We specialize in the development, production and sale of chemical products for various purposes, electrical insulation materials for a wide range of electrical machines, high-voltage electrical machines, traction motors of direct and alternating current, asynchronous motors with variable frequency drive, low-voltage electrical machines, cable industry and other industries.
By casting according to smelted models (precision casting), castings weighing from several grams to tens of kilograms with a wall thickness of up to 0.5 mm are made. The essence of the casting process for the smelted models is as follows. Models of parts and a gate system are made from low-melting model compositions in special molds.
The properties of oligoesteracrylates make it possible to use them in the production of lacquers and enamels for metal and wood, adhesives and sealants, binders for composite materials, electrical insulating compounds, contact lenses, optical parts, printing plates, and are also used to modify high-molecular compounds, asbestos products, rubbers and plastisols.
Impregnating electrical insulation compounds KP-303V and KP-303VK are designed for impregnation of windings of electric machines with insulation of class B (130oC), F (155oC), H (180oC) on drip (jet) installations with current and radiation drying, on vacuum injection installations and by dipping.
Novomoskovsk Polyesters LLC is the developer and the only manufacturer of the finished binder GS-20I (STO 12455361-15-2016).
The finished binder GS-20 completely replaces the mixture of Ethyl Silicate and ethyl alcohol, while no change in the technological mode of manufacturing ceramic molds is required.
We offer the supply of raw materials from China on favorable terms!
