Product Description

LINQTAPE™ PIT3S-T-RL tapes are high performance, temperature resistant polyimide tapes that use a polyimide film as a backing film. This flame retardant backing film is the generic version of DuPont's Kapton HN film and has a thickness of 3mil (76.2µm). Laminatedon it is a 1mil (25.4µm) thick pressure sensitive silicone adhesive making the total thickness of the polyimide film plus adhesive only 4mil (101.6µm) thick. PIT3S-T-RL remains both electrically and mechanically stable across temperatures ranging from -269°C to 400°C (-452°F to 752°F).

Product Applications

Polyimide tape is widely used in applications requiring high electrical insulation and an excellent balance of thermal, mechanical, chemical and electrical properties. As a base material, polyimide is extremely versatile as it can be die-cut, punched and thermoformed with or without adhesive.

It is extremely well suited, and extensively used for wrapping cable and magnet wire. A further list of applications includes, but is not limited to aircraft and spacecraft wiring, insulation tubing, slot insulation, fiber optics cable, heater circuits, automotive diaphragms and manifolds, high temperature splicing and other applications that can make use of the ultra-thin, high temperature, electrically insulating properties of the PIT3S-T-RL polyimide HN tapes.

General Properties
Adhesive Layer
Adhesive Layer
A layer that is applied to one surface or both to bind items together and resist their separation
Silicone
Adhesive Thickness
Adhesive Thickness
Adhesive thickness indicates the thickness of an adhesive layer.

It refers to the adhesive thickness of a single side so for double sided tapes it always needs to be multiplied.
25.4 µm
Film Thickness
Film Thickness
Film thickness is the thickness of a backing film without taking into account any coatings or adhesive layers. It is measured in micron and the conversion factor to mil is 0.039.
76.2 µm
Single or Double-Sided Adhesive
Single or Double-Sided Adhesive
Describes whether a tape is single- or double-sided. If it is single-sided, it has adhesive only on one side of the backing film. If it is double-sided, then it has adhesive on both sides of the backing film.

Total Thickness
Total Thickness
Total thickness is taking into account all the films, coatings, adhesives, release liners and special layers and is the maximum thickness of a film or tape.
101.6 μm
Mechanical Properties
Adhesion Strength
Adhesion Strength
Adhesion is the bond strength measurement of a coating to a substrate. When an adhesive is bonded to an item or surface, numerous physical, mechanical and chemical forces come into play, which may have an effect on each other.

Electrical Properties
Breakdown Voltage
Breakdown Voltage
Breakdown voltage is the minimum voltage necessary to force an insulator to conduct some amount of electricity.
It is the point at which a material ceases to be an insulator and becomes a resistor that  conducts electricity at some proportion of the total current. 

After dielectric breakdown, the material may or may not behave as an insulator any more because of the molecular structure alteration. The current flow tend to create a localised puncture that totally alters the dielectric properties of the material.

This electrical property is thickness dependent and is the maximum amount of voltage that a dielectric material can withstand before breaking down. The breakdown voltage is calculated by multiplying the dielectric strength of the material times the thickness of the film.
15000 V
Thermal Properties
Temperature Resistance
Temperature Resistance
Temperature resistance is the maximum temperature that the material or product can withstand for a period of time.

The temperatures listed should be considered as guidelines for an operating temperature of about 30 minutes. Typically, the material can withstand much longer times at temperatures about 20°C lower and can withstand much higher temperatures for short, intermittent times.

Other Properties
RoHS Compliant
RoHS Compliant
RoHS is a product level compliance based on a European Union Directive which restricts the Use of certain Hazardous Substances in Electrical and Electronic Equipment (RoHS).

Products compliant with this directive do not exceed the allowable amounts of the following restricted materials: lead, mercury, cadmium, hexavalent chromium, polybrominated biphenyls (PBB) and polybrominated diphenyl ethers (PBDE), with some limited exemptions
