Specially formulated for outstanding electrical resistance and mechanical strength, the tape features a dielectric strength over 6500 V and impressive elongation at break of 45%. Its density of 1.42 g/cm and low thermal conductivity ensure reliable performance in high-voltage and heat-sensitive environments.

Versatile Applications Across Industries

Kapton Polyimide Tapes pressure-sensitive silicone adhesive enables excellent adherence to varied surfaces. Commonly used for PCB masking during soldering, capacitor wrapping, lithium battery manufacturing, and as a bed surface in 3D printing, it suits numerous advanced industrial uses, from prototyping to large-scale electronics production.

FAQs of Kapton Polyimide Tape:

Q: How should Kapton Polyimide Tape be applied for optimal performance?

A: Ensure the surface is clean and dry. Unwind the roll, position the tape on the desired area, and press it firmly using moderate pressure to activate the pressure-sensitive silicone adhesive. This guarantees strong adhesion and effective insulation.

Q: What benefits does the high dielectric strength offer in electronic applications?

A: With a dielectric strength greater than 6500 V, Kapton Polyimide Tape provides robust electrical insulation, protecting sensitive electronic components from voltage breakdown or shorts, especially during PCB fabrication and wave soldering processes.

Q: When and where is Kapton Polyimide Tape most commonly used?

A: The tape is frequently used in industries requiring thermal and electrical insulation, such as electronics manufacturing, 3D printing, lithium battery assembly, and capacitor fabrication. Its temperature tolerance and flame retardancy make it suitable for both standard and harsh environments.

Q: What process is used for producing the adhesive side of the tape?

A: The tape utilizes a pressure-sensitive adhesive (PSA) process, where a silicone-based adhesive is evenly coated onto one side of the polyimide film, creating a durable, single-sided adhesive suitable for high-temperature and high-stress environments.

Q: How does the tapes flame retardant feature benefit industrial safety?

A: Kapton Polyimide Tape is rated UL-94 V-0 for flame retardancy, meaning it stops burning within 10 seconds on a vertical specimen. This significantly reduces fire hazards, making it a safer option in electrical and electronic assemblies.

Q: What storage conditions are ideal for maintaining tape quality?

A: To preserve adhesive and material integrity, store the tape in a cool, dry place, away from direct sunlight and sources of moisture. Proper storage ensures long shelf life and consistent performance when used.

Q: Can Kapton Polyimide Tape be used for masking during wave soldering?

A: Yes, its excellent chemical stability, thermal resistance, and electrical insulation make it particularly effective as a protective mask for PCBs during wave soldering, preventing solder from contacting covered areas.
