The plastic used for pressure cooker handles and other heat-insulating applications, and which was one of the first man-made plastics, is Bakelite.
Bakelite (Polyoxybenzylmethylenglycolanhydride) is a thermosetting plastic developed by Leo Baekeland in 1907. It was one of the first plastics made from synthetic components. It is known for its excellent electrical insulation and heat-resistant properties, making it suitable for handles of cookware, electrical fittings, and other applications requiring heat resistance.
