limit versus the risks for skin sensitisation of MBT. In mid 2002, the Danish Environmental Protection Agency (DEPA) commissioned a study to measure the release of MBT (used as rubber vulcanising agent or accelerator) and three anti-oxidants (BHT, A2246, and A425) from natural rubber soothers and teats, and BHT, A2246 and
Environmental protection accelerator ZBEC can replace some
The production and sales volume of products have been growing rapidly.With people's attention to health and environmental protection, and the pursuit of quality of production and life, the market prospect of new environment-friendly rubber auxiliaries is promising, and the range and amount of ZBEC promoter will increase.
Effects of accelerators on the cure characteristics
accelerator and diphenylguanidine (DPG) and Zn-2-mercaptobenzothiazole (ZMBT) as secondary accelerators, were incorporated into a premixed NR compound referred to an industrially used rubber mat formulation by using the melt mixing method. The cure characteristics, rubber crosslink density and mechanical properties were the focus in the
Rubber additives industry to the bottleneck? - Knowledge
As we all know, in the processing of rubber industrial products, in addition to the main material of rubber, it is necessary to add a number of coordination additives, such as curing system of various additives, filling and reinforcing system of various additives, aging system of various additives and so on.Today we are going to talk about the bottleneck factors that limit the technical
CN102827102A - Refinement method of rubber vulcanization
The invention relates to a refinement method of a rubber vulcanization accelerator MBT (2-mercaptobenzthiazole), which comprises the following steps: adding crude MBT into a reactor filled with a 2-30 wt% NaOH solution, and keeping the temperature in the reactor at 60-90 DEG C until the MBT is dissolved into an M-Na salt solution and the end point pH value of the solution is kept at 9.5-12.5

Metabolism of 2-Mercaptobenzothiazole by Rhodococcus rhodochrous
The annual MBT production in Western Europe is estimated to be excess of 40,000 tons. Direct discharges of MBT occur in effluents from factories producing and using MBT. Indirect sources of environmental contamination are mainly leachates from landfills where MBT is deposited and from rubber products .
