Description
Black Kapton Tape (Matte) is a premium high-temperature Kapton tape engineered for precision electronics and industrial masking applications. Constructed from a black polyimide film substrate with a high-temperature silicone pressure-sensitive adhesive, this matte Kapton tape delivers stable adhesion and is designed for clean removal on common smooth substrates under recommended temperature and dwell time. Optional PET or fluorine release liners are available for die-cut parts and roll formats to meet OEM assembly requirements.
Designed to withstand thermal cycling, chemical exposure and mechanical stress, this tape maintains electrical insulation and dimensional stability without leaving residue on smooth surfaces. The matte finish minimizes glare and light reflection, improving visual contrast for inspection-intensive assembly, optical alignment and masking operations. Available in custom widths (3–500 mm) and lengths (33–66 m); rolls, sheets and die-cut formats can be supplied to suit production or prototyping needs.

Test Methods & Conditions
Typical values are based on standard test methods and may vary with adhesive coat, substrate, and process conditions.
- Peel adhesion to steel: ASTM D3330 (or FINAT FTM 1), 180° peel, 25 mm width
- Tensile strength / Elongation: ASTM D3759 (tape) or equivalent industry method
- Heat resistance: evaluated by internal method (temperature and dwell time available upon request)
- Electrical tests (optional): dielectric breakdown per ASTM D149 available upon request
Features
- High-temperature resistance — Rated up to 260 °C for high-temperature masking and insulation. Suitable for typical reflow, wave solder and thermal curing processes; performance depends on process profile and dwell time.
- Excellent electrical insulation — High dielectric strength suitable for PCB assembly, transformers, motors and capacitor insulation.
- Chemical & solvent resistance — Resists common acids, alkalis, oils and cleaning solvents encountered in industrial processes.
- Durable & tear-resistant — Polyimide film provides high tensile strength and abrasion resistance for handling and repeated use.
- Clean removal — Silicone PSA engineered for minimal residue on common smooth substrates after thermal exposure. For extended high-temperature dwell time or low-surface-energy plastics, application testing is recommended.
- Matte surface advantage — Lower reflectivity reduces glare and improves visual contrast for inspection, optical alignment and masking tasks.
- Matte black finish — Reduces glare and improves visual contrast for inspection, alignment, and masking. The black surface can also help reduce stray light reflection in optical-sensitive assemblies; suitability depends on the specific design and should be validated in application.
- Flexible formats & die-cutting — Custom widths, lengths, sheets and precision die-cut parts to fit OEM production lines.
- Compliance & traceability — RoHS compliant and halogen-free where applicable; full traceability and test reports available on request.
Applications
Electronics Manufacturing & PCB Assembly
Wave-solder masking, component protection, gold-finger insulation, FPC lamination and securing components during thermal cycles. Ideal where reduced glare aids inspection of solder joints and component placement.

Heat protection during rework and component removal; protects adjacent components during hot-air or IR processes.
Motor, Transformer & Coil Insulation
Bundling and securing coils in motors, transformers and inductors, providing reliable electrical insulation under operational heat.
Aerospace & Automotive Electronics
Insulation and protection for wiring, sensors and electronics exposed to elevated temperatures and chemical environments.
High-Temperature Masking & Surface Protection
Masking for powder coating, spray painting, sandblasting and thermal curing processes; matte finish reduces reflection that can impact optical curing/inspection.
3D Printing & Thermal Fixtures
Applied to heated build plates or tooling surfaces to improve part adhesion and reduce warpage during thermal cycles.
Battery & Cable Applications
Insulation for lithium-ion battery modules, cell assembly fixtures and wire harness routing where thermal stability and electrical isolation are required.
FAQS
Q1: What is the difference between matte black Kapton tape and gloss black Kapton tape?
A: Both matte and gloss black Kapton tapes share similar chemical, thermal, and electrical properties.
The key difference lies in surface finish: matte black Kapton tape reduces glare and improves inspection visibility, while gloss black Kapton tape provides a smoother, more reflective surface.
Selection depends on visual inspection requirements, masking precision, and assembly workflow.
Q2: Can matte black Kapton tape be used in reflow soldering?
A: Yes. Matte black Kapton tape is typically rated for continuous exposure up to 260 °C and can withstand short-term temperature peaks depending on adhesive grade and reflow profile.
For best results, verify dwell time, peak temperature, and substrate compatibility under your specific soldering process.
Q3: Is matte black Kapton tape chemically resistant?
A: Matte black Kapton tape is resistant to many common industrial solvents, oils, flux residues, and cleaning agents.
Resistance to strong acids, alkalis, or highly corrosive chemicals depends on exposure time and concentration; application-specific testing is recommended.
Q4: Can I apply matte black Kapton tape on 3D printer beds?
A: Yes. Matte black Kapton tape is commonly used on heated 3D printer build plates, particularly for materials such as ABS and certain engineering filaments.
Adhesion performance depends on bed temperature, filament type, and surface preparation. Ensure the build plate is clean and does not exceed the tape’s rated thermal limits.
Q5: What thickness options are available for black Kapton tape?
A：Black Kapton tape is available in multiple thickness options depending on film gauge and adhesive coat weight.
Typical polyimide film thickness is 25 μm (1 mil), with total tape thickness commonly ranging from 50 μm to 60 μm.
Other thickness configurations can be customized to meet specific electrical, thermal, or mechanical requirements. Please contact us with your application details for tailored recommendations.
