THE TASK IS TO PRESERVE THE INSULATION CHARACTERISTICS
UNDER THE INFLUENCE OF VARIOUS FACTORS

FOR SHIPBUILDING, MACHINE-BUILDING
AND ENERGY ENGINEERING:

  1. ATMOSPHERIC FACTORS / atmospheric precipitation,
    sea water, sunlight, etc.
  2. HIGH TEMPERATURE / 250°C and above

FOR NUCLEAR POWER ENGINEERING:

  1. ATMOSPHERIC FACTORS
  2. HIGH TEMPERATURE
  3. RADIATION /(X-ray and gamma radiation, neutron, proton, electron, etc.)

During the radiation tests of the experimental samples of the oligocyanurate binder conducted at the Budker Institute of Nuclear Physics in the context of scientific cooperation showed preservation of more than 50% of the initial strength of the samples after an electron irradiation dose of more than 300 MGy, while samples based on foreign epoxy compound (used in the isolation of magnetic coils of various accelerators) showed a 50% decrease of strength after the irradiation dose of 80 MGy. Fiberglass based on an oligocyanurate binder retained about 70% of strength after an irradiation dose of 500 MGy. Properties of carbon plastics based on oligocyanurate binder did not change after 500 MGy, means its radiation resistance is much higher. Preliminary experiments show the promise of using oligocyanurate carbon plastics at rotor rotation up to 1 million rpm.
