Open-cell Polyurethane foams

HLC items are a family of ether-based open-cell Polyurethane foams, characterized by good resistance to compression.

Asoltex supplies HLC foams in two versions: by itself, with self-adhesive treatment (and PE or silicone paper protective film) or laminated with fabrics using hot melt or adhesive.

The self-adhesive version is ideal as padding in the casual footwear, trekking and safety shoe sector.

The laminated version, available only in densities above 60 kg/m3, is used as a lining in numerous sectors: sports footwear and accessories, orthopedics, cycle and motorcycle accessories.
