Various types of Kapton adhesive tapes


Kapton  polyimide are indeed the best choice to produce innovative design solutions, making their presence felt  in various industries like consumer electronics, solar photovoltaic and wind energy, aerospace, automotive and industrial applications. Additionally, this exhibiting a high dielectric strength leaves no residue on account of the Silicon adhesive protection, conforming to MIL-P-46112, TYPE I.

The following are the types of Kapton tapes classified on the basis of their thickness, with their inherent properties and applications being the same.

  • 1 Mil Kapton Tapes
  • 2 Mil Kapton Tapes
  • 5 Mil Kapton Tapes

Double Sided Polyimide tapes – RoHS compliant:

Double Sided POLYIMIDE TAPE is made of 1 mmpolyimide tape with 1.5 mm of silicone adhesive coating on each side, which can withstand temperatures of up to 500°F/(260°C).

These polyimide tapes with high dielectric strength; offer an excellent performance in electrical and thermal insulation. Being resistant to puncture and tears, these tapes demonstrate an excellent thermal endurance, conforming to MIL SPEC MIL-P-46112 Type I.

Varied applications of these double sided polyimide tapes are as follows:

  • High Temperature Masking
  • Best insulator material for  Transformers, Motors and Coils
  • Used in Powder Coating
  • Offers protection to circuit board gold finger contacts during wave soldering
  • Used in Solar Panels

ESD Tapes – RoHS Compliant:

ESD Tapes are also called as Clear ESD Cellulose Tapes, or ESD Printed Tape. These are made of a 2 mm clear cellulose acetate material with a rubber based adhesive.

Printed with an ESD symbol, these tapes sport a bold "Anti Static" print.

With a tensile strength of 90 N/25mm, these tapes are available in 3" core, with 108 feet in length. Withstanding temperature range is between 32°-150°F. These meet Static Decay Specifications of MIL-B-81705 with a charge decay of <.014 second.

These tapes are predominantly used in the following situations

  • Electronic assembly
  • ESD packaging containers
  • Identification of Static sensitive products
  • Holding ID DIP tubes
  • To seal ESD Bags
  • Used in the shipment of ESD sensitive devices

Clear ESD Tapes - RoHS Compliant:

These are another category of Clear ESD Tapes also known as ESD Cellulose Tapes, finding similar applications as the ESD tapes. While the thickness, temperature range and length are same as clear ESD tapes, the Clear ESD tapes demonstrate a tensile strength of 24lbs/inch, meeting specification CID-AA-113B, Type 1, Class A and ANSI ESD S20.20 standards.

Applications:

Some of the primary uses are in electrical applications such as coil insulation, capacitor and transformer wrapping or insulation, magnetic wire insulation, and in gold leaf masking during wave soldering.  It is also used as a very high temperature mask during powder coating applications. Polyimide tape is also used in the auto industry for wrapping switches, diaphragms, sensors and coils in seat heaters. The aerospace industry uses Polyimide tape primarily for insulation of aircraft and spacecraft wings. Polyimide tape can be laminated, metalized and punch formed; and these capabilities make it a candidate for converting to different shapes and sizes. Kapton POLYIMIDE TAPE is commonly used as a wire and cable wrap as well as to protect electrical components during soldering. It is effective for both hand-soldering and mass soldering applications, such as wave soldering. In the electronics industry, Kapton tape is applied to circuit boards before wave soldering to shield gold fingers from the solder material and prevent unwanted electrical connections.

Low Static Kapton Discs make for innovative design solutions possible in an array of industries such as consumer electronics, solar photovoltaic energy and wind energy; automotive, aerospace, as well as industrial applications. They have set a high standard in the industry for more than 46 years in terms of their high performance, reliability, and durability.
