Hot melt adhesives are extremely common in the adhesive industry. They’re used for all manner of things and acquired through hot melt adhesive suppliers. Everything from bookbinding to arts and crafts can be accomplished by using hot melt adhesives. They’re also an essential ingredient in the construction of electronics and automobiles as well as appliances and furniture. You probably encounter hot melt adhesives on a regular basis, but you may not be aware of how they’re created by hot melt adhesive suppliers.
Why HMAs Are Simply Better
They offer numerous advantages over solvent-based adhesives, and this includes but is not limited to: no need for curing, VOCs can be reduced or even potentially eliminated, there are typically no regulations about their proper disposal, and they have a much better shelf life than solvent-based solutions. While solidifying, they don’t lose any of their thickness, which is a huge benefit for numerous reasons for hot melt adhesive suppliers.
Ingredients Of Hot Melt Adhesives:
You may be wondering what kinds of hot melt adhesives are out there and how each of them is created. If that’s the case, then you’re in luck:
Polymer Hot Melt Adhesives
These melt adhesives are made from a polymer solution. The higher the percentage of polymer in the solution, the more viscous the solution becomes. This is important to note because the higher the viscosity of your solution, the stronger it will be. It will also be more flexible if you increase the viscosity of the adhesives through your hot melt adhesive manufacturer.
Tackifying Resins
Tack refers to how sticky your adhesive is. The amount of resin that you add to your solution will determine how strong the tack is. If you choose to reduce the tack, then you can add more resin to your solution than if you want increased tack. The kind of resin that you choose can have a big impact on the final product, so be sure to put some care and research into your decision before you finalize it with your hot melt adhesive manufacturer.
Wax
The next thing that is done, is to add wax to the solution. The wax plays an essential role in determining the speed at which it makes a bond. It also determines how long it takes to reach the correct bond strength. Wax also influences the strength of the bond and the resistance to heat. This is an important step, and care needs to be taken for optimal results.
Additional Additives
Two other important additives are plasticizers and antioxidants. Plasticizers can make sure that the product has the strength and flexibility you’ll need to ensure a healthy binding. Antioxidants help protect the binding the same way they protect our bodies.
