First Off, What Is a Differential Adhesive Tape?
Differentials are typically double-sided tapes that have two different adhesives on either side of a carrier. By carrier, of course, we simply mean the structural backing of the tape. Carriers for differential tapes can be made of various materials. That said, polyester carriers tend to be most common.
What Can Differentials Do for My Company?
- Create a better product for your customers
- Save you money on potential processing failures
- Keep you ahead of the competition
Simply put, every tape has specific strengths and limitations based on the type of adhesive they use. So, one of the best perks to using differentials is that you can combine the best attributes of two different adhesives.
For example, let’s say you’re dealing with dissimilar substrates. That is, you’re looking to bond different materials together. One material may be silicone foam, while the other is stainless steel. Using an acrylic-based adhesive tape may work well on the stainless steel, but it won’t stick as well to the silicone foam. The best tape for the silicone foam would definitely be a silicone-based adhesive.
Well, differential tapes are ideal for projects like this that deal with dissimilar substrates. With the above example, you could find the perfect solution with Avery Dennison’s FT 9302 SF differential option. As you can see in more detail below, it uses a general-purpose acrylic adhesive on one side and a silicone adhesive on the other.
Create a better product for your customers. With differentials, you have double the strengths to work with. This perk allows you to get more creative with your product line and offer your customers a better experience.
Save money on potential processing failures. We’ve often found differentials to be one of the easiest solutions to help companies boost their ROIs. Failures during production end up costing you in several ways: labor, cleanup time, and material waste. A lot of the time, differential solutions can make such failures few and far between because we can tailor each side of the tape for optimal performance.
Keep ahead of the competition. Frankly, differentials surprise most people outside of tape manufacturers. When looking for solutions, your competitors may end up unaware of differentials as an option to consider.
