What is a Fluoroelastomer?

Fluoroelastomers are fluorinated synthetic polymers designed for harsh environments including aggressive chemical and temperature applications. These materials are sometimes referred to as Viton®, which is a registered trademark of DuPont Performance Elastomers. J-Flex is an official licensee within the "Genuine Viton" programme.

Other suppliers of Fluoroelastomer polymer are Dyneon; Solvay and Daikin. Fluoroelastomer compounds are based on polymer that takes advantage of the high strength of the fluorine to carbon bond and the high ratio of fluorine to hydrogen. This unique chemistry and proper compounding means that some fluoroelastomer materials can perform continuously in temperatures of 204C and 300C intermittently.

The ASTM D2000 designation for fluoroelastomers is HK meaning the highest heat resistance and the lowest swell available of rubber type elastomers. More.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
