    Rubber sheet GOST 7338-90

    The sheet is produced as sheets and rolls. Vulcanized rubber sheet is designed for the manufacture of parts used to seal fixed joints preventing friction between the metal surfaces, for perception of single shock loads in machines and units used in various areas of national economy, as well as gaskets, flooring and other not sealing products. There are two types of sheets depending on the application, design and method of manufacture:

    - Type I - rubber sheet;

    - Type II - rubber-fabric sheet with one or more layers of fabric. The number of fabric layers is determined by agreement between the manufacturer and the customer;

    Two types:

    - F - shaped sheets manufactured by vulcanization in molds on vulcanizing press;

    - N - Non-shaped plate manufactured by vulcanization in boilers, as well as on continuous vulcanizers.
