Vulcanization & Accelerators
widely used accelerators in the rubber industry for the production of wide variety of goods such as cycle tyres and tubes, footwear, beltings, hoses and other moulded and extruded goods. Thiazoles are activated by Zinc oxide / Stearic acid combination and produce flat cure with vulcanizates having
The rubber blend is widely used in industry because of its excellent properties. In this study, Nitrile Butadiene Rubber (NBR) was blended with

Rubber Accelerators. Western Reserve Chemical offers a full range of rubber accelerators to increase the speed of the vulcanization of rubber. We supply both primary and secondary accelerators that are suitable for both for natural rubber and synthetic rubber compounds including NR, CR, SBR, NBR, BR, EPDM and chlorobutyl rubber.
Uses: Accicure DPG is used (normally in the range 0.50.3 phr dosages) as a secondary accelerator in combination with thiazoles and sulphenamides. Such combinations give fast cures and a high level of physicals with good modulus and are very popular for footwear & cables, etc.

G. Guanidines are an important class of vulcanization accelerators. The only two guanidines that are used on a commercial scale are diphenyl guanidine (DPG) and N, N'-diorthotolyl guanidine (DOTG). Both have a rather slow cure rate and require the use of zinc oxide for activation. They are a good choice for thick-walled rubber products.
dibenzyldithiocarbamate) are also frequent rubber allergens. Diphenylguanidine (DPG) is a rubber chemical accelerator and commonly used in polyisoprene gloves to improve the tensile strength of the final film. Carba mix is a screening allergen included in many baseline patch test series to detect dithiocrabamate and DPG allergies. Carba mix

TiBTD is a green and non-staining ultra-accelerator. Ot is widely used as accelerator for NR,IR,BR,SBR,IIR,NBR and EPDM vulcanization that almost not produce nitrosamine. The performance of TiBTD is similar with TT and TETD, but has no foaming risk. The good scorch protection combine with good cure time of TiBTD allows higher processing and

- Does DPG increase aging resistance of rubber?
- Moreover, Ahsan et al. reported that DPG used to activate other accelerators imparted the high aging resistance of rubbers. ... ... Natural rubber (NR) compounds can be cross-linked by sulfur (vulcanization), peroxides (cure), or sulfur donor accelerators, such as tetramethylthiuram (TMTD).
- What are the characteristics of DPG rubber?
- 2. Characteristics of DPG: - Acceleration: DPG functions as a medium-fast primary accelerator, meaning it promotes the vulcanization process in rubber production. - Moderate reactivity: It offers a balanced level of reactivity, making it suitable for a wide range of rubber types, including natural rubber (NR), synthetic rubber, and blends.
- How does vulcanization affect the performance of rubber products?
- Vulcanization, as the key step in rubber process，directly affects the processing and performance of rubber products. Compared with sulfur alone, the presence of small amounts of accelerator together with sulfur can significantly improve the properties of final vulcanisate.
- Is DPG a good accelerator for aging elastomers?
- The better resistance on the thermo-oxidative aging of elastomers cured with DPG as compared to other accelerators was reported by Travas-Sejdic et al. for NR vulcanizates. Moreover, Ahsan et al. reported that DPG used to activate other accelerators imparted the high aging resistance of rubbers. ... ...
- Should rubber vulcanization accelerators be discontinued?
- With the rapid growth in global demand for rubber products, the safety and environmental concerns of rubber vulcanization accelerators are becoming more prominent, and many countries have decreed that the production and use of certain accelerators that are carcinogenic or suspected of being carcinogenic should be discontinued.
- Why is green accelerator important for rubber industry?
- However, the present accelerators generally pose potential risks to human health and the environment，and are suffering with their poor efficiency and sole function. Therefore, developing novel green accelerator that is non-poisonous, free or low zinc oxide content added，high-effective and multifunctional, is critical for rubber industry.
