About 3M TALC Metallized Flexible Duct Tape
Product Description 3M Metallized Flexible Duct Tape 3350 is a 3.1 mil thick silver polypropylene tape with an aggressive acrylic adhesive used for sealing flexible ducts and connector systems. This tape meets the requirements of UL181B-FX and is used by commercial contractors in the residential and commercial construction industry. From the Manufacturer 3M™ Metalized Flexible Duct Tape 3350 Silver, with its aggressive adhesive and durable backing, is ideal for closure and repair of flexible ducts and air connectors and securing flex duct-to-duct wrap facings and metal-to-metal connections. This tough, versatile tape seals and secures seams and joints for long-term durability in HVAC, appliance automotive, construction, general industrial, metalworking, MRO, transportation, and more. Its bi-axially oriented polypropylene (BOPP) backing provides improved strength and flexibility over oriented polypropylene (OPP) tapes, and the acrylic adhesive combines to give the tape the lasting endurance for a variety of applications including HVAC flexible duct work. The acrylic adhesive maintains a strong bond through a range of temperatures to provide long-term endurance. Thermally conductivity helps dissipate excess heat and keep the tape in place. This durable tape resists flame, moisture, weather, UV degradation, is chemical resistant, and carries a UL 181 B-FX Listing for Class 1 flexible duct sealing as well as UL 723 listing for duct sealing and general repairs. How to Choose the Right Duct Tape One of the most important points to think about when choosing a duct tape is how it is going to be used. When it comes to choosing a 3M™ Duct Tape that meets the need for a particular job, consider the following: Performance Plus and Outdoor Masking Tapes are best in class tapes for indoor/outdoor use, offering clean removal and long term weatherability. Extra Heavy Duty, Heavy Duty, and Multi Purpose duct tapes provide reliable performance for demanding contractor, MRO and industrial job site applications. And General Purpose duct tapes offer cost-effective options for general and lighter duty applications such as bundling, sealing, holding, and identifying. Strength, moisture resistance, abrasion resistance, heat resistance, and clean removal impact the effectiveness of any duct tape. Two of three key factors that determine these factors are backing and adhesive. The thicker the backing, the greater tensile strength (the resistance to breaking under tension), moisture, and abrasion resistance provided. A rubber-based or synthetic rubber adhesive provides instant stick, a strong bond, and long-lasting hold, even in moist conditions. Lastly, the distinctive cloth scrim, laminated between the backing and the adhesive, adds additional strength and also helps guide straight, horizontal and vertical tearing. One last and often overlooked fact about tapes in general, is that they all need to be stored correctly and they all have a shelf life. Weak adhesion, lifting, curling, and breakage are more often than not, attributable to age or improperly stored tape, as opposed to quality. In all cases, care should be taken to read all product information thoroughly. In particular, the tape's specifications should be weighed against the task at hand to ensure successful, cost-effective outcomes.
