Russian Mining Chemical Company LLC (RMCC) is expanding its range of high grade magnesium compounds and announces the launch of high active magnesium oxide production. The product is manufactured at the recently opened third processing plant in Vyazma, Smolensk region, Russia, and is marketed under the MagPro® trade name.
MagPro® is manufactured on a new calcination line constructed in Germany. The line designed according to the latest innovative technologies ensures a consistently high quality end product.
Micronized grades of magnesium oxide are most widely used in the production of halogen-containing synthetic rubbers. In particular, MagPro® is used as an inhibitor of premature polymerization, an acid acceptor (HCl) during the production of synthetic rubber. In SMC and BMC production it acts as a thickener in premixes and prepregs.
Using MagPro® in rubber products manufacture has many advantages, as MagPro® is a natural product obtained by indirect calcination of high quality brucite from the company's mining operation site in Kuldur. This technology helps to avoid contamination of the magnesium oxide with the residues of fuel combustion and also prevents overheating of the product which would have caused its activity decrease.
MagPro® has a precisely defined particle size distribution and a specific surface area of more than 140 m2/g. Thanks to the state-of-the-art technology for selectiing raw materials by X-ray radiometric separation of ore, MagPro® has a very stable chemical composition. Moreover, due to its mineral source it does not contain any volatiles like chlorides and sulphates. All these features help MagPro® to provide the same or even better performance than the much more expensive synthetic grades of magnesium oxide.
Thus, taking into account the state-of-the-art technology and properties of the product, MagPro® has the best price-quality ratio in comparison with the alternative grades of magnesium oxide.
The line has a capacity of 7,500 tons per year. The final commissioning took place in November 2018.
