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.
