Chapter 4: Activators and Accelerators These chemicals are used to enhance the vulcanizing process. The first accelerators used were materials based on inorganic chemicals. They included basic Lead Carbonate, Lime, Magnesia, and litharge. Inorganic accelerators remained the most important type for many years.

Jan 1, 2017 · Activators are inorganic and organic chemicals used to activate the action of accelerators. These materials reduce the vulcanization time (cure time) by increasing the rate of vulcanization. Zinc oxide is generally used in combination with a fatty acid (stearic acid) to form an in situ rubber soluble soap–zinc stearate in the rubber matrix.

ADP, on the other hand, serves as a positive allosteric regulator (an allosteric activator) for some of the same enzymes that are inhibited by ATP. For instance, ADP may act by binding to an enzyme and changing its shape so that it becomes more active. 7 ^{7} 7 start superscript, 7, end superscript

Accelerators (Chapter 4) - Particle Detectors

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.
