Hot melt adhesive for the mattress industry

Hot melt adhesive for mattress assembly

Hot melt adhesives make the assembly of mattresses faster and easier. Because they are easy to handle, many manufacturers use adhesives to connect the foam around the mattress springs, attach the cushioning foam and insulating materials to the interior of the mattress body, and keep the cushioning and decorative fabrics at the top of the pillow in place.

This is very important for the more complex mattresses that are assembled nowadays. Nowadays, many mattresses require additional comfort layers such as gel and foam, which need to be connected to the internal mattress structure using a non-toxic adhesive system.

Senlai hot melt adhesive for mattresses has been widely used in mattress assembly due to its non-flammable and non-toxic properties as well as its fast curing time. Now, its tensile properties have also been significantly improved.

Advantages of hot melt Adhesive for mattresses

If you are currently using a water-based hot melt adhesive system, you will find that hot melt adhesive particles are easier to use. Because this product doesn’t require mixing or cleaning up excess waste, it won’t be so chaotic. This means faster production line speeds and higher productivity. In addition, hot melt adhesive particles are stronger and more reliable – reducing the risk of improper bonding of mattress components.

Specifications of hot melt adhesive for mattresses

The four main specifications can help you determine whether it suits your needs.

Melt viscosity (MV)

refers to the fluidity of polymers at a certain temperature. Melt viscosity is measured in centipoise or cps.

2. Global Softening Point (RBSP)

Measure the heat resistance of hot-melt materials. In the mattress industry, the softening point should not be too high to avoid using fabrics and foams that may overheat or even catch fire.

3. Opening Hours

This will tell you how long the adhesive can remain in the air before it solidifies. Many adhesives in the mattress industry require a long open time because workers need some time to position the components together.

4. Density

It can measure the hardness of polymers and indicate their durability after curing.
