vulcanization accelerators

Vulcanization Accelerators

Vulcanization of rubber by sulfur alone is an extremely slow process and can take several hours at elevated temperature (140°C or more). This is problematic becasue long exposure to temperature and oxygen leads to oxidative degradation which, in turn, results in poor mechanical properties.

EPDM compounds have much less cure sites than natural rubber or SBR, and therefore need a rapid vulcanization system to have sufficient cure speed. Latex is cured at relatively low temperature (100- 120 °C)and therefore need an inherently rapid accelerator.

Vulcanization - an overview | ScienceDirect Topics

Vulcanization. Vulcanization is a chemical process in which the rubber is heated with sulphur, accelerator and activator at 140–160°C. The process involves the formation of cross-links between long rubber molecules so as to achieve improved elasticity, resilience, tensile strength, viscosity, hardness and weather resistance.

Difference Between Vulcanized and Unvulcanized Rubber

What is Vulcanized Rubber. Rubber that has undergone the process of vulcanization is called vulcanized rubber. During the process of vulcanization, chemical bonds are formed between the independent polymer chains of a particular rubber, resulting in a molecular network within the polymer matrix. These new chemical bonds are often called cross

vulcanization

Vulcanization

Vulcanization (British: Vulcanisation) refers to a range of processes for hardening rubbers. The term originally referred exclusively to the treatment of natural rubber with sulfur, which remains the most common practice; however, it has also grown to include the hardening of other (synthetic) rubbers via various means.
