Now, the dream has become a reality. Figure 19.5 shows 3D-TEM images of three NR vulcanizates, cured by sulfur/N-cyclohexyl-2-benzothiazolyl-sulfenamide (CBS) curing system, CB-10, CB-40, and CB-80 containing 10, 40, and 80 phr high-abrasion furnace (HAF) carbon black. In the black and white images the contrast was reversed, and the white is identified as the carbon black. Association to aggregates is observed even in CB-10 (volume fraction is 0.0498). [Pg.547]

Applications Identification of polymer additives by TLC-IR is labour intensive and comprises extraction, concentration of extracts, component separation by TLC on silica, drying, removal of spots, preparation of KBr pellets and IR analysis. The method was illustrated with natural rubber formulations, where N-cyclohexyl-2-benzothiazyl sulfenamide, IPPD and 6PPD antioxidants, and a naphthenic plasticiser were readily quantified [765]. An overview of polymer/additive type compounds analysed by transfer TLC-FTIR is given in Table 7.80. [Pg.534]

Figure 12.5a shows the effect of filler loading on the volume resistivity of MWNTs and CB (CB Ensaco 250G from Timcal) filled composites based on insulating styrene-butadiene rubber. The styrene-butadiene rubber contains 25 w% of styrene units. The microstructure of the butadiene phase is the following 10% cis, 17% trans, 73% 1,2. It was compounded with sulfur (1.1 phr), cyclohexyl benzothiazole sulfenamide (1.3 phr), diphenyl guanidine (1.45 phr), stearic acid (1.1 phr), zinc oxide (1.82 phr) (phr = parts per hundred parts of rubber). The unfilled and filled samples are cured into films (around 200 pm thick) at 170°C during 10 min under a pressure of 150 bar in a standard hot press. [Pg.351]

Sulfenamides, made from 170, by reactions involving primary and secondary amines under oxidizing conditions, include A-cyclohexyl-2-benzothiazole sulfenamide (173) and N-oxydiethylene-2-bcnzolhiazolc sulfenamide (2-(morpholinothio)benzothiazole) (174). Sulfenamides release 2-mercapto accelerators and amine during vulcanization. The amine is a secondary accelerator that brings about fast vulcanization after a slow start. Applications include in tyres and conveyor belts. They are not applicable to hot-air vulcanization processes95. [Pg.768]

Thiazoles are derivatives of benzothiazole compounded with sulfenamides. The benzothiazoles include 2-MBT, dibenzothiazyl disulfide (MBTS) and the zinc salt of 2-mercaptobenzothiazole (ZMBT). The sulfenamides are principally N-tert-butyl-2-benzothiazyl sulfenamide (TBBS), N-cyclohexyl-2-benzothiazyl sul-fenamide (CBS) and morpholinylmercaptobenzo-thiazole (MOR). MBT, MBTS and CBS are the more widely used. Because of their strong capacity to sensitize, thiazoles are less frequently used in gloves than are the thiurams. Nonetheless, they are widely used in the rubber industry, as well as others (Table 7). Indeed, MBT remains the most widely used accelerator for industrial rubber (Feinman 1987). Nonetheless, sensiti-... [Pg.704]

Altenau and co-workers [26,27] used MS to identify quantitatively volatile antioxidants in 0.02-0.03 inch thick samples of synthetic styrene-butadiene rubbers and rubber-type vulcanisates. They extracted the polymer with acetone in a Soxhlet apparatus, removed excess solvent, and dissolved the residue in benzene. Substances identified and determined by this procedure include N-phenyl-P-napthylamine, 6-dodecyl-2,2,4-trimethyl-l,2-dihydroquinolines, trisnonylphenylphosphate, isobutylene-bisphenol, 2-mercaptobenzothiazole sulfenamide (accelerator), N-cyclohexyl-2-benzothiazole... [Pg.234]

Solution styrene butadiene rubber (S-SBR) (Sprintan SLR-4601, Styron Deutschland GmbH) and acrylonitrile butadiene rubber (NBR) (Perbunan 3445F, Lanxess GmbH) with a nitrile content of 34% as well as NR (SMR 10, Standard Malaysian Rubber) were used as rubbers. The silica used was Ultrasil 7000 GR (Evonik Industries) with a specific surface area CTAB of 160 m /g and BET of 170 m /g. Stearic acid, zinc oxide (ZnO), N-cyclohexyl-benzothiazole-2-sulfenamide (CBS) and sulfur were used as processing and curing additives, respectively. The experimentally determined values of surface tension and Mooney viscosity of the materials used are given in Table 6.1. [Pg.164]

Other accelerators such as CBS (N-cyclohexyl-2-benzothiazole sulfenamide) can substitute for TBBS, but there may be some differences in the scorch, cure rate, state of cure, and other properties. [Pg.277]
