3M 7000048772 Polyester Film Tape 850 Black 1.9 Mil

Product Description

The 3M 7000048772 is a black polyester film tape from the 3M 850 series, constructed with a 1.9 mil polyester film backing and a pressure-sensitive acrylic adhesive. At 1.5 inches wide and 72 yards long, each roll provides substantial coverage for industrial and trade applications. The polyester film construction delivers chemical resistance and dimensional stability under temperature cycling, making it suitable for environments where standard vinyl or paper tapes would fail. Electricians, HVAC technicians, and general maintenance professionals use this tape where a clean, conformable, and chemically resistant hold is required.

This tape is designed for splicing, masking, color coding, holding, decorating, and sealing tasks across a range of industrial and commercial settings. Its black pigmentation makes it well suited for color coding applications and situations where light blocking or aesthetic consistency is needed. The acrylic adhesive bonds reliably to metals, plastics, and smooth substrates commonly encountered in electrical panels, HVAC equipment, and light manufacturing environments. It performs in both low-humidity and high-humidity conditions without significant adhesive bleed or flagging at the edges.

Key Features

• 1.9 mil polyester film backing provides tear resistance and dimensional stability
• Acrylic adhesive offers strong, clean-removal bonding on common trade substrates
• Chemical-resistant construction withstands solvents and cleaning agents
• Black pigmentation supports color coding and light-blocking applications
• 1.5 inches wide by 72 yards long per roll for high-coverage tasks
• Suitable for splicing, sealing, holding, and decorating applications

Compatibility

Designed as a general-purpose polyester film tape for use in electrical, HVAC, plumbing, and light industrial applications where chemical resistance and conformability are required.

Installation Notes

Apply to clean, dry surfaces free of oil, dust, and moisture for best adhesion. When used in electrical applications, verify the tape rating meets applicable NEC requirements for the intended use. Remove power from any electrical equipment before applying or repositioning tape near live components. Avoid stretching the tape during application to prevent edge lifting over time.
