> Control Experimental Ingredients Centrifuged dust stop -- 10 lubricating oil Aromatic oil (RPO 701) 10.0 -- Other ingredients used in the above formulation kept constant were: NR (EBC # 3X)--90.0; SBR 1502--10.0; N330 black--45.0; PCTP
(Peptizol 7) - 0.10; zinc oxide--4.0; stearic acid--2.0; 6PPD (Pilflex 13) --0.5; TMQ (Pilnox TDQ)--2.0; P.
The study shows that the granulated, dust-free peptizer 11/WG, which is based on specifically activated DBD, is an appropriate substitute for the discontinued peptizer 7/WG, which was based on activated PCTP
. In NR skim compounds for rubber-to-steel cord adhesion, the behavior of 11/WG is similar to that of 7/WG in terms of the basic mechanical vulcanizate properties before and after aging, the heat build-up, the viscoelastic and the adhesion properties.
