PU sheet, rod

 Polyurethane SKU-7L, SKU-PFL is elastomer in which the set of unique properties — firmness to deterioration is inherent, high durability, besides it it possesses firmness to shock loadings.To dignity of polyurethane  is possible to carry ability to advantages to keep   hyperelastic properties in a wide range of temperatures (from -50°C to +120°С).

  Thanks to the raised wear resistance and the lowered factor of a friction, polyurethane elastomers  were widely adopted at manufacturing of linings and consolidations of various appointment — of the static, reciprocating action, rotating, working in pneumatic, hydraulic systems or as simple  scraper consolidations for flat surfaces and shaft. Polyurethane  has found the application at manufacturing of punches and matrixes for punching of metals, these are every possible dampers  , buffers , and also a covering of shaft of different function. Besides  polyurethane elastomers are used at lining cyclones , hydrocyclones, at manufacturing of the products working in the conditions of raised deterioration.

  Elastomers based on polyurethane is used as a cover for pulling and guide rollers in the metallurgical and chemical industries, as well as shafts and drums for cutting fiberglass, glass, paper and cardboard.  In addition to the foregoing are made of polyurethane rollers for conveyor lines, solid tires for internal transport, including for work in warehouses, refrigerators. He has also found application in the mining and food industries in the manufacture of screens, internal coating screens, cyclones and separators.
