Elasticity - The property of an article which tends to return to its original shape after deformation.
Elasticity - A property of any material which makes it tend to recover its original dimensions after removal or the force which deforms it.
Elastic Modulus - The value of the load (in pounds per square inch of original cross-section) required to give an intermediate elongation, is usually called the modulus at that elongation. The expression used is "modulus at 300 percent elongation." Tensile-stress observations of this sort arc exceedingly useful in characterizing a particular compound, since by indicating the position and shape of the stress-curve. They show the relative toughness of the vulcanizate.
Elongation - Extension produced by a tensile stress.
Elongation - In the physical testing of rubber, the increase in length of a test-piece when stretched, usually expressed as a percentage of the original length; for example a 1" piece stretched (0 6" has an elongation of 500%. Elongation at break -- the elongation of a test-piece at thc moment of rupture, usually expressed as percentage of the original length.
Embrittlement - A rubber compound becoming brittle during low or high temperature exposure or in the process or aging.
Encapsulated O-rings - A rubber o-ring with a thin jacket of PTFE or Teflon surrounding the softer core material, which allows it to be used in chemical applications.
Excluders - Also called wipers or scrapers - used in a hydraulic or pneumatic cylinder to exclude and scrape the rod clean.
Expanded Rubber - Cellular rubber having closed cells made from a solid rubber compound.
Extrusion - 1) Distortion, under pressure, of portion of seal into clearance between mating metal parts. 2) Material, under pressure, which is forced through the opening of a die in order to obtain a desired cross sectional shape.
