The chemical plant Nortex-Lipetsk is located in the special economic zone of Lipetsk (about 450 km from Moscow along the M4 highway). The plant was launched in 2013 and today is a full-fledged industrial enterprise with a modern production line and its own laboratory.
Nortex-Lipetsk produces high-tech polymer-bound additives for tires and rubber products under the trademark Nortgran. The plant's capacity is 1,500 tons Nortgran per year.
These additives have high chemical efficiency, stability and rapid dispersion into compounds. The use of Nortgran in the production of final products reduces the cost of recycling and minimizes the amount of defects. In addition, their advantage is the produced form in the form of granules, which ensures easy weighing and dosing, which allows for automation of the technological process. Thanks to the polymer shell of Nortgran, the product does not form chemical dust and is non-toxic, providing an optimal ecological and safe environment in production.

Vulcanization accelerator CBS can lead to long scorching time of rubber compounds, high processing safety and fast vulcanization rate. It can be used alone in low-sulfur vulcanization, and also can be used together with dithiocarbamates or thiurams. Its vulcanizate has excellent properties of anti-ageing and compression set resistance. It can obviously shorten scorching time of rubber compounds together with dithiocarbamates and thiurams. Thioureas have obvious effect on secondary acceleration to CBS, especially in low-sulfur rubber compounds. It can delay scorching and improve processing safety in thiols and thiurams rubber compounds.

HEXA is a weak alkaline accelerator for slow vulcanization. Vulcanization reaction started as soon as HEXA was added in, with a slow rate and a high degree of cross-linking of the vulcanizate. Thiols, sulfenamides, thiurams and dithiocarbamates are activators and secondary accelerators to HEXA contained rubber compounds. As a formaldehyde donor, it is especially suitable to adhesion between rubber and metal or steel cord with resorcinol. It can not lead to blooming appearance normally.

TMTD can extremely accelerate vulcanization rate of natural and synthetic rubber and has good scorching safety. It almost does not affect degree of cross-linking but delay vulcanization: only lower scorching rate and extend total vulcanization time if thiols or sulfenamides is added in. Alkaline accelerators such as aldehyde-amines and guanidines can activate TMTD. It is a primary accelerator with sulfur, a secondary accelerator with thiazoles and a vulcanizator in sulfurless vulcanization. Sulfurless or low-sulfur vulcanization can provide excellent heat-proof ageing properties for vulcanizates.
