For the production of fluororubber:Fluoroelastomer (FKM) is a synthetic polymer elastomer containing fluorine atoms on the carbon atoms of the main chain or side chain.

Hexafluoropropylene (HFP) is one of the basic raw materials of organic fluorine industry. Its importance is second only to that of tetrafluoroethylene.

Sodium borohydride is a kind of inorganic substance, chemical formula is NaBH4, white to gray white fine crystalline powder or block, hygroscopic strong, its alkaline solution is brownish yellow, is one of the most commonly used reductants. Soluble in water, liquid ammonia, amines. Soluble in meth

Furfural, also known as 2-furfuraldehyde, is the same substance as glycoaldehydes. Its scientific name is α-furaldehyde, which is a derivative of hydrogen atom substituted by aldehyde group on furan 2 site. It is originally made from rice bran coheated with dilute acid, so it is called furfural.

Hexafluoropropylene,is an organic compound with the structural formula CF3CF=CF2. It is odorless and colorless gas. The melting point is -156.2°C, and the boiling point is -30.5°C. The relative density is 1.583 (-40℃/4℃). Slightly soluble in ethanol and ether. Used as raw materials for fluororubber,
