Nitrosamine-safe thiuram disulfide and benzothiazole
In this study, the synergistic activities of the novel bis -(N-phenyl piperazino) thiuram disulfide (PPTD) and bis -(N-ethyl piperazino) thiuram disulfide (EPTD) with N-Cyclohexyl-2-benzothiazole sulfenamide (CBS) in the vulcanization of natural rubber was investigated. A comparison was made between the safe TDs/CBS systems and unsafe
A tire tread rubber composition includes: diene rubber containing three kinds of rubber (E-SBR, modified S-SBR, and natural rubber (NR)) in a total amount of 80% by weight or more; and a filler in an amount of 100 to 140 parts by weight based on 100 parts by weight of the diene rubber, the filler containing 70% by weight or more of silica, wherein the diene rubber contains 10 to 25%

Application : NS is a Vulcanization accelerator with delayed action, short cure time, has high anti-scorching quality, processing safety. Widely used in all sorts of rubber products and tires, especially the meridian tires. The product is excellent delayed accelerator with more delayed action and great curing rate and so on.
Jan 13, 2022· Fig. 1 shows the cure behaviour and Table 2 shows the cure parameters of SBR nanocomposites. According to Mathew et al., the cure parameters of the nanocomposites are influenced by the concentration and surface nature of silica. From Fig. 1, the optimum cure time and scorch time of SBR 5NS composite showed higher value owing to the absorption of
CN105503772A Preparation method for N-tert-butyl
The invention belongs to the technical field of fine chemical engineering and particularly relates to a method of preparing N-tert-butyl benzothiazole sulfonamide (TBBS) without an oxidant. In the invention, benzothiazole disulfide (vulcanization accelerator DM) and tert-butyl amine as raw materials are used for synthesizing the TBBS with an inorganic or an organic alkaline catalyst,
Mar 10, 2015· The effect of various vulcanization accelerators (MBT, TBBS, TMTD, DPG, and CBS) and two ratios of vulcanization accelerator/sulfur (2:1 as conventional (CV) and 1:2 as effective (EV) systems) on curing characteristics, mechanical properties and thermal properties of reclaimed rubber were determined.
