Product Description
Kapton Tape (Acrylic Adhesive) is a high-performance thermal insulation tape meticulously designed to meet the rigorous demands of various industries. This advanced tape features a durable polyimide film base coated with a premium acrylic adhesive, making it ideal for applications that require reliable thermal protection.
Rated for continuous use up to 155 °C (Class F), this tape is suitable for electrical insulation, wire harnessing, motor/transformer wrapping, lithium battery assembly, and moderate-temperature masking. For reflow/wave soldering or high-temperature powder-coating cure profiles, please use silicone-adhesive polyimide tape and validate under your process conditions.
The acrylic adhesive offers strong bond strength and is designed for clean removal with minimal residue on common smooth substrates when removed within the recommended temperature/time window.
Compared with silicone PSA options, acrylic adhesive constructions can offer strong initial tack and good shear strength for moderate-temperature applications, providing a cost-effective solution for Class F electrical insulation projects.

FAQs
Q1: What is the maximum operating temperature for acrylic adhesive Kapton tape?
Acrylic adhesive Kapton tape is typically rated for continuous use up to 155 °C (grade-dependent). Performance depends on dwell time, thermal profile, and substrate type, so application testing is recommended for critical or long-duration heat exposure.
Q2: What is the difference between acrylic Kapton tape and silicone Kapton tape?
The primary differences are temperature capability and adhesive behavior. Silicone-adhesive polyimide tapes are commonly selected for higher-temperature processes (often up to ~260 °C, grade-dependent) such as reflow/wave masking. Acrylic-adhesive polyimide tapes are typically used for moderate-temperature applications (often up to ~155 °C) and may offer strong initial tack and a cost-effective option depending on the construction. Selection should be based on your temperature profile, dwell time, and substrate requirements
Q3: Will acrylic Kapton tape leave adhesive residue after heat exposure?
Acrylic adhesive polyimide tapes are designed for clean removal with minimal residue on smooth, clean substrates when removed within the recommended temperature/time window. Residue performance depends on substrate type, surface cleanliness, temperature, and dwell time; sample trials are recommended for critical surfaces.
Q4: What industries commonly use acrylic Kapton tape?
Acrylic adhesive polyimide tape is commonly used for Class F electrical insulation, wire harnessing, motor/transformer wrapping, electronics assembly, and general industrial masking where moderate heat resistance and stable bonding are required. For battery or high-temperature processes, select the adhesive system based on the actual temperature profile and chemical exposure.
Q5: Can acrylic Kapton tape be customized for OEM or automated production?
Yes. Acrylic polyimide tape can be supplied in custom slit rolls, sheets, and die-cut parts. Options such as release liner type, winding direction, and core size are available depending on converting requirements. MOQ and lead time depend on the requested format and specification.
