In industrial manufacturing, electronics assembly, and powder coating processes, high temperature tape is an indispensable material. Whether it's Kapton tape widely used in PCB masking, or LZM (Lv Zhi Mei) tape, known for its affordability and performance, users often encounter problems such as adhesive failure, edge lifting, residue, or poor bonding.
In this article, we’ll break down 8 common high temperature tape issues, their causes, and practical solutions, using examples from both Kapton and LZM tape.

1. Adhesive Failure: Tape falls off quickly after application?
Possible Causes:
• Surface contamination: dust, oil, or moisture
• Incompatible surface materials (e.g., low surface energy plastics)
• Tape aging due to improper storage
Solutions:
• Clean surface thoroughly with isopropyl alcohol
• Choose the right adhesive chemistry (LZM uses high-performance silicone, ideal for metal/plastic)
• Store tape in a cool, dry place, away from direct sunlight

2. Edge Lifting: Tape peels at the corners or edges over time?
Possible Causes:
• Uneven pressure during application
• Low initial tack
• Poor adhesion on curved or irregular surfaces
Solutions:
• Use a roller to apply uniform pressure
• Kapton tape offers excellent initial tack and adhesion to complex curves
• For narrow or curved masking, LZM’s flexible PET-based tape performs better

3. Poor Bonding: Tape just doesn’t stick well?
Possible Causes:
• Low-tack adhesive type mismatched with application
• Cold application surface reducing adhesion performance
Solutions:
• Select appropriate adhesive strength (LZM high-tack PET tape for powder coating)
• Warm up the tape or surface before application (Kapton tape activates optimally at 180–260°C)

4. Residue After Removal: Tape leaves sticky marks?
Possible Causes:
• Incompatible adhesives
• Adhesive breakdown under high heat
Solutions:
• Use anti-residue tapes, such as LZM’s no-residue series
• Kapton tape uses imported silicone adhesive, leaving virtually no residue even after 260°C heat exposure

5. Tape Breakage or Distortion During Use
Possible Causes:
• Weak tensile strength of base material
• Incorrect handling or stretching
Solutions:
• Choose materials like fiberglass or PI (polyimide) for high tensile strength (e.g., Kapton tape)
• Apply tape gently, avoid overstretching

6. Temperature Mismatch: Tape fails under high heat?
Possible Causes:
• Tape rating lower than actual operating temperature
Solutions:
• Match the tape to the temperature range
• LZM PET tape: up to 150°C
• Kapton PI tape: up to 260–350°C for reflow soldering, baking, etc.

7. Difficult to Cut or Tear Manually
Possible Causes:
• Tape thickness or excessive stickiness
• Lack of proper cutting tools
Solutions:
• Use tape dispensers or hot knives
• LZM tapes with release liners are easier to handle and cut

8. Deformed Tape Cores Causing Machine Issues
Possible Causes:
• Humid storage or compression damage
• Poor-quality paper or plastic cores
Solutions:
• Store tapes in a dry, ventilated area without heavy stacking
• Kapton and LZM both offer custom plastic or reinforced cores for automatic machines

Final Advice: The Right Tape + Proper Use = Maximum Efficiency
Whether you prefer the high-performance Kapton high temperature tape or the cost-effective LZM tape, most issues can be avoided by understanding the application environment and choosing the right product.
