About Kapton Tape
Kapton Tape consists of an aromatic substance called dipropylene, which is known to be one of the strongest adhesives known to man. It has unique properties that make it special. Basically, it is a two-part epoxy, consisting of a core consisting of one molecule of dipropylene, and an outer layer composed of smaller rings of the same dipropylene. Due to its chemical makeup, it is unable to bond with any other substance, including silicone, formaldehyde, and boron. Because of this, it is commonly used in thermal and chemical bond-making processes, such as reinforcing thermoset metal sheets, making paper, rubber, and plastics, and developing friction stirrers and seals.
Kapton tape is made by DuPont, a renowned company known for its long history in the manufacture of paper, dry film, thermal insulating materials, synthetic coatings, bonding glue, thermoplastic materials, sealants, thermoforming, and plastics. Its most famous invention is the thermal or conductive tape, which is used both in industries and in arts. This type of material is used in everything from labels on plastic containers to the lining of digital cameras and microphones. The extreme temperature resistant and heat resistant qualities of the material make it ideal for applications requiring high temperature resistance, such as electronics and aerospace manufacturing. In addition, the polyimide core of the material makes it ideal for thermal and chemical bonds.
Kapton tape is a very strong and durable tape, able to withstand high temperatures. It is also capable of withstanding pressures up to 5 atmospheres (at atmospheric pressure) at ambient pressure, as well as specific stresses and strains. The material can be found in a variety of different compositions, depending on the particular use, which can include high-vibration, damp, or impact resistance. This versatility allows manufacturers to diversify their applications. By using multiple layers and types of kapton tape, some manufacturers have been able to create an adhesive that is able to stand up against heat, grease, moisture, as well as wear and tear.
What is Kapton Tape Used For?
Kapton tape has many additional benefits over other similar tapes. Most commonly, it is used for cosmetic or labeling purposes, either attached to an existing surface, or applied to a surface after it is already attached. It is often used to protect delicate surfaces, such as computer screen panels. Kapton tape can also be used to create an airtight seal around piping. These tapes are sometimes used as connectors on plumbing joints, in line with copper pipes and metal fixtures. They are even seen on some safety helmets to connect wires and clips.
When used as an adhesive kapton tape can be mixed with high temperature silicone adhesive for extra strength. Silicone is a good medium for adhesives because it has excellent adhesive strength and resistance to abrasion, moisture, and heat. However, these properties don’t mean that the type hn film is insoluble when mixed with the other material. Kapton tapes can be separated from each other using heat or a chemical agent that changes the molecular structure.
The most common type of kapton tape is one mil thick. One mil refers to one billionth of an inch, which is fine for electrical insulation. This is also the thickness at which it will be most effective for applying to a surface. The most popular applications for one mil tapes are on electrical boxes and circuit boards. Electrical insulation can benefit from a thick enough layer, as it provides extra resistance to electrical currents. This is especially true for applications in which there are frequent changes in current levels or high power dissipation.
Another type of kapton tape is called polyimide tape. Like one mil, it is made up of a hexagonal array of similar sheets. However, polyimide tape has a higher dielectric strength than typical kapton tape, making it useful for application in high-power electronics and for use in air conditioning systems. Its thickness can vary, however, from one six-inch piece to eighteen inches. Most of these products are good for applications in up to thirty-two inches, but they can also be purchased in forty-eight and fifty-six inch widths.
The Bottom Line
You can Buy Kapton Tape from Creative Global Solutions where it is available in rolls of a variety of sizes and is often packaged in groups of four to six. Standard rolls of this material are typically between twenty-six and twenty-eight inches wide. Small rolls of this product are sold in packages of one hundred feet or less, while larger packages range between ten and twelve feet wide. The most common application for kapton tape is adhesive tape that is used to install light fixtures, such as ceiling fixtures. It may also be used to repair damaged parts of electronic equipment or to patch leakages.
