomer high temperature fluid and compression set resistance.
ffkms by astm 1418 standard equivalent to ffpms by iso/din 1629 standard are perfluoroelastomeric compounds containing an even higher amount of fluoride than fkm. they have further improved resistance to high temperatures and chemicals and even withstand environments where oxygenplasma are present for many hours. certain grades have a maximum continuous service
viton fluorine rubber has the increase of compression permanent deformation at high temperature it is due to the high temperature and the result of joint action. in general the compression permanent deformation is related to molecular mass of the rubber vulcanizing and acid absorption agent type and secondary vulcanization conditions.

fluroelastomer or fkm is a class of synthetic rubber designed for very high temperature operation. fkm provides extraordinary levels of resistance to chemicals
aggressive environments or high temperatures. fkm fluorocarbon rubber depending on structure and fluorine content fkm materials can differ with regards to their chemical resistance and coldflexibility. fkm is known especially for its nonflammability low gas permeability and excellent resistance to ozone weathering and aging.
viton b rubber sheetpremium 70 duro heat resistant chemical resistant fuel & oil resistant viton rubber. reglin viton b rubber is a black grade 70 duro fluoroelastomer sheet which has very high temperature and chemical resistance to acids and alkalis.
fkm rubber is highly resistant to high temperatures up to +250°c. however they arent as suited to cold temperatures as other rubber compounds with 10°c being the minimum functioning temperature. despite fkm sheeting having high resistance to hydrocarbons oils acids and chemicals it cannot be used where resistance to ketones is required.
