Bakelite sheet: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.
Features:- Excellent dielectric properties
- Good mechanical strength
- Intermediate electrical insulation
- Anti-static
Applications:- Suitable for fixture,mold plate,motor,mechanical mould,PCB,ICT fixture,grinding machine,drilling machine etc.Also fit for cams,gears,special machinery surfaces,insulators,relays,switches,terminal strips.
