TTear ResistanceResistance to the growth of a cut in the seal when tension is applied. Temperature RangeThe working range marked by the limits of minimum and maximum operating temperatures for effective seal performance. Tensile StrengthPull-apart strength. A measure of the compound's strength when stretched to the breaking point. TerpolymerA polymer resulting from the chemical combination of three monomers. Thermal ExpansionLinear or volumetric expansion caused by temperature increases. ThermoplasticsPolymeric materials that soften and can be re-formed when heated, returning to original properties when cooled. ThermosetElastomers that undergo a permanent chemical crosslinking of molecules when processed, heated and molded, and therefore cannot be reprocessed. TIR (Total Indicator Reading)A measurement of roundness with relationship to a centerline and expressed in total diametric deviation. TorqueA turning or twisting force, generally associated with the rotation of a shaft. Torsional StrengthAbility of a seal to withstand damage due to twisting. TPE"Thermoplastic Elastomer" combines the rubber-like performance of elastomers with the processing advantages of plastic. Scrap material can be recycled without significant loss in physical properties, unlike thermoset materials. TrimRemoval of excess material (flash) from a molded rubber article. Trim CutDamage to the molded article by trimming too close. |
