3M 888519009185 Polyimide Film Tape 2in 36yd Acrylic

Product Description

The 3M 888519009185 is a polyimide film tape with an acrylic adhesive backing, designed for high-temperature masking, insulation, and protection applications in electrical and electronics work. The tape measures 2 inches wide and 36 yards (108 feet) long, with a total thickness of 3 mil. The amber-colored polyimide film construction handles continuous operating temperatures up to 311 degrees F, making it suitable for wave soldering, powder coating masking, and thermal insulation tasks where standard tapes fail. Tensile strength is rated at 30 lb per inch, providing reliable hold under mechanical stress during and after installation.

This tape is commonly used by electricians, electronics technicians, and industrial maintenance professionals. Typical applications include insulating and bundling wire harnesses, masking surfaces during high-heat manufacturing processes, and protecting components in HVAC control boards and variable-frequency drives during rework or conformal coating. The acrylic adhesive bonds firmly to metal, plastic, and circuit board surfaces without leaving residue under high-heat cycling conditions.

Key Features

• Polyimide film construction rated to 311 degrees F maximum operating temperature
• 3 mil total thickness for durable, flexible coverage
• Acrylic adhesive provides clean removal and residue-free bonding on sensitive surfaces
• 30 lb per inch tensile strength resists tearing during application and removal
• Amber color allows visual inspection of underlying components through the tape
• 36 yd (108 ft) roll length suited for production-volume or field use

Compatibility

Designed as a general-purpose high-temperature masking and insulation tape for use in electrical, electronics, and HVAC applications where polyimide film construction and acrylic adhesive performance are required.

Installation Notes

Installation does not require power disconnection in most masking applications, but always de-energize electrical panels or control boards before applying tape near live components. Ensure surfaces are clean, dry, and free of oils or contaminants before application for optimal adhesion. Use a squeegee or roller to eliminate air bubbles when applying to flat surfaces. Cutting should be done with a sharp blade or scissors rated for film tapes to avoid tearing or ragged edges.
