Is Bakelite better than plastic?
Bakelite is resistant to heat and chemical actions and also it is non-flammable. The dielectric constant of Bakelite ranges from 4.4 to 5.4. This is a cheap material and more versatile than other plastics.
What are the disadvantages of Bakelite?
However, bakelite had its obvious limitations: it was resistant, but fragile. The hardness and lack of flexibility that made it suitable for certain uses was a drawback for others. “You couldn’t make packaging from Bakelite, or fabric, or anything transparent, super lightweight things,” Freinkel sums up.
