Precautions for using vulcanizing agents - China-Rubber Hose|Industrial
Vulcanization is an important part of rubber production and processing. In order to achieve the best vulcanization effect, it is necessary to use a vulcanizing agent reasonably. As a professional rubber processing manufacturer, we will introduce the precautions for using vulcanizing agents.

Use of vulcanizing Accelerator Aug 16, 2017 Rubber promoter is natural rubber, cis-butyl rubber, isoprene rubber, butyl benzene gum and regeneration of the residual promoter of rubber, usually used in the manufacture of cables, blankets, rubber shoes, inner tubes, colourful products, etc., especially suitable for alkali-containing strong carbon
About Vulcanizing Agents,Accelerators and Activators
Vulcanizing Agents,Accelerators and Activators During vulcanization, the long chain of the rubber molecules become crosslinked by reactions with the vulcanizing agent to form three-dimensional structures. In pratice, BIPB is used almost exclusively for vulcanization of rubber.

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.
Vulcanization & Accelerators
Vulcanization & Accelerators Vulcanization is a cross linking process in which individual molecules of rubber (polymer) are converted into a three dimensional network of interconnected (polymer) chains through chemical cross links(of sulfur). The vulcanization process was discovered in 1839 and the individuals responsible for this discovery were

2. TAIC is available as co-vulcanizing agent for ethylene-propylene rubber, fluorine rubber, CPE and other special rubber (with DCP and the amount is 0.5 to 4% by weight), can significantly shorten the curing time,improve strength, abrasion resistance, insoluble, corrosion resistance. 3.
Vulcanization
Vulcanization (British: vulcanisation) is a chemical process, invented by Charles Goodyear, used to harden rubber. Vulcanization traditionally referred to the treatment of natural rubber with sulfur and this remains the most common example, however the term has also grown to include the hardening of other (synthetic) rubbers via various means.

It is a widely used building block and chemical reagent in the synthesis of organic compounds, including pharmaceuticals. It is used as a solvent and as a base. A significant industrial application of piperidine is for the production of dipiperidinyl dithiuram tetrasulfide, which is used as a rubber vulcanization accelerator.

The manufacturer sells said "vulcanizing solution" in quantities of 25g tubes through 1 gallon cans, so you should be able to buy it in larger quantities. Indeed, a quick search of Amazon yield 8 oz cans (or slightly cheaper), and while I couldn't find it on something well known like Amazon there are other places that sell the 1 gallon quantity.

Vulcanization
By far the most common vulcanizing methods depend on sulfur. Sulfur, by itself, is a slow vulcanizing agent and does not vulcanize synthetic polyolefins. Accelerated vulcanization is carried out using various compounds that modify the kinetics of crosslinking, this mixture is often referred to as
Accelerant
The use of accelerators and activators lowers the activation energy of vulcanization reaction to 80-125kJ/mole from 210kJ/mole which is necessary if we use sulfur alone. Accelerators and activators break sulfur chains. Accelerated sulfur vulcanization systems require only 5-15 sulfur atoms per cross-link as compared to 40-45 S atoms/crosslink for a non-accelerated sulfur vulcanization.
