Professional-grade silver polyester film tape with aggressive acrylic adhesive for industrial splicing applications. Quick-stick formula with excellent long-term holding power, temperature resistant from -60°F to 300°F, meets aerospace specifications.
The 3M™ Polyester Film Tape 850 in Silver is a premium industrial adhesive tape specifically engineered for demanding splicing and web processing applications. This high-performance tape features an aggressive acrylic adhesive that provides quick stick and excellent long-term holding power, making it ideal for applications requiring permanent bonds. The thin, high-strength polyester backing combines durability with low caliper design, ensuring it won't interfere with most machinery processes while providing superior resistance to tearing and abrasion during rough handling.
Designed for industrial and occupational use, this tape excels in butt splicing, core starting, and general industrial applications. The silver version offers high visibility for applications where marking or identification is critical, including defect flagging where reflective sensing is required and decorative striping applications. With an operating temperature range from -60°F to 300°F (-50°C to 150°C), this tape maintains its performance characteristics across extreme conditions. The polyester backing resists tearing and protects surfaces from abrasion and rough handling, making it suitable for web processing, label protection, and marking applications.
This professional-grade tape meets a variety of aerospace specifications and industry standards including ASTM D3330, ASTM D3652, and ASTM D3759. Each case contains 24 rolls, with each roll measuring 1.5 inches wide by 72 yards long and 1.9 mil thickness, providing substantial coverage for industrial operations. The low modulus and low Shore A Hardness characteristics ensure optimal flexibility and conformability to various substrates.
