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. it finds widespread application in various rubber products, including tires, industrial rubber goods, and footwear.
rubber accelerator mbts with high quality,compounds cased on mbts have slightly better aging and reversion resistance than corresponding ones based on sulfenamides. it can be boosted by use of secondary accelerators to achieve a faster cure and higher modulus.
accelerator dpg for tyre and rubber product
product description: 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.

- What is n n diphenylguanidine (DPG)?
- N,N’-Diphenylguanidine (DPG) is a vulcanization accelerator for natural and synthetic rubbers. Furthermore, N,N’-Diphenylguanidine (DPG) a secondary accelerator, activating Thiazoles (MBT, MBTS), Thiurams (TMTM, TMTD) or Sulfenamide (CBTS) in NR (0.1-0.5phr), SBR (0.15 – 0.75phr) and NBR (0.1-0,5phr) applications.
- What is the role of 1,3-diphenyl guanidine in silica-reinforced rubber compounds?
- 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.
- Why is DPG used in silica-reinforced rubber compounds?
- Further, while reacting with the silanol groups DPG reduces the polarity of silica by being adsorbed onto the silica surface [, , ]; and finally, DPG is also capable of accelerating the silanization reaction [2,4,7,8]. DPG therefore has turned into a multi-purpose compounding ingredient in silica-reinforced rubber compounds.
- What are bound rubber contents based on DPG concentration?
- Bound rubber contents as function of DPG concentration in the MB; (): total bound rubber; (): chemically bound rubber; (): physically bound rubber. 3.1.3. Silica filler flocculation rate
