Definition |
|
T Dimension
|
The outside diameter of the thread helix on a bottle finish.
|
|
Tab Gated
|
A small removable tab of approximately the same thickness as the mould item, usually located perpendicular to the item. The tab is used as a site for edge gate location, usually on items with large flat areas.
|
|
Tack
|
Stickiness of an adhesive, measurable as the force required to separate an adherend from it by viscous or plastic flow of the adhesive.
|
|
Tack Range
|
The period of time in which an adhesive will remain in the tacky-dry condition after application to an adherend, under specified conditions of temperature and humidity.
|
|
Tackifiers
|
Additives used to enhance the adhesiveness or bonding ability of a material.
|
|
Tapered Cylinder
|
Refers to a particular shape of a container in which the circular cross section at the top is smaller in diameter than that at the bottom, or vice versa.
|
|
Tapping
|
Cutting threads in the walls of a circular hole.
|
|
TDI
|
Toluene diisocyanate
|
|
T-Die
|
A term used to denote a centerfed, slot extrusion die for film which in combination with the die adapter resembles an inverted T.
|
|
TEEE
|
Thermoplastic Elastomer,Ether-Ester
|
|
Telomer
|
A polymer composed of molecules having terminal groups incapable of reacting with additional monomers, under the conditions of the synthesis, to form larger polymer molecules of the same chemical type.
|
|
Tenacity (gpd)
|
The term generally used in yarn manufacture and textile engineering to denote the strength of a yarn or of a filament for its given size. Numerically it is the grams of breaking force per denier unit of yarn or filament size; grams per denier, gpd. The yarn is usually pulled at the rate of 12 in/min. Tenacity equals breaking strength (gms) divided by denier. (Tenacity, gpd) (Spec. Gravity) 12,800 = (Tensile Strength, p.s.i).
|
|
Tensile Bar (Specimen)
|
A compression or injection moulded specimen of specified dimensions which is used to determine the tensile properties of a material.
|
|
Tensile Modulus
|
(Also called modulus of elasticity). The ratio of nominal stress to the corresponding strain below the proportional limit of a material.
|
|
Tensile Strength
|
The pulling stress, in p.s.i, required to break a given specimen. Area used in computing strength is usually the original, rather than the necked-down area.
|
|
Tensile Strength, Break
|
The maximum stress that a material can withstand without breaking when subjected to a stretching load.
|
|
Tensile Strength, Yield
|
The maximum stress that a material can withstand without yielding when subjected to a stretching load.
|
|
TEO
|
Thermoplastic Elastomer, Olefinic
|
|
TES
|
Thermoplastic Elastomer, Styrenic
|
|
TFE
|
Polytetra fluoroethylene
