dpg is often used as a secondary accelerator in the vulcanization process, endowing the rubber with high modulus and high tensile strength. because dpg is difficult to dissolve and disperse in water, rubber industry generally needs ball milling to maintain the dispersion effect of dpg; otherwise, dpg would make nr latex exhibit gelation
mbt(m) rubber accelerator: enhancing performance in rubber,mbt(m), also known as 2-mercaptobenzothiazole, is a widely used rubber accelerator that plays a crucial role in the production of rubber products. this article aims to provide an in-depth understanding of mbt(m), its characteristics, its applications in rubber production, its compatibility with other products, and the key factors to consider when commercially procuring mbt(m) for business
on the various roles of 1,3-diphenyl guanidine in silica
the aim of this study was to evaluate the various roles of 1,3-diphenyl guanidine (dpg) in silica-reinforced rubber compounds. two roles of dpg are well known to be: adsorption onto silica surface to reduce the acidic sites and second to boost the silanization reaction as secondary accelerator. however, these two roles are in a way conflicting.

choice of accelerators of the vulcanization group for rubbers
abstract— the effect of vulcanization accelerators on the structure and properties of rubbers based on hydrin t6000 epichlorohydrin rubber was studied. as accelerators, we used mercaptobenzthiazole (mbt) in the amount of 1.5 pts. wt., tetramethylthiuram disulfide (tmtd) in the amount of 0.5 1.5 pts. wt., and n,n'‑diphenylguanidine (dpg) in the amount of 0.5 1.5 pts. wt., which
vulcanization accelerators for tyre manufactures,vulcanization of rubbers by sulfur alone is an extremely slow and inefficient process. the chemical reaction between sulfur and the rubber hydrocarbon occurs mainly ac (doublet the c = bonds ) and each crosslink requires 40 to 55 sulphur atoms (in the absence of accelerator). the process takes around 6 hours at 140°c
unveiling dpg rubber accelerator: features, applications, and supplier,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.
- What is accelerator in rubber vulcanization?
- An accelerator is defined as the chemical added into a rubber compound to increase the speed of vulcanization and to permit vulcanization to proceed at lower temperature and with greater efficiency. Accelerator also Decreases the Quantity of Sulphur necessary for vulcanization and thus improving 'aged' properties of the rubber vulcanizates.
- Why is DPG used in vulcanization?
- The reason is that the final concentration of DPG in the vulcanization step was eventually the same. If DPG blocks the access of silane molecules by absorption onto the silica surface, the vulcanization efficiency and crosslink density would be lowered as the amount of adsorbed DPG increases.
- Can DPG-hp--CD be used as a vulcanization accelerator?
- The purpose of this paper is to solve the insoluble and toxic problems of DPG when it is used as a vulcanization accelerator. Hence, we innovatively propose a design strategy for the inclusion complex of DPG-HP- β -CD by ball milling.
- Which accelerator is used for vulcanization?
- The basic accelerators such as Guanidines, Thiurams, and Dithiocarbamates etc are used as Secondary accelerators to activate the primary accelerators. The use of secondary accelerators increases the speed of vulcanization substantially but at the expense of scorch safety.
