Premium polyester film tape with aggressive acrylic adhesive for industrial splicing, web processing, and marking applications with superior temperature resistance and durability.
3M™ Polyester Film Tape 850 is a premium industrial adhesive tape specifically designed for splicing applications requiring quick stick and aggressive, permanent hold capabilities. This high-performance tape features a thin, high-strength polyester backing that meets low caliper requirements, ensuring it won't interfere with most machinery processes. The tape is coated with an aggressive pressure-sensitive acrylic adhesive that grabs on contact and holds butt splices securely, making it ideal for web processing, label protection, and marking applications.
The polyester backing is engineered to resist tearing and protect surfaces from abrasion and rough handling, significantly reducing splice failures during web processing. With exceptional durability, this tape can withstand a wide temperature range from -60°F/-50°C to 300°F/150°C, making it suitable for both low and high-temperature operations. The tape offers 120% elongation at break and delivers tensile strength of 28 lb/in, providing reliable performance in demanding industrial environments.
Available in multiple colors including red, black, white, and transparent versions, 3M Polyester Film Tape 850 meets various aerospace specifications and industry standards including ASTM D3330, ASTM D3652, and ASTM D3759. The red color variant is highly visible for applications where marking or identification is required, while the transparent version provides chemical and solvent resistance for protective applications. Each case contains 8 rolls, with each roll measuring 4 inches wide by 72 yards long at 1.9 mil thickness, providing ample supply for continuous industrial operations.
