Classification of rubber
There are many varieties of rubber, and the classification methods are not uniform.
1) According to the source of materials, it can be divided into two categories: Natural Rubber and Synthetic Rubber.
2) According to its performance and use, it can be divided into two categories: Universal Rubber and Specialty Rubber Eastomer.
* Any rubber with the same or close performance as natural rubber, good physical properties and processing properties, and can be widely used in tires and other general rubber products is called general rubber.
General rubber: natural rubber (NR), styrene butadiene rubber (SBR), butadiene rubber (polybutadiene rubber, BR), isoprene rubber (polyisoprene rubber, IR)
* Any special rubber product with special properties, special for heat resistance, cold resistance, chemical corrosion resistance, oil resistance, solvent resistance, radiation resistance, etc. is called special rubber.
Special rubbers include: nitrile rubber (NBR), silicone rubber, fluoro rubber, urethane rubber, polysulfide rubber, polyacrylate rubber (UR), chloroether rubber, chlorinated polyethylene rubber (CPE), chlorosulfonated polyethylene (CSM), butadiene rubber, etc.
In fact, there is no strict boundary between general rubber and special rubber. For example, ethylene propylene rubber has the above two characteristics. Between general rubber and special rubber are: neoprene (CR), ethylene propylene rubber (EPDM), butyl rubber (IIR)
