Adhesive Tape performance is expressed as numerical values, which represents the results of tests conducted under standard condition to reveal the properties of individual tapes. These indications are an useful reference to select the type of tape, which can be used in different applications.


Adhesion (Peel strength)

Adhesion is the force needed to peel off a strip of tape adhered for 10 minutes to a stainless steel plate in a 180 degree direction. This gives an indication of the difficulty in peeling off a tape. It is a typical characteristic used in determining tape performance. The values shown in this catalogue are converted to the force in gms for 1cm(10mm) width of tape.

Tensile strength

Tensile strength is the measurement of the degree of strength at which a tape pulled apart breaks. The maximum force at breakage is then converted for 1 cm(10mm) width value. Higher values denote a stronger base material.

Elongation

The elongation measurement reveals the tape's ability to confirm to a curved or uneven surface. It is measured by pulling the tape in a lengthwise direction. The value for this measurement is expressed as a percentage of the elongated length (just before breakage) to the original length.

 

Thickness

Thickness of the tape is the perpendicular distance between opposite sides of the tape including the backing and the adhesive coating. It is measured using a dial type thickness gauge where a predetermined pressure is applied on the tape before measuring. The thickness excludes the thickness of release papers.

Dielectic Breakdown(BDV)

It is a test conducted to determine Electric strength of an insulating tape by measuring the voltage at which break down occurs viz. Break Down Voltage (BDV) using Standard Test Equipment. The voltage applied between electrodes shall be raised from zero at a uniform rate unit the insulation break down. This voltage (BDV) is an indication of the Dielectric strength
