High Temperature Polyimide Tape | 400°C Heat Resistant Insulation Tape for PCB Circuit Board Battery Repair

This high temperature polyimide tape provides reliable insulation and protection for electronics repair and assembly. With a maximum temperature resistance of 400°C (752°F), it is designed for soldering, PCB protection, and battery wrap applications where standard tapes fail.

The tape uses a polyimide film backing with high temperature resistant silicone adhesive. It delivers strong adhesion without leaving residue after removal. Each roll measures 35 meters in length, giving you plenty of material for multiple projects.

This tape resists solvents, radiation, and electrical current. It helps you protect sensitive components during soldering, insulate transformer coils, and secure battery packs. The brown color makes it easy to see placement on circuit boards.

Whether you are repairing a phone motherboard or insulating a motor, this tape handles the heat and keeps your work clean and safe.

Key Features and Benefits

- 400°C short-term heat resistance that protects components during high temperature soldering and rework

• Polyimide film with silicone adhesive that leaves no sticky residue when removed

• 7kV voltage resistance that provides reliable electrical insulation for circuit boards and batteries

• 35 meters per roll that gives you long-lasting supply for multiple repair jobs

• Solvent and radiation resistance that maintains performance in harsh workshop environments

• 6 N/25mm adhesion strength that keeps tape securely in place during use

Who Is This For

- Phone repair technicians who need to protect PCB components during soldering and rework

• Electronics hobbyists and makers who build or modify circuit boards at home

• Battery pack assemblers who require reliable insulation for lithium cell wrapping

• Motor repair professionals who need heat resistant tape for coil insulation and bundling

Usage Scenario

Mark was replacing a damaged charging port on a smartphone. He needed to protect nearby components from the heat of his soldering iron. He cut a strip of this polyimide tape and placed it over the adjacent IC chips. The tape stayed in place through the entire soldering process and peeled off cleanly without any residue. His repair worked on the first try, and he saved time not having to clean up adhesive mess.

Micro Comparison

Standard electrical tape cannot handle the 400°C temperatures found near soldering irons and hot air stations. This polyimide tape is specifically designed for those conditions. Unlike cheaper alternatives, it uses a quality silicone adhesive that does not leave sticky residue after removal, which protects your circuit boards from contamination.

Questions and Answers

Question: Can this tape be used for battery insulation?

Answer: Yes, it works well for wrapping and insulating lithium batteries and protecting battery terminals during assembly.

Question: Does the tape leave sticky residue after removal?

Answer: No, the silicone adhesive is designed to peel off cleanly without leaving residue on most surfaces.

Question: What is the difference between short-term and long-term temperature resistance?

Answer: Short-term resistance (400°C) is for brief exposure during soldering. Long-term resistance (300°C) is for continuous use in hot environments.

Question: Can I use this tape for masking during PCB gold plating?

Answer: Yes, it is commonly used as a gold finger tape to protect PCB contacts during plating and soldering processes.

Question: Is this tape suitable for transformer coil insulation?

Answer: Yes, it works well for insulating transformer coils and bundling motor windings due to its electrical and heat resistance.
