Polyimide Tape Manufacturer & Supplier in India
Kapton polyimide tape is a name that is widely known as polyimide tape, which happens to be a highly respected product among the variety of high temperature insulating tapes used in the electrical and electronics industry. This is an electrically insulating tape made from polyimide films that is suitable for use in situations where resistance to heat and high temperatures is required.
Harnawa Inc. is an established polyimide tape supplier and manufacturer based in India and being an ISO Certified company, we supply internationally certified, quality tested Polyimide Film Tape to a wide range of industries in India including motors, transformers, electronics, and industrial sectors – thereby reinforcing our status as one of the recognized Electrical Insulation Materials Manufacturers in India.
What is Polyimide Tape?
Polyimide tape is made up of polyimide film, which is the same raw material that is commonly referred to as Kapton. This type of polyimide film is coated with a high temperature adhesive on either of its sides. The polyimide film itself has become famous in the electrical and electronics industry due to its excellent thermal stability and dielectric characteristics.
Kapton Polyimide Tape — Understanding the Name
The Kapton trademark is an example of a brand name that has been historically related to polyimide films, similar to Bakelite being the brand name related to phenolic resins. Common usage in industries uses terms such as “Kapton polyimide tape” and “polyimide tape” synonymously when referring to a group of tapes made from polyimide film.
Double Sided Polyimide Tape
The polyimide tape can be coated with adhesive either on one side or on both sides. In case of double-sided polyimide tape, special heat resistant adhesive is applied on both sides of the polyimide material, enabling it to act as an adhesive for bonding two surfaces while still providing good thermal and electrical insulation properties.
Technical Specification Overview
The Polyimide Tape from Harnawa Inc. is manufactured according to the following specifications:
- Class of Insulation: F
- Temperature Range: 155°C
- Thickness: 0.10 mm to 0.76 mm
- Width: 6 mm to 1000m
Polyimide Film Tape Construction
Polyimide film tape consists of a thin but strong polyimide film, which is coated with an adhesive and then cut into the required dimensions after drying. This makes the tape very stable in its dimensions, tear-resistant, and flexible, so that it can wrap around small components. All of these qualities are vital for masking and insulation work in printed circuit board production and electronics manufacturing.
Key Properties
High Heat Resistance – The film is naturally appropriate for use in high temperature environments, as it maintains its physical and dielectric strength where others will deteriorate.
Dielectric Insulator – An effective insulator, suitable for use in electronic and motor windings.
Chemical Resistance – Highly resistant to a variety of chemical solvents that may be used in manufacturing procedures such as soldering and wave-soldering masking.
Dimensional Stability – Maintains dimensional stability through thermal cycles, which is necessary in repeatable manufacturing procedures.
Precisely Cut Tapes – Cut into precise widths for masking, splicing and component applications.
Applications of Polyimide Tape
Polyimide tape is widely specified across:
- PCB Assembly – masking of parts and pads while doing wave soldering and reflow assembly process
- Motors & Generators Winding – insulation of windings while building motors and generators
- Electronic Assembly – splicing, masking, and high-temperature insulation application
- Transformer & Coil Construction – insulation of layers in high-temperature winding applications
- Industrial High-Temperature Applications – any place where there is a requirement for thin high-temperature insulating tape
Completing the Insulation System
Polyimide tape is frequently used alongside other insulation materials to build a complete dielectric system for motors, transformers, and electronics manufacturing:
Sourcing all of these materials from a single certified supplier ensures compatibility, consistent quality standards, and simplified procurement for OEMs and electronics manufacturers.
