Professional-grade black polyester film tape with aggressive acrylic adhesive for industrial splicing, web processing, and high-temperature applications. Offers quick stick, permanent hold, and excellent durability across -60°F to 300°F temperature range.
3M™ Polyester Film Tape 850 is a premium industrial-grade adhesive tape designed for demanding splicing and web processing applications. Featuring an aggressive acrylic adhesive that provides quick stick and excellent long-term holding power, this tape is engineered for applications requiring permanent bonds and reliable performance. The thin, high-strength polyester backing meets low caliper requirements, ensuring it won't interfere with most machinery processes while resisting tearing and protecting surfaces from abrasion and rough handling.
This professional-grade tape delivers exceptional performance across a wide temperature range from -60°F to 300°F (-50°C to 150°C), making it suitable for both cold and high-temperature industrial operations. The pressure-sensitive acrylic adhesive grabs on contact and holds butt splices securely, making it ideal for web processing, label protection, marking, core starting, and decorative edging applications. Available in black, transparent, and silver versions, the tape meets various aerospace specifications and provides chemical and solvent resistance in transparent formulations.
With a tensile strength of 28 lb/in and 120% elongation at break, this tape combines durability with flexibility for reliable performance in challenging industrial environments. Each case contains 72 rolls of 1/2 inch width by 72 yards length, providing ample inventory for continuous production operations. The tape is specifically formulated for industrial and occupational use, meeting ASTM D3330, ASTM D3652, and ASTM D3759 specifications.
