Influence of thermal aging on properties of EPDM peroxide vulcanizates

Abstract

Aging of rubber is one of the decisive factors affecting the reliability and durability of the products. Evaluation of resistance to aging allows selecting the optimal formulation of rubber compounds and determining the warranty service and storage of rubber products. One of the most important factors determining the resistance to aging of rubber is the nature of the molecular chains of the polymer (a type of rubber). Research aimed at improving the process of sulfur vulcanization of EPDM rubber was carried out on the enterprise «Eurasian Industrial Technical Group» LLP since at present time the application of this technology is not possible due to the fact that the use of peroxide curing of rubbers is more economical.
