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.
a comparison of tetraethylthiuram and tetramethylthiuram,a sustainable and atom-economic synthesis of the widely applied rubber accelerator tetramethylthiuram monosulfide (tmtm) from tetramethylthiuram disulfide (tmtd) is reported.
unveiling dpg rubber accelerator: features, applications
dpg (diphenyl guanidine) is a versatile rubber accelerator with notable characteristics, including medium-fast acceleration, moderate reactivity, good scorch safety, and excellent vulcanization properties.

- What is DPG (diphenyl guanidine)?
- DPG (Diphenyl Guanidine) is a widely used rubber accelerator that plays a vital role in the production of rubber products. This article aims to provide an overview of DPG, its characteristics, its applications in rubber product manufacturing, potential product combinations, and important considerations for commercial procurement. 1. What is DPG?
- Is diphenyl guanidine a catalyst booster?
- The presence of an amine-based secondary accelerator such as diphenyl guanidine (DPG) in the silica-reinforced rubber compounds plays an additional role as a catalyst booster for the silanization reaction [6, 7].
- What are the characteristics of DPG rubber?
- 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.
- Does diphenyl guanidine and Hex have the same flocculation rate constants?
- Diphenyl guanidine and HEX that gave similar rate constants of the primary silanization reaction in the model systems exhibited the same flocculation rate constants as a result of the enhanced silanization by the amines. Among the linear aliphatic amines, the rubber compound with HEX showed a lower flocculation rate constant than with DEC and OCT.
