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.

mbts accelerator rubber supplier,mbts accelerator benzothiazole disulfide cas 120-78-5 mbts accelerator for rubber is a general purpose accelerator for sulfur cures. it is very active above 142°c (287°f). unlike thiuram disulfides, mbts does not split off active sulfur during vulcanization.
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.
recent advancements in silica filled natural rubber composite,the partial or total replacement of carbon black by silica fillers is initiated through various techniques for environment-friendly, smart, and fuel-efficient nr composites for high-end dynamic applications like tyre tread. the smart properties such as low rolling resistance, better wet skid resistance, and abrasion resistance as well as noise reduction, create tyre tread compounds with
effects of accelerators on the cure characteristics and supplier,diphenylguanidine (dpg) is most frequently used as a secondary accelerator to synergise with thiazole accelerators. as secondary accelerator, dpg in combination with mbts contributes to a powerful cure activation effect that imparts high modulus, tensile strength, dynamic and aging properties of rubbers [5]. in mbts acceleration systems,
- What is accelerator DPG?
- Accelerator DPG is useful as an accelerator/activator for natural rubber, SBR and NBR. It activates accelerators such as MBT, MBTS and sulfenamides. It is a strong secondary for CBTS, BBTS, OBTS, MBT and MBTS. DPG requires the use of zinc oxide and fatty acids. DPG provides satisfactory processing safety and storage stability to rubber compounds.
- What is the role of DPG in a carbon black-filled rubber compound?
- The original task of DPG in a carbon black-filled rubber compound is the support of the crosslink reaction as a secondary accelerator. Its role in a silica-filled compound is much more manifold. An addition of 1,3-diphenylguanidine (DPG) in the early mixing stage enhances the silanization reaction as well as the filler-polymer coupling.
- What is the role of DPG in elastomers?
- TYPICAL ROLE OF DPG DPG (Fig. 1) is an aminic accelerator without sulfur. It is useful as an accelerator/activator for typical elastomers like NR and SBR. It activates accelerators such as 2-Mercaptobenzothiazole (MBT), 2, 2 -Dithiobis(Benzothiazole) (MBTS) and sulfenamides. For this, it requires the use of zinc oxide and fatty acids. [1,2] III.
- What does DPG do?
- Industrial rubber goods: DPG contributes to the production of conveyor belts, seals, gaskets, hoses, and other rubber components, providing enhanced mechanical properties and improved aging resistance.
