Abstract

In some cases, products of special purpose require application of sealing details on the basis of the elastomer, capable to provide working capacity at high temperatures at least short time. The choice for the specified purposes of rubbers is caused by unique highly elastic properties of the elastomer, allowing providing the hard contact of surfaces at small pressing effort. Besides, in this case process of assembly and forming of seal assembly in products of difficult configuration considerably becomes simpler. Application for these purposes of more heat-resistant metals or fluoroplastic is connected with considerable technological difficulties. The solution of the specified problem is impossible without development of compounding of rubber, ability to provide necessary technical characteristics in the expanded temperature range. Besides, features of creation of compounding and property of the specified rubber in many respects define both approaches to development and choice of optimum options of manufacturing techniques of products from it. The declared approaches will allow not only developing rubber with considerably improved complex of properties, but also in the maximum degree to keep them upon transition to manufacturing of specific products.
