  • 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.
  • What is the function of DPG in silica/silane reinforced rubber?
  • The focus of this study was to investigate the various functions of DPG in silica/silane reinforced rubber, which can harmonize the conflicting point between the two well-known roles: adsorption onto the silica surface in order to reduce the acidity and accelerating the silanization reaction.
  • What is 1 3 diphenylguanidine (DPG)?
  • 1. Introduction 1,3-DiPhenylGuanidine (DPG) has been known for long as a common so-called secondary accelerator for sulfur-vulcanization/crosslinking of carbon-black reinforced rubber compounds.
  • Are tespt and DPG used in silica-reinforced rubber compounds?
  • DPG and TESPT are partly consumed during mixing and alter the network structure. The aim of this study was to evaluate the various roles of 1,3-DiPhenyl Guanidine (DPG) in silica-reinforced rubber compounds.
  • Is DPG a multi-purpose compounding ingredient in silica-reinforced rubber compounds?
  • DPG therefore has turned into a multi-purpose compounding ingredient in silica-reinforced rubber compounds. Many studies were done, which support all these functions of DPG, but to unravel all these roles respectively their mutual interactions remains a point of further research.
  • What is the relationship between DPG concentration and bound rubber content?
  • 3.1.2. Bound rubber content as a function of DPG concentration in the MB Total and chemically bound rubber contents are plotted as functions of DPG concentration in the MB: Fig. 8. The amount of chemically bound rubber as well as total bound rubber increase along with the DPG concentration in the MB.
