(B) Viability of HaCaT, HGF‐1, SCC25, and Ca9‐22 cells measured via MTT assay and shown after treatment with different concentrations of BR for 24
Chemical accelerators are used in glove manufacturing to hasten the linkage of molecules in natural rubber latex or in synthetic rubber latex like nitrile and vinyl. The accelerants transform the liquid materials into thin, strong, and elastic glove films. Sulfur-based chemical accelerators include dithiocarbamates, thiurams, and
Vulcanization of Rubber Matmatch
Vulcanization is a chemical process in which elastomeric materials are heated with an agent (generally sulfur), an activator, an accelerator, and sometimes a retarder to form a cross-linked molecular network. This results in improved properties such as elasticity, resilience, tensile strength, viscosity, hardness, and weather resistance [3]. 1.

RUBBER PROCESSING TECHNOLOGY
•Natural rubber is tapped from rubber trees (Hevea brasiliensis) as latex The trees are grown on plantations in Southeast Asia and other parts of the world •Latex is a colloidal dispersion of solid particles of the polymer polyisoprene in water Polyisoprene (C 5 H 8) n is the chemical substance that comprises rubber, and its content in the

RUBBER TECHNOLOGY: Ingredients, Activators, Fillers
Accelerator Activators. Inorganic compounds mainly metal oxides-zinc oxide, hydrated lime. Organic Acids Normally in combination with metal oxides. Stearic, oleic. Alkaline substances will increase ph of rubber. Usually increases cure rate. Age Resistors (Antidegredants) All rubbers are affected by aging.
WESTCO™ DCBS is a slow curing, delayed action accelerator especially useful in curing thick rubber parts. WESTCO™ DETU Accelerator WESTCO™ DETU is an ultra accelerator for CR, EPDM and chlorobutyl rubber; it is also used in latex as a
