Test and Evaluation of Liquid Polymers for Use in Army Weapon Components

Abstract

High durometer (65 to 85 Shore D) compounds based on liquid polyether urethane polymers were developed. Properties of the cured compounds investigated were pot life; stress-strain; environmental stability; resistance to various fluids and semifluids; shear, torsional, bending, and compressive strengths; and impact resistance at +75 F AND -67 F. The addition of 0.5 pphr of fine thermal carbon black to the polymers gave good resistance to 500 hours of UV exposure in a Weather-Ometer. The addition of 0.75 pphr of Wing Stay T to the black pigmented compounds further improved the UV RESISTANCE, BUT WITH A REDUCTION IN ORIGINAL STRESS-STRAIN PROPERTIES. Fluid resistance was excellent for these materials, with the exception of their resistance to gasoline and insect repellent. Rifle butt stocks and artillery handwhells fabricated from these polymers are superior to currently used stocks and handwheels fabricated from filled phenolic plastics.
