PIT2S-T-RL |2mil Polyimide (Kapton) Tape | Thin Silicone Adhesive with Release Liner
- 2 mil polyimide film
- 1mil thin silicone adhesive
- >11000V breakdown voltage
Product Description
LINQTAPE™ PIT2S-T-RL is a 2-mil thick polyimide film with a thin 1mil silicone pressure adhesive. This adds up to a total thickness of only 3 mil (76.2µm); something that ensures excellent adhesion and mechanical strength at high temperatures.
LINQTAPE™ PIT2S-T-RL tapes are high performance, temperature-resistant Polyimide tapes that use a polyimide film as a backing film. This backing film is the generic version of DuPont's Kapton HN film and is thin at 2mil (50.8µm) yet is just as flame retardant as its thicker counterparts. Laminated to this is a 1mil (25.4µm) thick pressure-sensitive silicone adhesive making the total thickness of the polyimide film plus adhesive only 3mil (76.2µm) thick. PIT2S-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 PIT2S-T-RL polyimide HN tapes.

Technical Specifications
| 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. | 50.8 µm |
| Release Liner Release Liner A paper or plastic-based film sheet used to prevent a sticky surface from prematurely adhering | Yes |
| 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. | Single |
| 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. | 76.2 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. | 12.7 Oz/in |
| Elongation Elongation Elongation is the process of lengthening something. It is a percentage that measures the initial, unstressed, length compared to the length of the material right before it breaks. It is commonly referred to as Ultimate Elongation or Tensile Elongation at break. | 60 % |
| Tensile Strength (Thin Film) Tensile Strength (Thin Film) Tensile strength determines the resistance of a material to break under tension and it measures how much elongating load (or tensile stress) it can handle before fracture. To make it simple, it measures how much force we have to apply when pulling apart a material before it breaks. | 88 N/cm |
| 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. | 11000 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. | 260 ˚C |
| 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 | Yes |
