Mixland + predispersed rubber chemicals are a new generation of products that take the consistency, uniformity, quality and handling of predispersed chemicals to a new level of performance. Based on a unique and patented binder system, and production technology, Mixland + predispersions represents the highest quality, cost effective products to the rubber market. Filtered at levels not previously possible, Mixland + products are ideal for all applications where high dispersability, thermal stability and surface finish are pre-requisite requirements.
Mixland + MBT - 2-Mercaptobenzothiazole – MBT is a medium fast and scorchy accelerator for natural and synthetic rubbers. Vulcanisates accelerated with MBT tend to have low modulus, very good ageing properties and little tendency to discoloration. But care should be taken because it has a slight tendency to scorch.
It is suitable for NR, IR, BR, SBR, NBR, IIR and EPDM but is unsuitable for products connected with food stuffs due to its bitter taste.It can also be used as a retarder for sulphur-modified CR.
Mixland+ MBT readily disperses in rubbers. It is very active at temperatures above 130-135°C. It can be used alone but low temperature curing can be achieved by the use of TMTD, TETD or DPG as secondary accelerators.
