Bakeliittilevyjen

Bakeliittilevyjen, commonly known as Bakelite sheets, are a type of laminate material made from phenolic resin and paper or fabric. Bakelite itself was one of the first synthetic plastics, developed by Leo Baekeland in 1907. These sheets are created by impregnating layers of paper or fabric with phenolic resin and then compressing them under heat and pressure. This process results in a hard, rigid, and durable material with excellent electrical insulating properties.

The properties of Bakelite sheets make them suitable for a variety of applications. They are known for their good mechanical strength, resistance to heat and chemicals, and low electrical conductivity. Historically, Bakelite sheets were widely used in the electrical industry for insulating components, switchboards, and circuit boards. They also found use in mechanical applications due to their durability and wear resistance, such as in gears, bushings, and structural parts.

While the use of Bakelite sheets has declined somewhat with the advent of newer composite materials and plastics, they are still found in certain specialized applications where their unique combination of properties is advantageous. Their historical significance in the development of plastics and their enduring utility in specific industrial sectors make them a notable material in engineering and manufacturing history. The manufacturing process involves careful control of resin impregnation, layering, and curing to achieve the desired material characteristics.
