The Effect of Nitrogen-Phosphorus Containing Compounds on the Flammability of Fibrous Materials Based on Ultrahigh Molecular Weight Polyethylene with Polyurethane Binder

Abstract

Studies have been conducted on the fire resistance and fire hazard properties of materials made of ultrahigh molecular weight polyethylene fibers with polyurethane rubber-based binder, and the effect of various flame retardants on these properties. Introduction of compounds containing variable combinations of nitrogen and phosphorus fragments leads to decrease in the flammability of samples due to simultaneous action of antipyretic elements in the condensed and gaseous phases of the burning material. The addition of aluminum hydroxide leads to a synergistic effect of the action of flame retardants, as well as to a significant increase in the fire safety of the material.
