Mattresses & pocket springs

A selection of hot-melt adhesives for the assembly gluing of mattresses, characterized by strong bond and good adhesion to flexible foam and other upholstery materials.

Modern mattress production uses special cores made from layers of pocket springs.

For glueing pocket springs, MITOL produces a wide range of high-quality EVA and polyolefin-based hot melt adhesives, that can be used on both automatic and semi-automatic production lines.

All developed adhesives for assembly glueing of pocket springs meet the high requirements of the standard OEKO-TEX 100, class 1, which means that the total content of polycyclic hydrocarbons (PAH) in the adhesive is less than 5 mg/kg. Polyolefin-PP-based adhesives are considered to be recyclable with non-woven material, which contributes to the recycling efficiency of the final product.

In addition to EVA and polyolefin-based hot melt adhesives, MITOL also offers several solutions for APAO-based hot melt adhesives which can be used for the glueing of mattresses. APAO-based adhesives are characterised by long open time, and good adhesion and they develop a strong bond in all combinations of flexible foam and different upholstery materials (felt, non-woven, jute, coconut fibres). APAO-based hot melt adhesives are mainly used for manual or automatic applications, where a very long open time and good initial hot tack are required.
