3M(TM) Polyester Tape 8905 Blue Plastic Core, 1 in x 72 yd
3M™Polyester Tape 8905 is a clean removing, high-temperature polyester tape. It features a tough, non-slivering, transparent blue, 5.0 mil polyester backing with silicone adhesive. These features contribute to an extremely high tensile strength while also providing the ability to perform at high temperatures.
  • Excellent thermal, abrasion and chemical resistance while maintaining flexibility
  • Silicone adhesive offers high heat resistance compared to many rubber and acrylic adhesives, reducing failure due to softening or oozing of adhesive transfer
  • Adheres well to tough-to-stick surfaces like silicone liners and fixtures coated with mold release
  • Removes cleanly from a variety of surfaces even after a 400°F/204°C bake cycle

A Polyester Backing that Endures
Our 3M™ Polyester Tape 8905 is a popular choice for a variety of difficult applications requiring high temperature resistance or adhesion to silicone treated surfaces. This tape possesses excellent thermal, abrasion and chemical resistance while maintaining flexibility. A high strength, non-slivering polyester backing offers extremely high tensile strength and high tear resistance, so it can endure rugged working conditions, including pulling through flashing or multiple paint layers.

Recommended Applications

  • Splicing of silicone treated webs
  • Masking parts for powder coat painting
  • Holding parts or sealing vacuum bags during processing
  • Masking edges of overlap seams in metal bonding process where excess adhesive can overflow
  • Composite bonding
  • Flasher breaker tape for parts from molds
  • Barrier for separation of dissimilar materials
  • Holding silicone or silicone treated parts

Clean Application and Removal with Silicone
This tape features a pressure sensitive silicone adhesive that is ideal for high temperatures to allow it to perform within a wide temperature range (-60°F/-50°C to 400°F/204°C). This high heat resistance helps prevent failure from softening or oozing. The adhesive is long-aging to allow this tape to remain adhered and flexible. Silicone adhesives stick well to difficult surfaces such as silicone liners and silicone coated surfaces. It also works well in composite bonding applications as it sticks well to molds treated with a release agent, works as a flasher breaker tape on removal of part from mold and seals vacuum bags if vacuum bag treatment is part of the process. When finished this tape removes cleanly and easily to eliminate time consuming cleaning processes. This tape will remove cleanly from a variety of surfaces even after a 400°F/204°C bake cycle.
