Industrial-grade polyester film tape with aggressive acrylic adhesive for splicing, web processing, and marking applications with temperature resistance from -60°F to 300°F
3M™ Polyester Film Tape 850 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 splices and web defect marking. The thin, high-strength polyester backing delivers exceptional durability while meeting low caliper requirements to ensure compatibility with most machinery processes without interference.
The tape's polyester backing resists tearing and protects surfaces from abrasion and rough handling during web processing operations. With temperature resistance capabilities ranging from -60°F (-50°C) to 300°F (150°C), this tape performs reliably in both extreme cold and high-temperature industrial environments. The pressure-sensitive acrylic adhesive grabs on contact and holds butt splices securely, providing dependable performance in core starting, splicing, sealing, labeling, and decorative edging applications.
Available in multiple colors including black, transparent, and silver versions, 3M Polyester Film Tape 850 meets various aerospace specifications and industry standards including ASTM D3330, ASTM D3652, and ASTM D3759. Each case contains 18 rolls with 360 yards of tape per roll on a plastic core, providing substantial coverage for high-volume industrial operations. This product is formulated for industrial and occupational use only and must be used in compliance with applicable safety regulations and standards.
