Vulcanization an overview ScienceDirect Topics
Vulcanization. Vulcanization is a chemical process in which the rubber is heated with sulphur, accelerator and activator at 140–160°C. The process involves the formation of cross-links between long rubber molecules so as to achieve improved elasticity, resilience, tensile strength, viscosity, hardness and weather resistance.
Global leader in vibration control, fluid management and sealing system technologies based on rubber, thermoplastic, elastomeric and polymer materials.

Accelerants are substances that can bond, mix or disturb another substance and cause an increase in the speed of a natural, or artificial chemical process. Accelerants play a major role in chemistry—most chemical reactions can be hastened with an accelerant. Accelerants alter a chemical bond, speed up a chemical process, or bring organisms back to homeostasis.
- Is Cz a good accelerator?
- CZ is a medium fast primary accelerator, suitable for NR, IR, SBR, NBR, HR and EPDM. Also an outstanding delayed action accelerator. Be top effective and safe when used at ordinary processing temperatures, cause no scorches. Vulcanized show excellent physical property and quickly complete. Usually used alone when activated by DPG, TMTD and TMTM.
- What are the benefits of a CBS accelerator for vulcanization?
- CBS is particularly effective in promoting the cross-linking of natural rubber and synthetic rubbers such as SBR, NBR, and EPDM. It is also compatible with other accelerators such as MBTS and TBBS, which can improve the efficiency of the vulcanization process.
- How does CBS work in rubber vulcanization?
- CBS is a thiazole-based accelerator that promotes the formation of sulfur cross-links between rubber molecules during vulcanization. It works by reacting with the sulfur and forming a complex that facilitates the cross-linking process. This results in a more stable and durable rubber product.
- What type of accelerator is used in vulcanization?
- Primary accelerator: this group of accelerators usually have a long burning time and are quickly cooked in the main stage of vulcanization Polymer accelerators are used to produce various types of rubber such as isoprene, styrene, butadiene and NBR. Sulfonamides are one of the most popular primary accelerators.
