Polyester adhesive tape, also called PET tape and splicing tape, is manufactured from single or double-sided polyester film coated with either acrylic, rubber, or silicone adhesive. It is highly resistant to moisture, oils, and various chemicals, and has excellent peel strength, shear strength, tensile strength, and dimensional stability.
A broad range of polyester tapes is available to meet specific adhesion and application requirements. They can be used for many different purposes such as bonding, masking, insulation, and mounting. They are often used in applications such as electronics, composite bonding protection, printed circuit board fabrication, and electrical insulation.
The physical and thermal properties of different types of polyester tape are determined by the substrate, the adhesive coating, the adhesive cure technology, and the backing or carrier material. The dimensional specifications of these materials also play an important role in determining the performance characteristics of the tape product.
Single-sided polyester tapes consist of a thin polyester film containing an acrylic, silicone, or rubber adhesive on one side. They can be applied to a wide variety of surfaces such as glass, plastic, and metal. The adhesive is applied in a liquid or paste form and cured by air, oxygen, or thermoplastic. These adhesives become tacky or sticky when they are heated.
These adhesives may soften, melt or harden repeatedly by heat and can be reactivated with air or oxygen. They are available as a fast set, delayed set, and pressure-sensitive type. They can be used as an alternative to liquid resin adhesives, hot melt adhesives, fasteners, solders, braze, and welding.
Double sided polyester tapes consist of a thin adhesive film coated with an acrylic, silicone, or rubber adhesive on both sides of a carrier or backing material. The carrier or backing material functions to stabilize the adhesive, improve handling and provide removability.
Several different types of polyester adhesive tape can be slit to custom widths or cut into parts that are finished on individual sheets or wrapped on rolls. China Heat Resistant Tape manufactures a variety of these products to meet the needs of our customers.
Some polyester adhesive tapes are formulated with acrylic or rubber-based adhesives that have good initial adhesion, excellent shear strength, and high UV resistance. They are cheaper than other types of polyester tapes that use silicone adhesive formulas.
Polyester adhesive tape is widely used in the automotive and electronics industries for a wide variety of applications including bonding, masking, insulation, and mounting. They are especially helpful in masking metal surfaces during caustic or acid chemical milling, etching, and anodization baths. They can also be used for sealing and affixing plastic bags and containers for temporary adhesion purposes.
