3M 888519017395 Polyimide Film Tape 0.5 in 3 Mil 311F

Product Description

The 3M 888519017395 is a polyimide film tape designed for high-temperature masking, insulation, and protection applications in electrical and electronics work. This amber tape measures 0.5 inches wide by 15 feet long and carries a 3 mil thickness, making it a low-profile solution for precise masking over tight components. The acrylic adhesive provides reliable bonding and clean removal, and the polyimide film backing withstands continuous exposure up to 311 degrees F. Electricians, electronics technicians, and industrial maintenance pros use this tape where standard polymer tapes would fail under heat.

This tape is suited for circuit board masking during wave soldering, coil wrapping, transformer insulation, and similar high-heat electrical assembly or repair tasks. The 0.5 inch width allows accurate placement over narrow traces, terminals, or component leads without overlap onto adjacent areas. It performs in both production-line and field-service settings where thermal resistance and dimensional stability under heat are required.

Key Features

• Polyimide film backing maintains dimensional stability at elevated temperatures up to 311 degrees F
• Acrylic adhesive bonds cleanly and removes without heavy residue
• 3 mil total thickness keeps the tape profile low for tight component clearances
• 30 lb per inch tensile strength resists tearing during application and removal
• Amber color allows visual confirmation of tape placement over components
• 0.5 inch width suits narrow masking on PCBs, terminals, and coil windings

Compatibility

Designed as an OEM-style polyimide masking tape for high-temperature electrical insulation and surface protection applications where a 0.5 inch wide, 3 mil tape with acrylic adhesive is specified.

Installation Notes

Application is typically performed by electricians or electronics technicians. Ensure the target surface is clean, dry, and free of oils or flux residue before applying the tape. Power down and de-energize any electrical assembly before applying or removing tape near live components. Avoid stretching the tape during application to maintain consistent thickness and adhesive contact.
