Sheet sealing material BR-1

BR-1 material is mainly used in the form of gaskets of various sizes and configurations for sealing joints of vessels, machinery, pipelines operating in environments of water, steam, kerosene, gasoline, diesel fuels, mineral oils and their mixtures at temperatures from -60 to +200 degrees C and at a pressure of no more than 1 MPa.

Suitable for work in the Far North, temperate and tropical climates. BR-1 material is not corrosive when working with clad aluminum alloy D-16, brass L63, steel 25, 30HGSA, oxidized magnesium alloy ML5.

The material is supplied in the form of sheets with a size of 500x500 mm and a thickness of 0.5 to 3 mm. The guaranteed shelf life is 2 years after production.
