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
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.
38.1 µm
Chemistry Type Polyimide
The color
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.
25.4 µm
Release Liner
Release Liner
A paper or plastic-based film sheet used to prevent a sticky surface from prematurely adhering
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.
Special Layer None
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.
63.5 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.
26 Oz/in
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.
55 %
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.
89 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.
>6000 V
Dielectric Strength
Dielectric Strength
Dielectric strength is measured in kV per mm and is calculated by the Breakdown voltage divided by the thickness of the tested material.

Those two properties go hand in hand and while Breakdown voltage is always thickness dependent, dielectric strength is a general material property.

As an example, the dielectric strength of Polyimide is 236 kV/mm. If we place 1mm of Polyimide between two electrodes, it will act as an insulator until the voltage between the electrodes reaches 236 kV. At this point it will start acting as a good conductor, causing sparks, potential punctures and current flow.
236 kV/mm
Volume Resistivity
Volume Resistivity
Volume resistivity, also called volume resistance, bulk resistance or bulk resistivity is a thickness dependent measurement of the resistivity of a material perpendicular to the plane of the surface.
1.0x1013 Ohms⋅cm
Dielectric Constant
Dielectric Constant
Dielectric Constant (k), commonly known as relative permittivity, is a number relating the ability of a material to carry alternating current to the ability of vacuum to carry alternating current.

It determines the ability of an insulator to store electrical energy and is the ratio of electric permeability in vacuum against the electric permeability of a material.

The lower the dielectric constant (κ) and dissipation factor, the less energy is absorbed from an electric field, making it a much better insulator.

It is a dimensionless property that can be affected by various factors such as the
thickness uniformity of a material, insufficient contact between the sample and electrodes, water adsorption and contact resistance.
Dielectric Constant @ 23 ˚C/1 kHz 3.9
Dissipation Factor
Dissipation Factor
Dissipation factor is commonly known as loss tangent or tan delta.

It is a ratio of the loss index and the relative permittivity and it measures the inefficiency of an insulating material to maintain energy (that otherwise dissipates in the form of heat). The lower the factor, the better the insulation.

It is the reciprocal of the quality factor and always refers to a specific temperature and frequency.
Dissipation Factor @ 23°C /1 kHz 0.0036
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
VOC-Free (100% solids content)
VOC-Free (100% solids content)
VOC means Volatile Organic compound. VOCs are evaporating molecules and are literally everywhere around us. Our scents are volatile organic compounds, most of the things that we smell are VOC etc. So what do we mean when we state that a product is VOC free?

A VOC free product, according to the FTC is one where:

1)VOCs have not been intentionally added to the product.

2)The presence of VOCs at that level does not cause material harm that consumers typically associate with VOCs, including but not limited to, harm to the environment or human health.

3)The presence of VOCs at that level does not result in concentrations higher than would be found at background levels in the ambient air.

Additional Information

  Typical Applications


Comparing with Kapton tape with acrylic adhesive (PIT1A series), silicone adhesives tape can withstand higher temperature range as compared to acrylic adhesives, which provide a wider appilication range. Acrylics have the property of being more brittle and as such they can crack at extremely low temperatures too. Generally speaking, the acrylic adhesive will have higher adhesion at mid-range temperatures (0°C to 100°C), but silicone adhesives have higher adhesion at lower temperatures (under 0°C) and higher temperatures (above 100°C). PIT1S-Series are suitable for continous cold and high temperature environments, typical applications are:

  • Masking against chemicals, heat and other hash conditions
  • PCB masking for wave solder and solder reflow process
  • Protective layer, ground, barrier and cross over insulation for electrical components like bobbin, toroidal coils, etc.
  • End-turn bunding and connection insulation for small motors, etc.
