Industrial-grade black polyester film tape with aggressive acrylic adhesive for splicing and web processing. Temperature resistant from -60°F to 300°F. 1 inch x 72 yards per roll, 36 rolls per case.
The 3M™ Polyester Film Tape 850 in Black is a premium industrial-grade 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 butt splice applications that require permanent, secure bonds. The thin, high-strength polyester backing resists tearing and protects surfaces from abrasion and rough handling during machinery processes, while meeting low caliper requirements to ensure it won't interfere with most equipment operations.
With a temperature resistance range from -60°F/-50°C to 300°F/150°C, this tape delivers reliable performance across a wide spectrum of industrial environments. The polyester backing combines durability with flexibility, allowing it to conform to irregular surfaces while maintaining consistent adhesive performance. Available in a convenient 36 roll per case packaging format, each roll measures 1 inch wide by 72 yards long with a 1.9 mil thickness, making it ideal for high-volume industrial operations.
This tape meets multiple ASTM specifications including ASTM D3330, ASTM D3652, and ASTM D3759, ensuring compliance with industry standards for aerospace, automotive, electronics, and general industrial applications. The transparent and silver versions provide additional options for specialized applications requiring visibility or reflective sensing capabilities. Perfect for core starting, splicing and web defect marking, sealing, labeling, and protecting surfaces in demanding industrial environments.
