L'acier plastique, le POM (polyoxyméthylène), est un nouveau type de matériau largement utilisé ces dernières années en raison de ses excellentes performances, de sa facilité de mise en œuvre et de ses propriétés antifriction, de résistance à l'usure et à la fatigue. De plus, sa rigidité, son élasticité et sa taille sont relativement stables. Il est devenu le meilleur substitut aux métaux non ferreux tels que le cuivre, le zinc et l'aluminium. Avec l'émergence du POM, il a rapidement été appliqué aux fermetures à glissière, marquant ainsi une avancée majeure dans le domaine des fermetures à glissière.
