A study of the thermal behavior of cured elastomeric blends of natural rubber (NR) and styrene butadiene rubber (SBR) prepared by solution blending in toluene is presented. Binary blends with different compositions of NR/SBR were produced using a conventional cure system based on sulfur and TBBS ( n ‐ t ‐butyl‐2‐benzothiazole
NOVEL SULFENAMIDE ACCELERATORS FOR IMPROVED NETWORK
1. 1.-11. (canceled) 12. A vulcanizable rubber composition comprising a diene rubber and sulphur characterized in that the said composition is stabilized by incorporating a stabilizer/accelerator material substance selected from a group of 4-substituted 2-benzothiazole sulfenamides of the general formula I, wherein R 1 and R 2 can be the same or different and
They belong to ultra fast accelerators. They are used mainly during vulcanization of latex systems (e.g. during foam-rubber production) and rubber solutions. Some of them are soluble in water. As they cause very fast vulcanization they are suggested for lower vulcanization temperatures application, the most often from 80 to 110 °C.
Pukhraj Group
It is an accelerator with delayed action sulphenamide for NR, SBR, BR, NBR and other sulphur / sulphur donor cured diene rubbers. It is very active above curing temperature of approx. 140°C and hence offers very good scorch safety during rubber compound processing operations (e.g. extrusion, calendaring, etc.) and improves the storage life of
