Tear Resistance
Resistance to the growth of a cut in the seal when tension is applied.
Temperature Range
The working range marked by the limits of minimum and maximum operating temperatures for effective seal performance.
Tensile Strength
Pull-apart strength. A measure of the compound's strength when stretched to the breaking point.
Terpolymer
A polymer resulting from the chemical combination of three monomers.
Thermal Expansion
Linear or volumetric expansion caused by temperature increases.
Thermoplastics
Polymeric materials that soften and can be re-formed when heated, returning to original properties when cooled.
Thermoset
Elastomers 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.
Torque
A turning or twisting force, generally associated with the rotation of a shaft.
Torsional Strength
Ability 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.
Trim
Removal of excess material (flash) from a molded rubber article.
Trim Cut
Damage to the molded article by trimming too close.
