Premium 43 mil polyurethane protective tape with foam acrylic adhesive for aerospace impact protection, abrasion resistance, and FOD prevention on pressurized and non-pressurized surfaces.
3M™ Polyurethane Protective Tape 8642 is a premium high-impact protective tape specifically engineered for aerospace and industrial applications. This 43 mil thick urethane-based tape delivers exceptional impact resistance, particularly against small foreign object damage (FOD), making it ideal for protecting critical aircraft surfaces and components. The tape features an extremely tough elastomer construction combined with a foam acrylic adhesive that adheres reliably to a wide variety of substrates, ensuring superior performance in demanding environments.
The perforated design of this protective tape allows for flexible application on both pressurized and non-pressurized surfaces, providing versatility for diverse aerospace maintenance and protection needs. The tape's exceptional abrasion, erosion, scratch, and puncture resistance ensures long-term durability, significantly reducing aircraft downtime and maintenance costs. With a maximum operating temperature of 82°C (180°F) and minimum operating temperature of -40°C (-40°F), this tape maintains its protective properties across extreme temperature ranges commonly encountered in aerospace operations.
Designed to meet rigorous aerospace industry standards, the 3M Polyurethane Protective Tape 8642 is part of 3M's comprehensive solution portfolio for aircraft protection. Each case contains one roll of this high-performance tape, backed by 3M's commitment to quality and innovation in aerospace protection solutions. The foam acrylic adhesive provides strong adhesion strength of 46.8 lb (819 N/100mm), ensuring reliable surface protection throughout the service life of the aircraft.
