Paper base insulation board paper phenolic bare board pcb
Bakelite sheet is a hard, dense material made by applying heat and pressure to layers of paper or glass cloth impregnated with phenolic resin. These layers of laminations are usually of cellulose paper, cotton fabrics, synthetic yarn fabrics, glass fabrics or unwoven fabrics. When heat and pressure are applied to the layers, a chemical reaction (polymerization) transforms the layers into a high-pressure thermosetting industrial laminated plastic.
Paper base insulation board feature:
High mechanical properties, and oil resistance and certain dielectric property.Thermal rating is 120, and temperature resistance :130 centidegrees
