Duct tape is a versatile tool, but not all types are made alike.
Everyone knows about duct tape. This sticky, versatile tape works well in an astonishing number of circumstances, everything from DIY projects and household repairs to quick fixes, on-the-job repairs or even heavy-duty projects. So, what is the strongest type of duct tape?
Factors to look for
Depending on the job, you may have different needs when it comes to strength. Here’s a few factors to keep in mind:
- Tensile strength – The overall strength the tape can withstand before breaking.
- Adhesive strength – The strength the tape has in sticking to materials.
- Durability – How long the tape will last.
For some jobs, tensile strength might be the most important. For others, it might be more important to prioritize the adhesive strength or durability over the strength of the tape itself. Be sure to consider what you are looking for before you buy tape.
Lamination vs. co-extrusion
Duct tape can be constructed differently by manufacturers. There are two methods used to make duct tape: lamination and co-extrusion. Lamination has traditionally been the only method used to make duct tape. However, tape manufacturers have since created an innovative new process called co-extrusion, which offers a number of advantages over traditional laminated tape like improved strength and durability.
Due to the manufacturing process, co-extruded tapes tend to hold together for use in harsher environments. While co-extruded tapes may be preferred for the toughest jobs, they are often limited in color selection and patterns. Understanding your specific application will help you choose the right tape for your job.You can tell the difference between the two just by looking at them: laminated tapes can be identified by a horizontal stripe on their backing, and co-extruded tapes feature a dotted appearance that can be both seen and felt.
If you still need something stronger, look for specialty brands of duct tape that emphasize tensile strength. Some varieties of duct tape are specifically created with strength in mind, and the strongest types can handle the toughest of tasks — even holding hundreds and hundreds of pounds of weight. These types are easily found in stores and can also be found readily online.
