Insulation film for production lines requiring heat and voltage resistance — Send us your specs, and our engineering team will point out the exact model for your actual process, so you don't overpay.
What is Plastic Insulation Tape?
Film tape that performs two functions simultaneously: blocking electrical current and resisting high temperatures without shrinking or wrinkling. Divided into 2 main families, differing by IEC 60085 Thermal Class and price range.
*Class B / Class H refers to the continuous operating temperature according to the IEC 60085 insulation class system — actual values for each model depend on the manufacturer's Technical Data Sheet.

Important Note: Insulation tape is a composite material, not a safety device that replaces standard protection systems. Electrical and thermal applications directly affect worker safety and equipment lifespan. Before finalizing specs, you should check the Dielectric Breakdown value and temperature range from the latest TDS to ensure they meet project requirements, and have the responsible engineer approve it. Information on this page is a preliminary guideline for material screening, not engineering certification for specific applications.
2 Most Reordered Models by Factories
They differ in adhesive type, which determines whether they leave a residue upon removal and what surfaces they can bond to.
*Thickness, adhesion, and temperature range vary by model and manufacturer — refer to the Technical Data Sheet for each part number.
A Single Tape Roll Determines the Quality of the Entire Batch
A roll costs only a few hundred, but if specs don't match, the whole batch is ruined — 3 things that change when using the right tape for the actual job.
Peel and Done, No Need to Wipe Off Adhesive
Heat-resistant silicone adhesive can be removed immediately after oven baking without leaving a sticky residue on the part, eliminating solvent wiping and rework.
No Electrical Leakage, No Short Circuits
Insulation films with clear Dielectric Breakdown values in the TDS for every roll. Know exactly how much voltage it can resist before buying, with UL Recognized models available.
No Need to Buy the Most Expensive, Just Buy What Fits the Job
Tell us the oven temperature and the time the part stays inside. Our engineering team will indicate whether Kapton or PET is sufficient — many applications have switched to PET to save costs without compromising quality.
*Dielectric strength and UL certification vary by model — check the Technical Data Sheet for each part number.
Who Uses This Tape, and Where?

3 Work Environments Where Ordinary Tapes Fail
But industrial-grade insulation films can handle it — and here are the material science reasons why.
High-Heat Processes
Stays in the oven throughout the baking cycle without shrinking or wrinkling. Peels off cleanly once the part cools, leaving no adhesive residue.
Chemical Exposure Areas
Resists flux and PCB cleaning solvents. Doesn't swell or peel. Adhesive won't melt or leak onto the part during the process.
Tight Space Assembly
Wraps insulation without adding thickness to the part. Fits perfectly into original slots without redesigning.
*Starting thickness and chemical resistance vary by model and manufacturer — refer to the Technical Data Sheet for each part number.
Choose the Right Tape Specs in 3 Steps
Answer these 3 questions before ordering — and get it right the first time.
Measure the actual maximum temperature the part encounters
Use Peak Temperature, not average — this number immediately determines which family to use.
Choose PET Tape
Must be Polyimide
Choose the right adhesive for the job
Ask yourself one question — does this tape need to be removed later?
Silicone Adhesive — Must be removed
Acrylic Adhesive — Permanent
Check the required electrical breakdown voltage
See how many volts the part must withstand, then select a thickness that offers a higher Breakdown Voltage with a safety margin — this value is specified in every model's TDS.
*Temperature range and Breakdown Voltage vary by model and manufacturer — refer to the Technical Data Sheet for each part number.

Not Sure Which One to Use? Send Us Your Application Conditions and Our Team Will Help.
Tell us the temperature, surface type, how long the tape stays on the part, and the removal method — with this, our engineering team can provide a preliminary spec evaluation and propose the right model.
