Professional-grade silver polyester film tape with aggressive acrylic adhesive for industrial splicing, web processing, and marking applications. Temperature resistant from -60°F to 300°F with aerospace specifications compliance.
The 3M™ Polyester Film Tape 850 in Silver is a professional-grade industrial adhesive tape specifically designed for demanding splicing and web processing applications. This high-performance tape features an aggressive acrylic pressure-sensitive adhesive that provides quick stick and excellent long-term holding power, making it ideal for applications requiring immediate and permanent bonding. The tape comes in a convenient 1/4 inch width with 72 yards of length per roll, packaged as 144 rolls per case for bulk industrial use.
Constructed with a thin, high-strength polyester backing that resists tearing and protects surfaces from abrasion and rough handling, this tape meets low-caliper requirements to ensure it won't interfere with most machinery processes. The silver color version is highly visible for applications where marking or identification is required, such as defect flagging and decorative striping. With an operating temperature range of -60°F to 300°F (-50°C to 150°C), this tape performs reliably in both extreme cold and high-temperature environments.
Meeting a variety of aerospace specifications including ASTM D3330, ASTM D3652, and ASTM D3759, the 3M Polyester Film Tape 850 is engineered for professional industrial and occupational use. It delivers tensile strength of 28 lb/in with 120% elongation at break, providing durability and flexibility for complex splicing operations. Ideal for web processing, label protection, marking, core starting, film splicing including movie film, and various decorative applications across automotive, construction, electronics, military, and transportation industries.
