FFKM (Kalrez ring) perfluorine-rubber material is the best rubber material with high temperature resistance, strong acid and alkali resistance and organic solvent resistance among all elastic sealing materials at present. Perfluorinated rubber can resist the corrosion of more than 1600 chemical solvents such as strong acid, strong base, organic solvent, ultra-high temperature steam, ether, ketone, ester, nitrogen compounds, hydrogen carbide, alcohols, aldehydes, furan and amine compounds. High temperature resistance up to 320℃. FFKM has nearly 40 years of experience with perflurane seals in a variety of industries. Lanhe seal ring are manufactured to AS-568 (USA), DIN-3771 (Germany), BS-1806 (UK), ISO3601 (International), JIS-B2401 (Japan) and other standards, or can be customized to your specific size.

Polyurethane rubber can be mixed into two categories, one is polyester polyurethane (AU), the other is polyether polyurethane (EU). AU type has excellent oil, fuel and solvent resistance, but is susceptible to hydrolysis, EU type is not susceptible to hydrolysis, and has considerable fuel and oil resistance compared to low acrylonitrile (18-22% ACN) nitrile butadiene rubber or HNBR. Compared with other elastomers, PU oring made of polyurethane rubber has excellent wear resistance, high tensile strength and high elasticity.

FVMQ FLuorosilicone Rubber Gaskets
FVMQ FLuorosilicone Rubber Gaskets:Fluorosilicone rubber is called FVMQ,FluoroSilicone rubber provide chemical properties similar to those of fluorinated organic elastomers. 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). Many applications for fluorosilicones are in synthetic oils, gasoline and even extended fuels since its low temperature performance is much better than that of FKM’s.Features: • Excellent flexibility and resistance to compression set • Excellent resistance to aging and weather-sunlight • Resistance to oxidizing chemicals, animal and vegetable oils, fuels, aromatic and chlorinated solvents • Resistant to diluted alkalies, diester oils, aliphatic and aromatic fluorocarbons, silicone oil, toluene, benzene, ozone and oxidative environments.Limitations:• Brake fluids, ketones, hydrazine, adelhydes, amines, ketones• Poor abrasion resistanceAvailable In: 1.Full Rolls 2. Cut to strip 3.Bespoke GasketsLANHE SEALS produces FVMQ gaskets,FluoroSilicone rubber sheet, FluoroSilicone O-Rings and other rubber sealing products. FVMQ are made of fluorosilicone or fluorinated silicone rubber. Regular Silicone gaskets should not be used with substances that include oil or petroleum. Fluorosilicone seals is then used in this situation. For more fluoro-silicon products, please contact LANHE SEALS.

FKM (by ASTM D1418 standard) (equivalent to FPM by ISO/DIN 1629 standard) is the designation for about 80% of fluoroelastomers as defined in ASTM D1418.Fluorocarbon rubber is the most significant single elastomer. Highly fluorinated carbon-based polymers used in applications to resist harsh chemical and ozone attack. The name Viton ® is trademark of Dupont.

luoresilicone combines the good properties of high and low temperature of silicone with limited resistance to fuel and oil. In fact, it is a plastic because of the lack of hydrocarbon compounds. Fluoresilicone is available in all different RAL colours, as well as transparent. The colouring of fluorosilicones does not affect the mechanical properties. The maximum temperature resistance goes up to 230ºC and the material is very plastic, from hard (80 Shore-A) to soft (40 Shore-A). Fluorosilicones offer a much wider range of temperatures under freezing temperatures than Fluorocarbon rubbers. The most important applications of fluorosilicon seals are cooling & freezing systems, arctic conditions, but also in fuel systems at temperatures up to + 177 ° C (+ 350 ° F) and in applications where the dry heat resistance of silicone O-rings is required.Fluorine silicone seals can also be exposed to oil based on petroleum and / or hydrocarbon fuels. In contrast to silicone, fluorosilicones are resistant to silicone oil & grease.

For a number of sealing solutionswe use VMQ, which is also available as LSR (Liquid Silicone Rubber) material. But what exactly is a VMQ or LSR material? Silicone (VMQ) is a group of elastomers made from silicon, oxygen, hydrogen and carbon. The characteristics of silicone compounds (VMQ) are:
