Premium silver polyester film tape with aggressive acrylic adhesive for industrial splicing, web processing, and aerospace applications. Temperature resistant -60°F to 300°F with low profile design.
The 3M™ Polyester Film Tape 850 in Silver is a premium industrial-grade adhesive tape specifically engineered for demanding splicing and web processing applications. This tape features an aggressive acrylic pressure-sensitive adhesive that provides quick stick and excellent long-term holding power, making it ideal for butt splicing, core starting, and general industrial applications. The thin, high-strength polyester backing is designed to meet low caliper requirements, ensuring it won't interfere with most machinery processes while maintaining exceptional durability against tearing and abrasion during rough handling and web processing.
With a working temperature range from -60°F (-50°C) to 300°F (150°C), this tape delivers reliable performance across diverse industrial environments. The silver color version offers high visibility for applications requiring marking or identification, making it particularly valuable for defect flagging where reflective sensing is required, decorative striping, and aerospace applications. The tape's low modulus and low Shore A Hardness characteristics provide optimal flexibility and conformability to various substrates and surfaces.
Meeting multiple aerospace specifications including ASTM D3330, ASTM D3652, and ASTM D3759, this 3M Polyester Film Tape 850 is supplied in cases of 72 rolls, each measuring 1/2 inch wide by 72 yards long with a thickness of 1.9 mil. It is engineered exclusively for industrial and occupational use by trained professionals in manufacturing, automotive, construction, electronics, and transportation industries, delivering consistent performance for critical splicing, sealing, labeling, and protection applications.
