MANUFACTURE OF PRODUCTS FROM ЛИТЬЕВЫХ ПОЛИУРЕТАНОВ  
Feature полиуретанов - exclusively high физико - mechanical properties, on some parametres surpassing not only all types of rubbers, rubbers, but also metals. Полиуретан gives to products such useful properties which are unattainable for usual rubbers. First, this raised value of hardness (to 95 units on Шору), that allows to use полиуретан for the products working with especially strong mechanical нагружением, for example, for shaft cold proskating rinks or became flexible. Secondly, unsurpassed wear resistance and abrasive firmness. Литьевые полиуретаны surpass rubbers, plastics and metals in the abrasive firmness several times. Thirdly, at the raised hardness полиуретан keeps high elasticity, a deformation limit at rupture usually not less than 350 %. It provides very high value of durability - to 50 МПа. 
  In the conditions of constant dynamic loading the top limit of a heat of operation полиуретанов is 120С. Low temperatures do not render special influence on properties полиуретановых эластомеров to-70S.

  PROPERTIES ПОЛИУРЕТАНА:

- Полиуретаны possess high dielectric properties, have excellent firmness to oils and solvents, are not inclined to ozone ageing, have high firmness to microorganisms and a mould.
 - Литьевая the technology of formation of details allows to receive products practically any form and the sizes of rubber products inaccessible to formation.
 - High cost резинотехнических products allows полиуретанам to compete to rubber and in the price plan.
  Thanking these qualities application полиуретана economic industries in a wide spectrum including by manufacture of basic elements, sealing rings, coverings of shaft, wheels and rollers, сайлентблоков, cuffs for clearing of an internal surface of pipes of oil and gas pipelines, etc.
