3M 7000047522 Polyester Film Tape 850 Silver 1.9 Mil

Product Description

The 3M 7000047522 is a silver polyester film tape in the 3M 850 series, constructed with a 1.9 mil polyester film backing and a pressure-sensitive acrylic adhesive. The tape measures 1 inch wide and comes on a 72-yard roll, making it suitable for extended runs without frequent roll changes. The acrylic adhesive system provides chemical resistance and maintains adhesion across a range of temperatures. Technicians and tradespeople use this tape for splicing, color coding, sealing, and general holding applications where a durable, dimensionally stable film tape is required. The silver finish also delivers reflective properties suited for applications where visibility or heat reflection is a factor.

This tape is used across electrical, HVAC, and industrial applications. It performs well in environments where chemical exposure or moderate temperature swings are a concern. Common uses include splicing film or foil materials, securing insulation overlaps, color coding conduit or piping runs, and sealing light-duty packaging or assemblies. It is also used in decorative and labeling applications where a clean silver appearance is needed. The roll format suits both bench work and field installation.
