1. Define and purpose
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.
II. Characteristics
♦High
mechanical properties, and oil resistance and certain dielectric property.
♦ Good electrical property
♦ Temperature resistance : 140centidegrees, warp degree: ≤3‰
