Description of products

The Company manufactures polypropylene registered under the Kaplen® and Rispol® trademarks.
Unpainted stabilized polypropylene comes in the form of granules of 2-5 mm. The compositions of the stabilization formulations include antacids, anti-static, high temperature stabilizers, light stabilization, antioxidant supplements, due to which polypropylene acquires high resistance to oxidative aging, increased resistance to detergents and fading, improved antistatic and technological properties.

The Company’s production capacity covers 25 grades of polypropylene with melt index of 0.2 to 40 g / 10 min, 3 grades of them are lightfast and possess colour stability against corrosive industrial gases. 22 grades are granted the Rospotrebnadzor permission to be used for manufacturing products contacting with food products.

Polypropylene is designed for the production of injection molding, extrusion, blow molding products, such as pipes, fittings, sheets, tapes, films, packaging and nonwoven materials, fibers, monofilament, film threads and other products for technical, household and medical purposes. Products manufactured by NPP Neftekhimia LLC differ consistently by high quality level. Actual quality indexes are much higher then those standardized by the Kaplen specifications.
