Why use antioxidants in rubber products?

The vulcanization of rubber, whether natural or synthetic, requires the use of accelerators, sulfur donors and activators for different reasons: To optimize and control vulcanization, in order to improve the performance of finished products , and sometimes, partially or totally replacing the sulfur in so-called “efficient” or “semi-efficient” systems.

Depending on the impact on the vulcanization rate, accelerators are categorized as follows:

“Slow” accelerators (guanidines)
“Fast” accelerators (sulfenamides or thiazoles)
“Very fast” accelerators (thiurams or carbamates)
To achieve the right compromise between the kinetics of vulcanization, the processing and the physico-chemical properties of the finished product, our specialists will guide you to find the appropriate combination between the various accelerators, activators and sulfur donors.

Antioxidant H: Protect your product
Rubber parts need more or less protection against the effects of external factors that increase aging. These factors are diverse: oxidizing agents (such as oxygen), agents increasing the rate of oxidation (such as heavy metals), ozone, UV rays, heat, mechanical stresses, chemicals ...
