A Thermal Protective Compound Elastic at Negative Temperatures

A compound based on polyether urethane rubber with end epoxy urethane groups and epoxy oligomers for the protection of products made of highly filled polymer compositions subject to the effect of positive and negative temperatures was developed. Its curing regularities and mechanical properties were studied. It was shown that the compound retains elasticity at the temperatures of up to –40°C and surpasses the currently used compound in terms of mechanical characteristics.
