NewsWhat is FKM? The term FKM stands for fluoroelastomer. This type of material was developed during world war II as an antidote to the leaking nitrile seals that plagued the aircraft of the era. Fluorinated polymers that were developed as a solution for this matter contained chemically inert fluorine-carbon bonds that deliver a combination of temperature performance and a high chemical resistance. There are two major types of FKM as FKM type 1 and type

NewsElastomer O-ring seals are commonly used to provide demountable vacuum seals. The proper choice of material, installation, and handling are key to a successful vacuum design. The sealing integrity of vacuum systems is, undeniably, a crucial aspect of vacuum technology, and demountable seals are an important segment. A demountable seal can be considered to be any seal that is capable of being opened or closed as opposed to permanent seals such as welded or brazed

NewsSelecting the right FKM grade while designing or creating a new specification is very important to ensure you get the right seals every time. A brief survey of FKM grades and their physical properties reveals various strengths for various applications. If you are not from the polymer background, it is likely that you associate FKM with the name “Viton.” Viton is the DuPont brand name for its range Of Fluoroelastomers. However, there are other leading

Newsfluoroelastomer, 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). These fluorinated elastomers have outstanding resistance to oxygen, ozone, and heat and to swelling by oils, chlorinated solvent, and fuels. Fluoroelastomers were developed in the 1940s and 1950s after the discovery at E.I. du Pont de Nemours & Company (now DuPont Company) of the heat-resistant resin polytetrafluoroethylene,
