Premium black polyester film tape with aggressive acrylic adhesive for industrial splicing, web processing, and marking. 1.5 in x 72 yd per roll, 24 rolls per case. Temperature range -60°F to 300°F. Meets ASTM specifications.
3M™ Polyester Film Tape 850 in Black is a premium industrial-grade adhesive tape designed for demanding splicing and web processing applications. This high-performance tape features a thin, high-strength polyester film backing combined with an aggressive acrylic adhesive that provides quick stick and excellent long-term holding power. The tape measures 1.5 inches wide by 72 yards long with a 1.9 mil thickness, packaged in convenient cases of 24 rolls. The pressure-sensitive acrylic adhesive grabs on contact to hold 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, ensuring reliable performance in high-speed machinery environments. With a wide operating temperature range from -60°F to 300°F (-50°C to 150°C), this tape maintains its adhesive properties across diverse industrial settings. The thin profile meets low-caliper requirements, ensuring it won't interfere with most machinery processes or create unwanted buildup. Each roll delivers consistent performance with 120% elongation at break and tensile strength of 28 lb/in, providing the durability needed for challenging industrial applications.
This product is specifically formulated for industrial and occupational use only and is not intended for consumer applications. It meets ASTM D3330, D3652, and D3759 specifications, making it suitable for aerospace, automotive, electronics, food and beverage, packaging, and other demanding industries. The black color provides excellent visibility for defect marking and identification purposes, while the chemical and solvent-resistant transparent version is available for specialized applications requiring readability and protection.
