Exceptionally Tough Tape with Burn Resistance
In order to meet tough aerospace and regulatory requirements, we make 3M™ Polyurethane Protective Tape 8657 from an exceptionally tough, thermoplastic polyurethane elastomer that resists puncture, tearing and abrasion. Our tape is uniquely formulated to pass the burn resistance requirements of FAR 25.853* when tested alone or as a covering applied to floor panels.
When applied over aircraft floor panels, 8657 creates an ideal barrier against most fluids and helps prevent liquids from causing corrosion to the floor system. 8657 incorporates a specially formulated pressure sensitive adhesive for fast and easy application. Using 3M™ Polyurethane Protective Tape 8657 on floor panels can help reduce corrosion and costly replacement of stringer beams - and keep your aircraft flying. This product is supplied with a 3 mil polyethylene liner to protect the adhesive and aid with fast, easy installation. The liner also helps preserve the tape during storage and handling prior to use.
