According to International Sleep Products Association, about 39 million mattresses were sold in the U.S. in 2015. Ranging from innerspring, foam and airbeds, it’s estimated that each of them used one-half to three-quarters of a pound of mattress adhesive during manufacturing.
Responsible for holding the mattress layers together, these adhesives play an important role in mattress construction. Take a look at two prominent types of mattress adhesive technologies, and understand which works best for your needs before making a decision.
Water-based mattress adhesives’ main pro is that they are environmentally friendly and safe for operator use.
However, as water-based products rely on evaporation to set, they tend to take longer to form a bond. This can slow down manufacturing processes, so it’s important to understand that ahead of time.
Additionally, water can get trapped in the mattress packaging used for transportation and storage, causing potential mold. Ensure to limit the likelihood for trapped moisture when using these adhesives in mattress assembly.
Hot Melt Adhesives
Hot melt adhesives are becoming an increasingly popular option in mattress assembly. Due to their fast set speed, hot melts are quick to form a bond and solidify. It’s important to note that with hot melt adhesives, bonds are formed as heat dissipates.
Additionally, these solutions offer rapid initial tack, further aiding in faster assembly processes. By not needing a carry agent, as a result of their tack, it also means less initial material is required in assembly.
While a disadvantage to hot melt adhesives has traditionally been their potential to make a crackling noise once dried, recent formulations have solved this issue. As a result, it’s important to note that these newer adhesives are not noisy for end-use consumers.
Bostik manufactures smart hot melt adhesives specially formulated for mattress assembly applications, such as:
- Bonding foams
- Pocket coil assemblies
- Bonding fabrics and fibers
In addition to aiding in fast assembly lines, these solutions are able to bond to more complex mattress construction and new materials. For more information on how our mattress adhesives can help your company, call 800-7-BOSTIK, or visit www.bostik.com/us.
