What are primary and secondary accelerators in rubber compounding?

In rubber compounding, primary accelerators and secondary accelerators are two types of accelerators used to speed up the vulcanization process. Here’s a comparison between them: Function: Primary accelerators are responsible for initiating and promoting the initial stages of vulcanization. They provide fast initial curing rates.

How do I choose a rubber accelerator system?

When selecting an accelerator system for the production of a specific rubber product, it is essential to consider the following factors: The accelerator system should demonstrate effectiveness across a broad spectrum of cure temperatures and exhibit compatibility with different types of polymers.

How to choose an effective acceleration system in compounding?

Choosing an effective acceleration system poses a challenging task in compounding. The selected system must have good stability in raw stock storage and a delay period before vulcanization begins, allowing efficient mixing and processing. It should be compatible with the chosen curing method.
