| Material | Base Rubber | Vulcanization System | Reinforcing and Filling System | Softening and Plasticizing System | Protection System |
| Nitrile Butadiene Rubber (NBR) | Copolymerized from butadiene and acrylonitrile | Usually uses sulfur and sulfur-containing compounds as vulcanizing agents, and peroxides or resins can also be used. To obtain low compression set, it mostly adopts the combination of low sulfur and sulfur-containing compounds, or a sulfur-free vulcanization system and a peroxide vulcanization system. | Commonly used reinforcing agents include semi-reinforcing carbon black, super abrasion-resistant carbon black, high abrasion-resistant carbon black, etc.; filling agents can be calcium carbonate, clay, etc. | Commonly used plasticizers include dibutyl phthalate, dioctyl phthalate, etc. | Various antioxidants are added according to product performance and usage conditions, such as antioxidant D, antioxidant 4010, etc. |
| Chloroprene Rubber (CR) | Polymerized from chloroprene monomer by emulsion polymerization | Generally uses magnesium oxide, zinc oxide, etc. as vulcanizing agents, and cooperates with accelerators for vulcanization. | Commonly used reinforcing agents include high abrasion-resistant carbon black, semi-reinforcing carbon black, etc.; filling agents can be calcium carbonate, clay, etc. | Commonly used plasticizers include dibutyl phthalate, tricresyl phosphate, etc. | Antioxidants are usually added, such as antioxidant D, antioxidant 4010, etc. |
| Ethylene Propylene Diene Monomer (EPDM) | Copolymerized from ethylene, propylene and a small amount of non-conjugated diene | Generally adopts a peroxide vulcanization system, and a sulfur vulcanization system can also be used. EPDM vulcanized by peroxide has better heat resistance and compression set performance. | Commonly used reinforcing agents include carbon black, white carbon black, etc.; filling agents can be calcium carbonate, talcum powder, etc. | Commonly used plasticizers include paraffin oil, naphthenic oil, etc. | Antioxidants are usually added, such as antioxidant MB, antioxidant 4010NA, etc. |
| Fluoroelastomer (FKM) | Polymerized from fluorine-containing monomers | Generally uses amine-based vulcanizing agents, bisphenol AF vulcanizing agents, etc. for vulcanization. | Commonly used reinforcing agents include carbon black, white carbon black, etc.; filling agents can be calcium carbonate, barium sulfate, etc. | Commonly used plasticizers include fluorocarbon oil, perfluoropolyether, etc. | Antioxidants are usually added, such as antioxidant D, antioxidant 4010, etc. |
