Polyimide tape

Polyimide tape is a specialty industrial tape with a polyimide (PI) film as its backing and a single-sided coating of a high-performance silicone pressure-sensitive adhesive.

Features: 1. Extremely high temperature resistance 2. Excellent electrical insulation 3. High mechanical strength 4. Excellent chemical stability

Applications: 1. Electronics manufacturing 2. Aerospace and automotive industries 3. Industrial manufacturing

Detailed description

The core composition of polyimide tape is “PI substrate + silicone adhesive.” This combination makes it one of the most heat-resistant and comprehensive film tapes on the market, designed for extremely harsh industrial applications.

Joint tape is a special tape specially used in industrial automated production lines to quickly and reliably connect the end of one roll of raw material to the beginning of the next roll of new material.

The core characteristics of high-temperature splice tapes are as follows:
1. Excellent Initial Tack: This is the most critical characteristic. The tape must be able to instantly and securely adhere to both the new and old webs, especially in high-speed “on-the-fly” splicing applications, ensuring seamless connection.
2. High Shear Strength: The splices must withstand the intense tension on the production line. The tape must possess sufficient cohesion and tack to resist these shear forces and prevent slippage or breakage during use.
3. Ultra-Thin Profile: The overall thickness of the splice must be extremely thin to ensure smooth passage through precision components such as rollers and scrapers, without compromising the quality of subsequent printing and coating processes.
4. High Temperature and Solvent Resistance: The tape must be able to withstand the high temperatures and chemical solvents encountered during the production process (e.g., in the oven) to ensure stable joint performance. Simply put, its core characteristics are “sticking quickly, not breaking, passing smoothly, and being durable”, all for the purpose of maximizing production efficiency.

In summary, the most common joint tape material combinations are “PET backing + acrylic/rubber adhesive” and “specialty paper backing + repulpable adhesive.” Manufacturers select the optimal backing and adhesive combination based on specific application scenarios, such as production line speed, tension, oven temperature, surface characteristics of the bonded material, and subsequent process requirements.

Joint tape is an essential consumable in many continuous production industries. Its main application areas include:
1. Printing Industry: Splicing paper, film, foil, and other roll materials on rotary printing presses, enabling continuous roll changes.
2. Paper & Converting Industry: Splicing large paper rolls on papermaking and coating machines is crucial for ensuring continuous production.
3. Film & Plastic Industry: Used for roll changing operations during film production, coating, and lamination.
4. Non-woven & Hygiene Industry: Splicing non-woven fabrics and raw materials such as PE film on production lines for products such as diapers and sanitary napkins.

The joint tapes provided by the company mainly include polyester tape MY36, MY26, MY28, MY27, polyimide tape KA06, and kraft paper tape KT13H.
