Polyimide Film for Harsh Applications
Dunmore offers coating, metalizing, laminating and perforating services for polyimide film. Dunmore can provide additional functionality through engineering and converting to meet particular physical requirements for mechanical, electrical, temperature and chemical properties not inherent to standard polyimide film. Dunmore is one of the leading converters of polymide film in the world.
Polyimide Film Industries and Applications
Polyimide film is typically used in industries such as:
Aerospace - The Kapton? film is converted and layered together to make multi-layer insulation.
Automotive / Industrial - Polyimide films have excellent mechanical, electrical, temperature and chemical resistance making them optimal for demanding industries where performance is critical or harsh exposure conditions exist.
Electronics - Polyimide film is the optimal substrate for high temperature applications like the electronics industry.
Labeling - Polyimide film, with the right printable coating applied, makes an excellent choice for labels used in harsh environments.
Polyimide film is used in applications where reliable, durable performance is required, often in harsh environments. It also can be engineered and converted to meet particular physical requirements for mechanical, electrical, temperature and chemical properties.
What is Polyimide Film?
Polyimide films are used in applications where reliable, durable performance is required, often in harsh environments. Polyimide film is a lightweight, flexible polymer based material that has excellent heat and chemical resistant properties. Polyimide film can withstand temperatures ranging from -269° C to 400° C. In addition to excellent heat resistance properties, polyimide film also has excellent dielectric properties. Typical applications for polyimide film include multi-layer insulation blankets for space, flexible electronics, tapes, and various other high heat applications.
High Temperature Adhesive Polyimide Tape
Adhesive Polyimide Tape offers a combination of benefits. It is a high voltage insulation tape made of thin polyimide film. It is coated on one side with a silicone pressure sensitive adhesive which allows it to bond well to most surfaces and materials. The use of a silicone based adhesive is critically important as it allows Polyimide Tape to offer one of its greatest benefits; high temperature resistance.
This tape can withstand continuous exposure to temperatures up to 200°C, whilst still maintaining dielectric performance (actual mechanical maximum temperature rating is a little higher). When you combine this high temperature tolerance with its all-round adhesive performance, thin and highly conformable construction, solid polyimide film and economic price, you have a tape that can be used in a variety of areas.
Example Applications for Adhesive Polyimide Tape
Insulation of coils in electric motors.
Fastening heating elements.
Insulation for capacitors.
Masking for powder coating.
Bed surface for 3D printing with ABS.
Slot liner insulation.
Insulating and fastening flexible PCBs.
Magnet wire and cabling.
Interlayer insulation in motors and transformers.
Some of the many names we’ve heard over the years for this tape is Kapton Tape, adhesive Kapton, sticky Kapton and that sticky brown tape. With the possible exception of that last one, this is understandable but it is not technically correct.
