What is Polyimide Tape?
Polyimide tape is a high-performance adhesive tape made from polyimide film, renowned for its exceptional heat resistance, electrical insulation, and chemical stability. It is widely used in industries such as electronics, automotive, and energy storage, where reliability under extreme conditions is critical.
Key Features:
- Heat Resistance: Withstands temperatures up to 400°C, making it ideal for soldering, masking, and insulation in harsh environments.
- Electrical Insulation: Provides excellent dielectric strength, ensuring safety and performance in electronic assemblies.
- Chemical Resistance: Resistant to solvents and processing chemicals, maintaining integrity during manufacturing processes.
- Low Outgassing: Suitable for high-vacuum and cleanroom applications.
Applications of Polyimide Tape
Polyimide tape is used in a variety of advanced applications, including:
Battery Manufacturing:
Insulation and protection for all battery types (cylindrical, prismatic, and pouch), particularly medium- and large-sized EV batteries where safety is critical (e.g. tab cover, jelly-roll fixing, cell-case wrapping). The superior insulating, heat-resistant, and chemical-resistant properties of polyimide film help prevent current leakage and enhance safety. Available in a wide range of thicknesses, these films provide optimized solutions for diverse application needs.
Semiconductor Packaging:
Used as QFN (Quad Flat No-lead) backside film tape, polyimide tape prevents resin leakage during molding and ensures stable wire-bonding ability.
PCB Manufacturing:
High-temperature masking tape for wave soldering, protecting circuit boards during gold contact processing, and leaving no adhesive residue.
Cable and Wire Insulation:
Polyimide-wrapped wires are used in motors, transformers, and aerospace applications for their high cut-through and abrasion resistance.
Polyimide Labels: High-Temperature Identification Solutions
Polyimide labels are specialized labels made from polyimide film, designed to withstand extreme temperatures and harsh chemicals. They are commonly used for component identification, traceability, and compliance labeling in electronics manufacturing.
Key Features:
- Heat Resistance: Survives temperatures up to 400°C, suitable for PCB labeling during soldering processes.
- Chemical Durability: Resistant to solvents and cleaning agents used in electronics manufacturing.
- Printability: Compatible with high-performance resin-based ribbons for clear, durable printing.
- Removable Overlays: Polyimide overlay tapes are available for additional protection and re-labeling needs.
