LLC Scientific and Production Firm "Heat-resistant products" it was created in 1993, employees of one of laboratories of department of "Heat-resistant fibers" of NPO Himvolokno Mytishchi were its part. A primary activity of firm is development of technology of receiving heat-resistant fibers and threads on a basis polyoxadiazofishing and their modifications on what patents are taken out. At the initiative of the staff of firm and with their direct help on RUP "Svetlogorsk ON "Man-made fiber" production is created and production of heat-resistant fiber and a thread under the Arselon and Arselon-S trademark which owner in the Russian Federation is the firm is mastered. The staff of firm carry out a lot of work on increase in production of fiber and a thread Arselon on RUP "Svetlogorsk ON "Man-made fiber", to development of technology of processing of production of "Arselon", expansion of scopes. The firm developed filter fabrics (the patent is held), nonwoven cloths from which the firm makes having sewed the filter sleeves, the technology of receiving a yarn and fabric is developed for production of overalls, gloves, mittens (the patent is held), the production technology of svetostabilizirovanny Arselon-S fiber is developed, production of the light stabilizer is created, the compounding of dyeing of fiber and fabric from Arselona-S is developed, unique properties of the composite materials made with Arselon's application are shown. These developments allowed to use production Arselon in many spheres, both for the solution of environmental problems, and for protection against influence of the increased temperatures. Experience of firm on production of heat-resistant products is widely used now by other businessmen and the organizations. Since 2002 the firm is a participant of the interstate program of the Union State of Russia and Belarus "Creation and the organization of a mass production of the equipment for production of special chemical fibers for 2002-2006". One of the purposes of which is creation of production of fiber with a power of 1500 tons per year Arselon. The scientific developments which are carried out by firm on improvement of technological process of receiving fiber Arselon and his modifications do possible to receive fibers with higher operational characteristics, including on durability, thermal stability, hydrolytic firmness that will allow to receive further new types of fabrics, nonwoven and composite fabrics on their basis.
