Consumers of these products have significant benefits. Use of UFC in urea-formaldehyde resins production will allow to:
- have the process with the stage of product concentration free; reduce the production costs;
- find the solution for recovery of formaldehyde content waste water, methanol and FH gaseous emissions;
- reduce the transportation costs up to 40% since to produce the same quantity of UFR the amount of UFC will be required by 1,6-2,2 times less than formalin;
- reduce the demand of urea by 25%;
- provide the synthesis of low toxic resins with high resistance and special structure of polymers;
- provide high quality of urea-formaldehyde resins produced (methanol content up to 0,2%), manufacture E-1 class particle boards;
- reduce methanol emission many times when pressed.

- 10. POLYAMIDE 6 GRANULATED OST 6-06-Ñ9-93
Application:
JSC Metafrax produce polyamide 6 granulated, Grades PA 6-210/310 and PA 6-210/311. Polyamide granules production unit was put into operation in March 2002.
Polyamide 6, Grades PA 6-210/310 and PA 6-210/311, is used in chemical industry, mechanical engineering, shipbuilding and aircraft, instrument engineering to produce the parts of construction and antifriction purpose: bushes, rollers, rings, bearing inserts, valves and likewise items.
Polyamide 6 products perfectly absorb impact loads; they are long lasting, they have low friction coefficient and can work without lubrication in the friction points. In addition polyamide is an excellent dielectric, which is just as strong as polystyrene, polyvinyl chloride etc and as for mechanical and heat resistance it even excels these materials. Polyamide articles substitute for metals.
Production: Produced in the process of E-caprolactam hydrolytic polymerization in the presence of catalysts and stabilizers.

Our company mastered a technique to produce finished moulded (granulated) polyamide 6 products, including articles used for superstructures operation, by means of injection casting on automatic injection machines.
We are ready to provide Ministry of railroads with the following finished products that can be bought on a regular basis:
Insulation items kit for foundation angle pieces of switch units Ð-50 and Ð-65 in compliance with TU 32 ÖØ 3667-97 and TU 32 ÖØ 2047-97. Test were performed on the ÂÍÈÈÆÒ Ministry of railroads certified test benches according to the requirements of TU 32 ÖØ 3667-97 (Gaskets, insulating foundation angle pieces for electric drives away from a rail) and TU 32 ÖØ 2047-97 (Insulation items for switch units).
Insulating strips under TU ÖÏ 369 TU-4 made from polyamide 6 granulated Grade PA 6 210/310 OST 6-06-Ñ9-93. The tests were performed on the ÂÍÈÈÆÒ Ministry of railroads switching test bench (certificate ¹ ÂÝÈ-5000-003-99).
- 11. DIELECTRIC SAFETY RINGS "SPACERS" TU 2291-034-00203803-2005
Spacer is a dielectric safety ring installed to protect the underground pipelines if they are routed in chucks under highways and railways, and to make the protective screen in the system Pipe - Chuck - Ground.
Special reliability, long life and safety requirements are made to the rings. The structure of rings "Spacer" does not have any metal parts going into contact with pipeline that excludes any possibility for center of corrosion to form and damage of the pipeline. The ring consists of segments easily mounted directly on the pipeline surface by means of bolt joint. The number of segments in a ring depends on a pipe diameter and can be unified for the pipelines with diameters 57 -1420 mm.
Monolithic segment of a ring made of synthetic construction material combines strength and dielectric properties: PA-6 strength (while compressing at 57...81 MPa); dielectric constant of material 3,6 (at 10 6 Hz). The material has a low slip ratio on metal surfaces (slip ratio = 0,3 without any lubrication) that is important while inserting into a cathead. Segments are produced by precision pressure casting and this fact along with the application of our own raw materials allows us to reduce significantly the segment-making costs. Thanks to low weight and mobile design these rings are evacuable. One three-ton container is able to volume rings for fifteen standard (L = 60...70 m) crossings with a passage diameter 1420 mm. Our company is conveniently located from geographical point of view that allows our clients to use motor transport including passing motor transport of our transport subdivision.
Used in pipeline crossings being under construction and to be revamped, in climatic zones at the erection and operation temperature for steel pipelines from 70 to - 50 Ñ, and for the polymer pipelines at the temperature allowable for the polymer.
We have Product Authorization given by Federal Service of the ecological, technological and atomic control (Rostechnadzor) and Technical certificate for the product applicability for the construction works on the territory of RF.
- 12. DIELECTRIC LINING BARS (battens)TU 2291-035-00203803-2007
Lining bars (battens) are used for protection against mechanical damages of insulation coats of steel and polymer pipelines without insulation coating when pulling them through the water barriers and also for picking up the safety dielectric rings employed for pulling the pipeline through casing (siphon), for construction of the underground crossings through a highway, railroad or water barrier including the method of down-the-hole drilling type "annular tube". Lining bars (battens) are manufactured out of polyamide 6 Grade 210/310 under OST 6-06-Ñ9-93.
Lining bars (battens) are used to build up crossings of gas mains and gas-distribution systems of oil pipelines, oil-products pipelines, water pipelines and other pipelines made from steel pipes with the outside diameter from 57 to 1420 mm for all climatic zones of the country including the regions where the design outdoor air temperature is up to minus60ºÑ, at the erection and operation temperature from 70 to minus 50ºÑ and for pipelines consisting of polymer pipes with outside diameter from 63 mm up to 500 mm - at temperature allowable for the polymer.
