Glossary of Rubber Industry and Synthetic Rubber Terms
Accurate Rubber provides the following glossary.
Abrasion Resistance: The resistance to surface loss of a rubber material due to frictional forces
Compression Set: The ability of rubber to return to its original thickness after prolonged compressive stresses at a given temperature and deflection.
Elongation: The term “elongation” is used to describe the ability of a rubber compound to stretch without breaking.
Flame Resistance: Rubber that will not support combustion under ordinary conditions.
Resilience: Capability of a material to return to its original size and shape after deformation. It is generally expressed in percentage of ratio of energy returned by rubber to the energy used in compressing rubber.
Tear Resistance: The resistance to growth of a nick or cut when is applied to a test specimen. (ASTM D-624.) Expressed as pounds per lineal inch.
Tensile Strength: The tensile strength of a rubber compound is in its resistance to rupture under tension. It is measured as strength at break and expressed in pounds per square inch of cross section. This property has an absolute value in some applications where the product is actually subjected to tension in service but, like the other tensile properties, it is most frequently used in evaluating compounding materials on a cooperative basis.
