What is Bakelite Powder?
Bakelite powder is a thermosetting phenol-formaldehyde resin in powder form. It’s used as a molding compound to make various hard, durable plastic products.
Chemical Composition: Phenol + Formaldehyde + Fillers (like wood flour, asbestos, or mica)
Invented by: Dr. Leo Baekeland in 1907 (first synthetic plastic)
Type: Thermosetting polymer (cannot be remelted once set)
