Need to patch a leak? Duct tape. Seal a box? Duct tape. Tie back electrical cords? Duct tape. Need to mark a danger zone? You guessed it – bright yellow duct tape. For decades, duct tape has been the quick, reliable, and inexpensive answer to a variety of situations on job sites and in homes. It’s waterproof and can hold just about anything together. But what makes this simple tool so strong and effective?

The make-up of duct tape basically comes down to three major components:

  1. Strong rubber adhesive
  2. Strong cotton fabric
  3. Strong backing

The adhesive is created from rubber (extracted from rubber trees) that is mixed with various sticky resins at a temperature higher than 200 degrees Fahrenheit. That sticky combo is then added to the cloth and the backing. Incorporating cloth is what reinforces duct tape’s incredible strength and resistance. It makes it possible for the tape to withstand heavy pulling and tearing.

3M™ Heavy Duty Duct Tape 3939, for example, has a tensile strength of 27 lbs., 432 oz/in. Lastly, the backing is made from polyurethane, which is known for exceptional tear-resistance and load-bearing capacity. BlackHawk Industrial, a trusted partner with 3M, offers more than 40,000 3M products at BHID.com.

One of Blackhawk’s popular products is the 3M™ Heavy Duty Duct Tape 3939 mentioned above, which is constructed of polyethylene film laminated to cloth with a rubber adhesive. This durable tape resists curling and tears off the roll cleanly for easy application in MRO and construction. It can be used for permanent and temporary applications.
