What is a rubber accelerator?

Rubber accelerators are substances that increase the speed of vulcanization, a process where rubber becomes more durable through the addition of sulfur at high temperatures. They play a pivotal role in reducing the curing time and improving the efficiency of the vulcanization process.

Which accelerators are suitable for natural rubber and synthetic rubber?

We supply both primary and secondary accelerators that are suitable for both for natural rubber and synthetic rubber compounds including NR, CR, SBR, NBR, BR, EPDM and chlorobutyl rubber. We offer a wide range of cure speeds from delayed action to ultra-accelerators.

Why are accelerators important in the rubber industry?

In the rubber industry, accelerators are crucial for enhancing production efficiency and product quality. They ensure uniform and faster vulcanization, resulting in rubber products that are more durable, resilient, and heat resistant.

What accelerator is used in vulcanization of rubber?

Sulfur is a common accelerator, but it is slow in the production of vulcanizates. The accelerator increases the rate of cross-linking between rubber molecules, shortening the vulcanization time. At the same time, it reduces the temperature. There are three main types of accelerators: sulfenamides, thiurams, and dithiocarbamates.

What is rubber vulcanization?

Vulcanization is a chemical process that involves treating rubber with sulfur at high temperatures to improve its properties. Rubber accelerators play a crucial role in this process by speeding up the reaction between rubber and sulfur, thus reducing the vulcanization time and making the process more efficient.

How to increase the speed of vulcanization of rubber?

Chemindustries offers full range of rubber accelerators to increase the speed of the vulcanization of rubber. We supply both primary and secondary accelerators that are suitable for both for natural rubber and synthetic rubber compounds including NR, CR, SBR, NBR, BR, EPDM and chlorobutyl rubber.
