- Non-silicone, acrylic adhesive
- 11,000V breakdown voltage
Product Description
LINQTAPE PIT2A-RL-Series Polyimide Tape is a high-temperature resistant polyimide tape on a 3mil PET Release Liner. It is designed for high temperature temporary bonding applications and it removes cleanly without adhesive residue after exposure to heat or chemicals. It may also be used in electrical insulation applications that require Class H Tape grade.
Product Applications
The 2-mil thickness makes it suitable for applications that require more mechanical strength and breakdown voltage than a standard (1-mil thick) polyimide film. Having an acrylic adhesive makes it suitable for higher temperature applications that cannot use silicone adhesives. Finally, being on a liner makes it suitable for applications that require the film to be die-cut.
Applications:
- High Temperature Wafer Dicing Tape
- Die-cut polyimide parts
PRODUCT FEATURES & BENEFITS:
- 2-mil polyimide thickness
- Acrylic Adhesive
- Linered
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 | Acrylic | ||||
| 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 | ||||
| Color Color The color | Amber | ||||
| 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 | Single Release Liner | ||||
| 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-Sided | ||||
| 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. | 88.9 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 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. | 50 % | ||||
| 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. | 54 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. | >11,000 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. | 197 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 | ||||

| 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. | 155 ˚C | ||||

| 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 | ||||
| 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. | Yes | ||||
