POLYIMIDE FILM TAPE

Get to Know
Polyimide Film Tape

Polyimide tape is a high-temperature resistant engineering film tape, using a Polyimide film as its core, coated with silicone or acrylic adhesive. It is ideal for high-heat masking, electrical insulation, and protecting workpieces. Its key features are thinness, strength, good form retention, and clean peel-off to minimize adhesive residue on the workpiece.

✔ Key Features: Excellent high-temperature resistance (continuous use up to approx. 260°C in industrial applications), superior electrical insulation (high Dielectric Strength), resistance to chemicals/solvents, smooth film surface for sharp masking edges, consistent adhesion and clean removal without residue, thin profile for excellent conformability. Available with silicone/acrylic adhesive options and various widths.

✔ Why It's Interesting: Covers diverse applications such as masking during Reflow/Wave Solder, Powder Coating mask, Motor/Transformer coil insulation, Lithium Battery cell wrapping, PCB repair, and 3D printing requiring heat resistance—it helps reduce scrap, maintains surface cleanliness, and enhances process stability.

Key Factors for Selecting Polyimide Tape

 

5 Essential Points to Know Before Choosing the Right Polyimide Tape for Your Application

1
Operating Temperature
Select tape based on operating temperature, e.g., for soldering or powder coating, use tape resistant to 260°C or higher to prevent film melting or adhesive degradation.
2
Adhesive Type
Silicone adhesive is suitable for high-heat applications and clean removal, while acrylic adhesive offers stronger adhesion for general surfaces.
3
Tape Thickness
Thin tape is suitable for detailed work like PCBs, while thicker tape provides better edge protection and insulation strength.
4
Substrate Surface
Check the surface such as metal, plastic, or glass to select an adhesive that adheres well and peels off without leaving residue.
5
Budget and Standards
Select a brand that meets RoHS/REACH standards and fits the budget, considering roll length and minimum order quantity.
