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 + TMTM - Tetramethyl thiuram monosulfide – TMTM is generally used as a secondary accelerator or as a booster for sulphenamides to achieve faster cure rates. It can be used as a booster for thiazoles and guanidines in general purpose elastomers as well. Its main application is in NBR in combination with MBT or MBTS where it acts as an activator and gives excellent balance of physical properties. In comparison with other thiurams, it has very good processing safety, high curing activity and absolutely no discoloration. Being a monosulphide, TMTM will not cure completely without sulphur. It increases the cure rate and the torque, like other thiurams, but with a much smaller reduction in scorch time.
It is also a primary accelerator for CR together with DPG or DOTG. Especially in mercaptan-modified polychloroprene rubbers, it may be used together with DOTG and sulphur to give very safe processing compounds.
It is suitable for NR, IR, BR, SBR, NBR, IIR and EPDM.
