Natural gum rubber (NR) is just that, a naturally occurring organic elastomer. Natural gum rubber is most commonly used in mechanical applications where high resilience to abrasion, good tensile, and tear properties are required. Natural gum typically has better flexibility at low temperatures then most synthetics, but is not chemically inert, therefore it is inferior to most synthetic elastomers when it comes to resistance to ozone, sunlight, oxygen, solvents, and oils, Norwesco stocks AB-135 40A with a temperature range of -45C – 70C in 48″ wide rolls in thicknesses of 1/8″, 1/4″, 3/8″, 1/2″, and 1″.
