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, meets aerospace specifications.
The 3M™ Polyester Film Tape 850 in Silver is a premium industrial adhesive tape specifically engineered for 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 demanding industrial environments. The thin, high-strength polyester backing is designed to meet low caliper requirements, ensuring it won't interfere with most machinery processes while providing superior abrasion resistance and protection against rough handling during web processing operations.
This professional-grade tape is engineered to withstand extreme temperature ranges from -60°F (-50°C) to 300°F (150°C), making it suitable for both cold and high-temperature industrial operations. The silver color provides high visibility for applications requiring marking, identification, or defect flagging where reflective sensing is necessary. The polyester backing resists tearing and protects surfaces from abrasion and rough handling, significantly reducing splice failures and breakdowns during critical web processing operations. With its low modulus and low Shore A Hardness properties, this tape delivers consistent performance across diverse industrial applications.
Meeting multiple aerospace specifications and ASTM standards (ASTM D3330, ASTM D3652, ASTM D3759), the 3M Polyester Film Tape 850 is suitable for use in appliance manufacturing, automotive, construction, electronics, military and government applications, print processing, specialty vehicles, and transportation industries. Each roll measures 48 inches in width and 72 yards in length with a total tape thickness of 1.9 mil, providing ample coverage for large-scale industrial splicing and marking applications.
