1. hpl compact laminate overview.
Thermosetting resin impregnated paper high pressure decorative laminate is a decorative material made of surface paper and decorative paper impregnated with amino resin (mainly melamine resin) and base paper impregnated with phenolic resin, laminated and then hot pressed under high pressure, referred to as high pressure decorative laminate (HPL) has high wear resistance, heat resistance, cold resistance, fire resistance and other good physical properties, widely used in wall panels, furniture, etc.
