General Rubber & Plastic Terms
A cell not totally enclosed by its walls and hence interconnecting with other cells.
The surface cracks, checks or crazing caused by exposure to an atmosphere containing ozone
Heat or radiation treatment to which a cured or partially cured rubber is subjected to enhance one or more properties.
A measure of the resilience, usually as the percentage of vertical return of a body that has fallen and bounced.
A material that is capable of recovering from large deformations quickly and forcibly, and can be, or already is, modified to a state in which it is essentially insoluble (but can swell) in boiling solvent, such as benzene, methyl ethyl, ketone and ethanol-tulene isotope.
Strain remaining after complete release of the load producing the deformation.
The time an unvulcanized rubber stock can be stored without losing any of its processing or curing properties.
An arbitrary numbering scale that indicates the resistance to indentor point of the durometer. High values indicate harder materials.
A relatively dense layer at the surface of a cellular material.
Cellular rubber consisting predominantly of open cells made from a solid rubber compound.
A material upon the surface of which an adhesive is applied for any purpose such as bonding or coating.
the maximum load required to tear apart a specified specimen, the load acting substantially parallel to the major axis of the test specimen.
the maximum tensile stress applied during stretching a specimen to rupture.
an irreversible process during which a rubber compound through a change in its chemical structure (for example: cross-linking) becomes less plastic and more resistant to swelling by organic liquids and elastic properties are conferred, improved, or extended over a greater range of temperature.
the surface deterioration of a rubber article during outdoor exposure, such as checking, cracking, crazing or chalking.
