The INTERTAPE 20C-Y 2 is a yellow polyethylene foam duct tape engineered for demanding sealing, bundling, and closure applications in construction and mechanical trades. At 9 mil thick with an 18 lb/in tensile strength and a rubber adhesive backing, this tape delivers a firm, reliable bond on a variety of substrates. It handles temperatures from 32 degrees F to 160 degrees F, making it suitable for both ambient interior work and moderate-heat environments. Installers working with HVAC duct systems, vapor barriers, and building envelope assemblies will find this tape a practical, code-recognized option for seaming and sealing tasks.
The AC20 series tape is commonly used in residential and light commercial construction for box closing, bundling, sealing, seaming, and wrapping. Its yellow color aids visibility during inspection. The tape meets BOCA Code, HUD Code, L.A. County Code, and UL 723 standards, positioning it as a compliant choice for projects where code-recognized materials are specified. Trades including HVAC technicians, insulation contractors, and general construction crews regularly use this product during rough-in and finish work.
Designed for general-purpose sealing and bundling applications in construction and mechanical trade environments where polyethylene foam duct tape meeting recognized code standards is required.
This tape is applied by hand or with a standard tape gun; no special tools are required. Surfaces should be clean, dry, and free of dust or oil before application to ensure full adhesive contact. For HVAC or building envelope applications, verify that local code requirements are satisfied by the applicable listed standards before installation. Store unused rolls away from direct sunlight and extreme temperatures to preserve adhesive performance.
