low price CAS 10591-85-2 Rubber Vulcanizing Accelerator for rubber curing process
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.

Accelerant
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.

The continuous vulcanization in liquid baths is called LCM (liquid curing method).In this process, the extrudate is run through a suitable hot bath immediately after leaving the extruder. The bath temperature is usually 200-300 degrees Celsius consisting of salt mixtures, polyglycols, silicone oil and metal alloys.

Vulcanization & Accelerators
Vulcanization of rubbers by sulfur alone is an extremely slow and inefficient process. The chemical reaction between sulfur and the Rubber Hydrocarbon occurs mainly aC (doublet the C = bonds ) and each crosslink requires 40 to 55 sulphur atoms (in the absence of accelerator). The process takes around 6 hours at 140°C

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 (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.
