Among the many different types of adhesive tape, PET tape is considered to be a good choice for lithium-ion battery manufacturing. Polyester film has high tensile strength, chemical resistance, and durability. It also provides superior bonding to treated materials. This is because the polyester backing is highly conformable, resistant to sharp edges, and offers superior dimensional stability. It also resists damage from oil, solvents, and acids. It is the preferred substrate for a variety of electronic and mechanical applications.
For lithium-ion batteries, it is important to have a protective layer that is not only effective in sealing the internal cell but is also capable of protecting the cell from sacrificial damage due to high temperature or corrosive environments. This is facilitated by a composite PET adhesive tape. The composite PET adhesive tape consists of a thermoplastic layer, which provides excellent heat-sealing capabilities. The upper layer consists of a PET polyester film, while the lower layer consists of a polypropylene film. The polyester film has a high shear and tears strength and a smooth surface. The polyester film is also resistant to UV light and other harmful elements.
The acrylic adhesive is coated evenly on the PET polyester substrate layer. The adhesive is designed for a variety of uses, including fixing nameplates, membrane switches, and bonding nameplates to other surfaces. The adhesive is also a good candidate for bonding to silicone-treated surfaces. The acrylic adhesive has some interesting properties, such as superior UV resistance and a fair initial strength.
The polyester film is also designed to offer scratch-free release coating. It has a high cross-web consistency. It is also a good insulator, providing electrical insulation. It is commonly used in packaging and for electronic applications. It is available in a variety of adhesives, such as silicone and rubber. It is also a good candidate for bonding and splicing.
Polyester tape is also used as a splicing or masking tape, especially in the field of high-temperature masking. Polyester film has a wide range of applications, including automotive, electronics, and packaging. Its main attributes are its high initial adhesion, resistance to chemicals, and high aging resistance. Moreover, polyester film has a low price, making it a popular choice for low-cost applications.
Another type of polyester film is double-sided adhesive tape. This is composed of a PET polyester film and a silicone or rubber pressure-sensitive adhesive. The adhesive is coated on both sides of the PET film. It is also referred to as a double-sided acrylic adhesive or sheathing tape. The double-sided tape is designed to be reusable and can be easily die-cut. It is also available in a variety of colors. The shelf life of a clear double-sided PET adhesive tape is two years. It is best stored at room temperature.
Polyester (PET) tape with silicone adhesive is commonly used in spray coating, electroplating, and high-temperature masking. It is also found in the lamination section of the lithium-ion battery assembly.
