Know Before You Choose

What is Kapton Tape?

A tape utilizing Polyimide film as its base material, paired with silicone adhesive. Designed for high-temperature applications and masking to protect specific parts during production.

 
✓

Withstands High Heat

Polyimide film has excellent heat resistance. Ideal for soldering, baking, and processes that standard tapes cannot endure.

✓

Targeted Protection

Masks areas that must not be exposed to heat, coatings, or chemicals, such as contact points on a circuit board.

✓

Clean Removal

Silicone adhesive is designed for temporary bonding. Peels off easily when the job is done, reducing the chance of adhesive residue.

When Standard Tapes Fail

Why Regular Tapes Aren't Enough

Different tapes are designed differently. Using the wrong type for hot or chemical applications often results in wasted time on rework.

✕

Adhesive Softens Under Heat

Tapes not designed for high temperatures may peel off or lose adhesion during baking and soldering.

✕

Leaves Residue After Peeling

Requires an additional cleaning step, risking damage to the workpiece surface.

✕

Wasted Time on Rework

When issues recur in the production line, the cost of wasted labor and time is often much higher than the tape itself.

Real-World Applications

What Applications Can It Be Used For?

From PCB assembly lines and paint spray booths to 3D printing, polyimide tape is used to protect specific parts during processes involving heat or chemicals.

 
 

Electronics & PCBs

Masks critical points on the board, preventing heat and solder flux from entering unwanted areas.

Gold Finger Masking Wave Soldering
 

Painting & Coating

Masks specific spots that must remain free of paint or powder coating, and withstands oven temperatures.

Powder Coating Paint Masking
 

3D Printing

Applied to the print bed to ensure strong adhesion, resists heat from the heated bed, and peels off easily when printing is done.

Print Bed Adhesion FDM Machines
 

Automotive & Industrial

Protects components exposed to heat or chemicals, while acting as an electrical insulator.

Automotive Parts Electrical Insulation

Choose the Right Fit

Check These 3 Factors to Choose the Right Model

No single tape fits all jobs — tell us just these 3 things, and our technical team can instantly point you to the right model.

 
01

Temperature & Duration

How hot is the job and for how long? E.g., quick soldering or baking for several minutes. Both affect the suitable model.

02

Surface & Chemicals

Is the surface smooth or rough? What fluids or coatings will it touch? Choose an adhesive that grips well and truly resists.

03

Size & Thickness

Narrow for detailed work, wide for covering large areas. Choosing the exact fit for the job reduces waste.

Additional Services

Custom Cutting (Slit / Die-cut)

Available in multiple widths and thicknesses, cut to perfectly fit your job — No need to buy excess, zero waste.

How to Use

Things to Know Before Use

  • 260°C is a general reference value. The actual usable limit depends on the model, thickness, and heat exposure duration. Always refer to the specific model's TDS.
  • For electrical safety-related work, refer to the Dielectric Strength and certifications like UL for that specific model. Always have a responsible engineer approve the specifications before actual use.
  • We recommend testing on actual workpieces before ordering for mass production, as surfaces, chemicals, and heat cycles vary across factories.
  • Peel the tape off once the workpiece has cooled down, and store rolls in a dry place away from sunlight to preserve adhesive shelf life.

Information on this page is a basic guideline for material selection, not engineering specifications for specific applications. Please request the full TDS from our team before defining specs in production documents.

Frequently Asked Questions

Common Customer Questions

 
What is Polyimide Tape (Kapton Tape)?+
An industrial grade adhesive tape made from polyimide film coated with silicone adhesive. It is highly heat and chemical resistant, and peels off cleanly without leaving residue. Widely used for masking and protecting components in the electronics industry.
What is the maximum heat resistance temperature?+
Generally, it can withstand continuous heat up to about 260°C, making it suitable for Wave Soldering and baking processes. The actual practical limit depends on the model, thickness, and exposure time. We recommend referring to the chosen model's TDS.
Does it leave adhesive residue when peeled off?+
Generally, it peels off cleanly by hand because it uses a silicone adhesive designed for temporary bonding. However, if left attached for an unusually long time or used beyond the specified temperature, it might become harder to remove.
What applications can it be used for?+
Electronics and PCB manufacturing such as Gold Finger Masking and Wave Soldering, painting and Powder Coating processes, 3D printing, and automotive or industrial tasks that require insulation and heat resistance.
How to choose the thickness and size?+
Consider 3 factors: temperature and heat exposure duration, contact surface and chemicals, and the size and thickness suitable for the job site. We offer various widths and thicknesses, along with custom cutting (Slit / Die-cut) services.
Can it be used as standard electrical insulation?+
It has excellent insulation properties, but for electrical safety-critical work, you should refer to the Dielectric Strength and certifications (e.g., UL) of that specific model. Always have the responsible engineer approve the specifications before actual use.
