RESEARCH OF RESISTANCE OF RUBBERS TO THE EXPOSURE OF MOLD FUNGI

The article presents the tests results for the resistance of rubbers of three brands to mold fungi in natural atmospheric conditions and in laboratory conditions when they are artificially infected with spores. These results show that the intensity of development of fungi on the surface of rubbers is from 0 to 2 points with a norm of not more than 3 points. It has been determined that the strength properties of rubbers after exposure to mold fungi in laboratory and natural conditions are at the level of the initial ones. The paper provides the conclusion about the bactericidal properties of the components of rubber mixtures in relation to mold fungi.
