High Temperature Polyimide Film without Adhesive

High-Temperature Polyimide Film – Adhesive-Free Heat Insulation up to 400°C

🔥Our high-temperature polyimide film is engineered for extreme environments. Made from pure, adhesive-free polyimide material, this insulation film performs under continuous heat exposure up to 400°C, making it ideal for aerospace, electronics, and high-precision industrial applications where thermal stability and cleanliness are critical.

Whether you’re working with sensitive electronic components or high-temperature manufacturing equipment, this film delivers outstanding electrical insulation, dimensional stability, and chemical resistance—ensuring long-term reliability and performance.

⚙️ Built for Harsh Conditions – No Adhesive, No Compromises

Unlike standard tapes or films, our polyimide insulation sheet contains no adhesive layer, making it the preferred choice where outgassing or residue must be avoided. Its 0.15mm thickness provides enough mechanical strength while staying ultra-flexible for wrapping, masking, or layering.

Even under rapid heating and cooling cycles, the material remains dimensionally stable, so it won’t warp, curl, or delaminate. This ensures components remain protected and your processes run smoothly—with less downtime and rework.

🧠 Precision Fit, Minimal Waste – Custom Sizes Available

Every project is different. That’s why we offer custom fabrication options for your polyimide insulation needs. From standard sheets, rolls, and tape formats, to custom die-cut shapes or CNC-cut parts, we help you get exactly what your process requires—no more, no less.

This means less material waste, faster installation, and lower total costs, especially for clients managing large-scale production or sensitive prototyping work.

🌍 Applications Across High-Performance Industries

Our polyimide film is trusted across demanding industries where reliability is non-negotiable:

• Aerospace & Aviation: Wire harness insulation, thermal barrier films, sensor wraps

• Electronics & PCB Assembly: High-temp masking, solder masking, coil insulation

• Automotive Manufacturing: Powder-coating masking, cable protection

• Precision Equipment: Etching masks, plasma spraying shields, semiconductor packaging

If your project involves extreme heat, precise tolerances, or delicate electronics, this is the insulation material you can depend on.
