  • What is DCBS used for?
  • Application: DCBS is a delayed accelerator of good dispersion quality in rubber, the scorching duration is long, which could improve the safety of operation. Suitable for the rubber that need large amount of high active reinforcer. Due to the bitterness, it's unsuitable for the product contacting with food.
  • 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.
