What is FKM (Viton®)?

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.

What is FVMQ

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.

What is VMQ?

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:

What is NBR (Nitrile butadiene rubber) ?

NBR (Nitrile butadiene rubber), in short nitrile rubber, is also known under the trade names Nitrile®, Perbunan® and BUNA-N®. It is an elastomer, a synthetic polymer obtained by the copolymerization of acrylonitrile and 1,3-butadiene. It is a “random” copolymer, that is, the order of the acrylonitrile and butadiene groups in the polymer chain is unordered.
