accelerator: an accelerator is a material that, when mixed with a catalyst and resin, speeds up the chemical reaction between the catalyst and the resin (usually in the polymerizing of resin or vulcanization of rubbers). accelerators are also known as promoters when used with polyester resins and vulcanizing agents when used with rubbers.

- How vulcanization accelerator is used in rubber goods manufacture?
- CBS is exclusively used as vulcanization accelerator in rubber goods manufacture. Vulcanization transforms the rubber from the thermoplastic into the elastomeric state at temperatures between 150 and 200 °C. CBS is loaded to the rubber in concentrations of 0.5– 1% (ww) but it breaks down during the curing process.
- Is CBS a rubber accelerator?
- Almost all rubber compounds on the market contain rubber accelerator as CBS in a wide range of products, but it is difficult to know which rubber product contain which rubber accelerants. Therefore the use of CBS in consumer product cannot be ruled out completely.
- Is dixp a good accelerator for carboxylated nitrile latex?
- It is also an effective accelerator for carboxylated nitrile latex, when used in combination with NaMBT. The advantages pf this system are: Since DIXP does not contain nitrogen in its chemical structure, it cannot produce N-nitrosamines.
- Why are accelerators used in vulcanizing elastomers?
- Accelerators are added in small amounts to speed up the curing of adhesives by reducing the cure time and temperature of elastomers, particularly latex systems. The selection of an accelerator will depend on the specific vulcanizing system and curing properties.
