Classification methods and types of rubber

Now many kinds of rubber, according to different classification methods, there are different categories, the main use of the current source and use of chemical structure and classification methods.
Classification of sources:
Natural rubber;
Synthetic rubber:
1 general rubber, styrene butadiene rubber, butadiene rubber, butyl rubber, nitrile rubber, chloroprene rubber, butyl rubber, EPDM rubber;
2 specialty rubber: fluorine rubber, acrylic rubber, chlorinated polyethylene, chlorinated polyethylene, ethylene acrylic acid methyl ester, silicone rubber, polyurethane rubber, polyether rubber, polyurethane rubber by the chemical structure:
Carbon chain rubber:
1 unsaturated non polarity: NR, SBR, BR, IR
2 unsaturated polarity: NBR, CR
3 saturated non polarity: EPM, EPDM, IIR
4 saturation polarity: FPM.ACM, ANM, CSM, CPE, AEM
Two: miscellaneous chain rubber: Q, AU, EU, CO, ECO, GPO, GPO, T.,
If the raw form can also be divided into solid, powder, viscous liquid, latex in four forms.
According to the way of crosslinking, it is divided into the traditional thermoplastic rubber and thermoplastic elastomer.
, of course, the varieties, because of the Mooney viscosity, monomer in copolymer, polymerization method, bonding and structure different, whether pollution, oil filled, filled with carbon black, whether there is vulcanization unit, whether there is a chemical modification has produced many sub types and different grades.
