Industrial-grade transparent polyester film tape with aggressive acrylic adhesive for splicing, web processing, and label protection. Temperature range -60°F to 300°F, meets aerospace specifications.
3M™ Polyester Film Tape 850 is a premium industrial adhesive tape engineered for demanding splicing and web processing applications. Featuring an aggressive acrylic pressure-sensitive adhesive that grabs on contact and provides excellent long-term holding power, this tape is designed for applications requiring quick stick and permanent bonds. The thin, high-strength polyester backing measures 1.9 mil thickness and meets low-caliper requirements to ensure it won't interfere with most machinery processes, making it ideal for web processing, label protection, and marking applications.
The transparent polyester backing is specifically formulated to resist tearing and protect surfaces from abrasion and rough handling during web processing operations. With an impressive temperature range from -60°F (-50°C) to 300°F (150°C), this tape maintains its performance across diverse industrial environments. The transparent version is chemical and solvent resistant, making it suitable for sealing and protecting against chemical intrusion. Each case contains 12 rolls, with each roll measuring 3 inches wide by 72 yards long, providing substantial coverage for continuous production operations.
This industrial-grade tape meets rigorous aerospace specifications and ASTM standards including ASTM D3330, ASTM D3652, and ASTM D3759. The product is available in multiple colors including transparent, silver, and colored options for various marking and identification needs. With a tensile strength of 28 lb/in and 120% elongation at break, this tape delivers reliable performance in splicing butt joints, core starting, and various industrial applications across automotive, construction, electronics, food and beverage, metalworking, packaging, and transportation industries.
