Professional-grade silver polyester film tape with aggressive acrylic adhesive for industrial splicing, web processing, and marking applications. Temperature resistant from -60°F to 300°F with superior tear resistance and aerospace compliance.
The 3M™ Polyester Film Tape 850 in Silver is a premium industrial adhesive tape specifically designed for splicing and web processing applications. This high-performance tape features an aggressive acrylic adhesive that provides quick stick and excellent long-term holding capability, making it ideal for demanding industrial environments. The backing is constructed from thin, high-strength polyester film that meets low caliper requirements, ensuring it won't interfere with most machinery processes while maintaining superior abrasion resistance.
This specialized tape is engineered to withstand extreme temperature ranges from -60°F (-50°C) to 300°F (150°C), making it suitable for high-temperature operations and diverse industrial applications. The polyester backing resists tearing and protects surfaces from abrasion and rough handling, significantly reducing splice failures during web processing. With an elongation at break of 120% and tensile strength of 28 lb/in, this tape delivers exceptional durability and reliability.
The silver version is highly visible for applications requiring marking or identification, and it meets a variety of aerospace specifications including ASTM D3330, ASTM D3652, and ASTM D3759. Each case contains 36 rolls, making it an economical choice for high-volume industrial operations. Whether used for defect flagging, decorative striping, or splicing of film including movie film, this tape provides consistent performance and professional-grade results in demanding industrial settings.
