Long Description
Avery Dennison™ FASSON® 0950 Black is a 10-mil industrial-grade cloth tape engineered specifically for sealing joints and seams in HVAC systems, where durability, strong adhesion, and reinforcement are required. It is manufactured in the USA and tested in accordance with UL 723, meeting flame and smoke standards often necessary in building construction and HVAC ducting applications.
This product features a scrim-reinforced facestock that delivers excellent tensile strength and resistance to tearing in all directions (tri-directional reinforcement), while the rubber-based adhesive ensures a strong bond to a wide variety of surfaces, including metal, duct board, and insulation materials. Available in both black and silver, the tape supports aesthetic preferences and visibility in application environments.
Key Features
Tri-directional scrim-reinforced facestock enhances durability and tear resistance
Rubber-based adhesive offers excellent tack and long-term bond strength
Good quick stick performance ensures immediate adhesion on contact
Available in black and silver for enhanced visual appeal or contrast
Tested to UL 723, meeting fire safety standards for HVAC systems
Made in the USA, ensuring quality and reliable supply
Typical Applications
Sealing seams and joints in HVAC ductwork
Reinforcing insulation facings (foil, scrim, kraft)
General industrial sealing where strong adhesion and durability are needed
Bundling and patching in construction or mechanical systems
Applications requiring a high-performance cloth tape with strong mechanical integrity
