Natural rubber aging.Natural rubber aging. This report presents information on a recently completed comprehensive natural aging and physical testing program on 19 rubber compounds, stored in controlled conditions for a period of 40 years. Rubbers studied include natural rubber, styrene sty·renen. A colorless oily liquid from which polystyrenes, plastics, and synthetic rubber are produced. Also called vinylbenzene. butadiene rubber, butyl rubber, polychloroprene, nitrile rubber, acrylate Noun 1. acrylate - a salt or ester of propenoic acid propenoate salt - a compound formed by replacing hydrogen in an acid by a metal (or a radical that acts like a metal) rubber, chlorosulfonated polyethylene, polysulfide pol·y·sul·fide n. A sulfide compound containing at least two sulfur atoms per molecule. rubber and silicone rubber. Samples were stored under temperate and tropic climatic conditions, and at various intervals properties were measured, including hardness, volume change, resilience, volume and surface resistivity resistivity Electrical resistance of a conductor of unit cross-sectional area and unit length. The resistivity of a conductor depends on its composition and its temperature. , tensile strength, elongation at break, modulus at 100% and 300% elongation, long and short term compression set, and low temperature stiffness.
