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.
A polymer resulting from the chemical combination of three monomers.
Thermal Expansion
Linear or volumetric expansion caused by temperature increases.
Polymeric materials that soften and can be re-formed when heated, returning to original properties when cooled.
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.
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.
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.
Removal of excess material (flash) from a molded rubber article.
Trim Cut
Damage to the molded article by trimming too close.
