Double sided PET tape is a versatile, multipurpose tape that has been used in many different applications. It comes in a variety of widths, lengths, and thicknesses, as well as several different adhesives, materials, and backings.
It can be found in a variety of industries including POS, communication, and retail, for bonding or final assembly of displays. The polyester (PET) backing material combines with either silicone or acrylic adhesives, providing a high-performance bond to various substrates, as well as excellent resistance to plasticizers and oil.
Depending on the type of adhesive, it can be used for general bonding applications, sealing, photo stacking, light shopping bag making, and nameplates, as well as the film switches mounting fixing, etc. It is available in both solvent acrylic and synthetic rubber adhesives.
Double sided PET tape can also be used in automotive applications where they replace rivets and fasteners to hold panels together. These tapes are designed to adhere to a wide range of surfaces, from paper, leather, and textiles to metal, glass, plastic, and composite materials. They are also durable, allowing them to be exposed to the elements without deterioration or delamination.
For the most part, these tapes are a very cost-effective alternative to glue or other permanent adhesives for light bonding jobs. But it is important to be aware that they may peel or crack under certain conditions.
There are several factors that you should consider when choosing a suitable tape for your application, including the surface energy of each substrate. The higher the surface energy, the more likely it is for the tape to stick.
Another consideration is the temperature resistance of the tape. This is particularly important when you are working in cold environments or very hot conditions where the tackiness of the adhesive tape can cause problems.
If your application requires a temperature-resistant bond, choose a tape with a low tack. This is especially important if the surfaces you are bonding are treated or coated, as these can affect the adhesion of the tape to the surface.
This is also a good time to check the thickness of the tape and the type of surface you are attaching it to. Generally, thinner tapes are more prone to pulling off, whereas thicker tapes are easier to work with.
Ultimately, it is up to the manufacturer to decide which type of adhesive tape will work best for their particular application. It is essential that they understand the type of materials used in a device, as well as any additional processing requirements that are necessary for a long-term application.
