Accelerators

Vulcanisation is the process of cross-linking rubber molecules into a three-dimensional network of chains. However, vulcanisation of rubbers with sulphur alone is slow. Therefore, accelerators are added to the rubber mixture to increase the vulcanisation speed and allow vulcanisation to proceed at lower temperature and with higher efficiency. Accelerators are usually added to the rubber mixture at the raw material stage. The amount used varies depending on the desired vulcanisation time, temperature and type of rubber.

The correct selection and use of accelerators is important for optimising the vulcanisation process and improving the quality of rubber products. Most accelerators are organic substances containing nitrogen or sulphur or both. Accelerators are classified as Primary or Secondary accelerators according to the role they play during the process.

Benefits of Accelerators

• Shortens vulcanisation time.
• Allows vulcanisation at lower temperatures.
• Makes the vulcanising process more efficient.
• Improves the mechanical properties of rubber.
