XXXP Paper Phenolic is ideally suited for applications requiring high insulation resistance and low dielectric losses under severe humidity conditions. XXXP has better electrical properties than XXX grade and more suitable for hot punching. It is intermediate between XXP and XX in punching characteristics.
Grade XXXP. Paper-reinforced laminate similar to Grade XXX, but bonded with plasticized resin; low in dielectric losses; low cold flow; recommended for punching of parts requiring high insulation resistance at high frequencies and high humidity; should be punched hot.
