Premium transparent polyester film tape with aggressive acrylic adhesive for industrial splicing, web processing, and aerospace applications. Offers quick stick, excellent holding power, and superior temperature resistance from -60°F to 300°F.
3M™ Polyester Film Tape 850 is a premium industrial adhesive tape designed for demanding splicing and web processing applications. This transparent polyester film tape features an aggressive acrylic adhesive that provides quick stick and excellent long-term holding power, making it ideal for butt splice applications where permanent bonds are required. The tape measures 3.5 inches in width with a total length of 72 yards per roll, and comes in a convenient 12 roll case format for industrial users.
The thin, high-strength polyester backing is engineered to meet low caliper requirements, ensuring it won't interfere with most machinery processes while providing exceptional abrasion resistance and protection against rough handling during web processing. With a total tape thickness of only 1.9 mil (0.05mm), this tape is specifically designed for applications requiring minimal profile impact. The transparent formulation is chemically and solvent resistant, making it suitable for various industrial environments including aerospace, automotive, electronics, and general manufacturing sectors.
Operating across an impressive temperature range from -60°F (-50°C) to 300°F (150°C), the 3M Polyester Film Tape 850 maintains its performance integrity in both extreme cold and high-temperature applications. The tape meets rigorous industry standards including ASTM D3330, ASTM D3652, and ASTM D3759, ensuring reliability and consistency for critical industrial operations. Recommended applications include core starting, splicing, web defect marking, sealing, label protection, and aerospace applications where specification compliance is mandatory.
