P1, P2 and P3 are versatile electrical insulation materials, which are manufactured using fine layers of phenolic paper. They exhibit high strength and excellent electrical properties coupled with low moisture absorption.
There are a choice of grades dependent upon voltage or other water absorption or insulation criteria. P Grades are used in low temperature and electrical applications where rigid non-metallic insulation is needed.
F Grades are multi-purpose insulation materials manufactured using coarse, medium and fine weave phenolic cottons, which have excellent strength properties and very good wear resistance characteristics.
