3M - 3939 Tape - Duct - Heavy Duty - Silver - 48mm x 55m

Features

• 3M™ heavy duty duct tape 3939 is constructed of a water resistant polyethylene laminated to cloth reinforcement and backed by an aggressive natural rubber adhesive; the tape is high tack and conformable
• Our tape tears easily and cleanly-horizontally or vertically-without slivering
• Industrial applications include hanging polyethylene drapes for containment activities, masking and sandblast overspray protection
• It is also used in the convention industry for holding and seaming carpet padding, taping down cords and hinging poster board panels
• 3M™ heavy duty duct tape 3939 can be used in temperatures up to 200 degrees F
• It has been burn tested according to the methods UL 723, ASTM E 84, NFPA 255, UBC 8 1
• Results were Flame Spread Index 0, Smoke Developed Index 30
• Duct tape (sometimes mistakenly referred to as "duck tape") is a toolbox mainstay, used in maintenance, repair and construction operations
• The term "duct tape" comes from the silver tape’s original use in heating, ventilation and air conditioning (HVAC) applications, including duct sealing
• Today it performs wherever patching, bundling, reinforcing, tabbing, splicing insulation, capping pipe and conduit ends, labeling, temporary repair, hanging polyethylene drapes, or protecting against light sandblast overspray is needed
• Duct tape is used in residential, industrial and commercial environments and by members of construction, electrical, industrial, marine, and military, abatement, trucking and automotive markets
• Industrial-grade duct tape for splicing, masking, patching, sealing and seaming
• High tensile strength for a secure hold under stress
• Thick rubber adhesive bonds to most rough and smooth surfaces for a tight seal
• Silver polyethylene surface resists wear, abrasion and water
• 3M™ heavy duty Duct tape 3939 has the tensile strength and adhesion for splicing, masking, patching, seaming, hanging poly sheeting, sealing PVC pipes, covering trip hazards and a host of other industrial applications
