Understanding Bakelite

Bakelite is the world's first synthetic polymer, known for its unique three-dimensional structure formed by benzene rings and strong covalent bonds. Unlike other polymers, Bakelite cannot be melted and reshaped, making it a durable material. Initially developed as a synthetic shellac, Bakelite found numerous applications due to its electrical insulation and thermal properties. It was considered for making pennies during WWII and is known for its use in retro 50s objects. Bakelite's strength, resistance to heat and scratching, and ability to be molded into various shapes make it a versatile material.
