It is the main vulcanizing agent for rubber various accelerator masterbatches from China factory. The product is more soluble in natural rubber and styrene-butadiene rubber at room temperature, but less soluble in regular polybutadiene rubber and butadiene-cyanogen rubber with the increase of temperature in the rubber solubility increased. The product is filtered through a sieve and mixed with a filter machine to remove the agglomerates and crystals in the sulfur powder, improve the performance of the product and reduce the production of defective products and waste products.

Rubber is a synthetic polymer consisting of long chains of linear or branched molecules that are chemically cross-linked. Rubber accelerators are substances that accelerate the polymerization of other monomers, allowing for the production of high-performance materials with a wide range of applications.
Rubber accelerators can be used to speed up the production of polymers such as rubber and polyester. They also improve the properties and toughness of plastics and rubber, as well as fibers. The properties that are improved by using an accelerator are:
• Stronger than normal (so they can maintain their shape longer)
• Stretchier and more elastic
• Tougher and less brittle than normal (depending on the material)
Rubber accelerators are often found in tools, tires, gaskets, cables, pipe fittings, industrial machinery, plastic parts for cars and airplanes, etc.
A rubber accelerator is an accelerator compound consisting of an organic polymer and a rubber (or other latex) additive. The polymer is a modified version of the organic elastomer normally added to resins to increase the tackiness of the resin; the rubber is simply added for lubricity, strength, or to form a more flexible product. These are typically used in composite materials with rubber as the main component. Some rubber accelerators may also be used in plastics with rubber additives such as acrylonitrile butadiene styrene copolymer (ABS), polyvinyl chloride (PVC), polyurethane (PU), ethylene vinyl acetate (EVA); these are known as plasticizers.
The increased tackiness of rubber accelerators is achieved by several mechanisms:
As a result, different types of rubber accelerators are preferred for different applications. Rubber accelerators can be made from natural rubbers (such as natural rubber, butadiene-butadiene rubbers, and acrylonitrile-butadiene-styrene rubbers) and synthetic rubbers such as nylon 652; they can also be made from modified plasticizers or other additives such as chemicals such as urea and acetic acid. While most accelerated compounds have found their way into automotive tires through tire inflation additives, rubber accelerators have also been developed for many other applications including cushioning materials like PFK (polyetheretherketone) for automobile seats and seat belts, medical implant materials like nanofoam for artificial joints in orthopedic devices, sports equipment like foam trainers for high jumpers and volleyball players; chemical accelerators have been used to increase chemical stability of chemical corporations against microbial attack; heat stabilizing agents have been used to convert heat energy into electrical energy; corrosion inhibitors have been employed in chemical processing plants to make them resistant to corrosive environments; and so on.
Rubber accelerators have been around for years, but they have only recently started to become more widely used. The first rubber accelerators were developed in the 1960s, and rediscovered in the 1980s. They were originally used for controlling viscous flow of fluids, but since the 1990s we have found that they also work very well in many other applications:
