Brief Introduce of Fluoroelastomer Fluoro Rubber

---Fluoroelastomer Fluoro Rubber are synthetic rubbers whose carbon atoms on their main chains or side chains are surrounded by fluorine atoms with strong electronegativity.
---As the energy of fluorocarbon bond is very high (fluorocarbon's bond energy is 485 kilo-joule/mol, which is equivalent to 116 kilo-calorie/mol), and fluorine atoms'covalent radis is light larger than oxygen atoms', rather the half length of carbon-carbon bonds, so fluorine atoms can mask carbon-carbon's main chain, which ensure the stability of carbon-carbon bonds.Therefore, Fluoroelastomer Fluoro Rubber possess many excellent properties which other synthetic rubber can not compare with.
---Rimpex could supply all kinds of Fluoroelastomer Fluoro Rubber, so that they can meet the demands of different producing process technique.
---The fluoroeladtomers are divided to non-vulcanized rubbers and vulcanized rubbers according to the depth of curing.
---Middle, low viscosity Fluoroelastomer Fluoro Rubber have good polymer rheologic properties, and they can not stick to materials when mixed.This is the most merit of Fluoroelastomer Fluoro Rubber which is thought highly by many buyer home and abroad.
