2. Analysis of Current PI Tape Production Process

2.1 Detailed Description of Production Stages

The production process of PI (Polyimide) tape is a complex and precise manufacturing procedure that involves multiple stages, each contributing to the final product's quality and performance. The initial stage is raw material preparation, where high-quality polyimide films serve as the base material for the tape. These films are typically derived from aromatic dianhydrides and diamines through a polycondensation reaction followed by imidization, ensuring excellent thermal stability and mechanical properties

. Subsequently, the prepared raw materials are subjected to the coating process, in which adhesive layers are applied to one or both sides of the polyimide film. This step requires precise control of coating thickness and uniformity to guarantee consistent adhesion performance. After coating, the tapes enter the drying stage, where solvents in the adhesive are evaporated through thermal treatment. The drying process is energy-intensive and often involves high-temperature ovens to achieve efficient solvent removal

. Finally, the dried tapes are slit into specific widths according to customer requirements, followed by winding and packaging for shipment. Each of these production stages demands stringent quality control measures to meet the industry standards for PI tape applications, such as in electronics and aerospace industries.

2.2 Identification of Non⁃Green Aspects

Despite the advanced nature of PI tape production, several aspects of the current process do not align with green and low-carbon manufacturing principles.
