Today‘s variety of mattresses is reaches from pocket-spring mattresses over latex mattresses to foam mattresses. The material selection is growing and in the same time the construction principles of mattress manufacturing are developing too. A modern mattress is a technical composite material consisting of different layers. This is a challenge for the adhesive industry as all those layers of different materials or compositions have to be bonded. Although bonding of different foams is not new for the mattress industry – the adhesive technology that is in use is now changing.
Different layers of a PU foam mattress bonded with a PU-based adhesive might enable to simplify recycling. But there is more: Especially PUR hot melt adhesive also offer technical advantages in the manufacturing process to optimize efficiency.
