Samples of plastic insulating material

Made 1946

Plastics have been described as “materials that can be moulded or shaped into different forms under pressure or heat.” They were a cultural phenomenon in the twentieth century when they changed the way objects were produced, designed and used. It was also in the twentieth century that most plastic products moved away from natural raw materials to synthetically produced ones.

The museum’s plastics collection began in the 1930s with the acquisition of specimens of plastic raw materials and finis...

Sample of urea-formaldehyde insulating material, 'Bumaxit', maker unknown, Switzerland, 1946

Production

Urea, also known as Carbamide, is an organic compound that is very soluble in water. It was synthesised in 1828 by Friedrich Wöhler. Urea moulding powders are used in the manufacture of plastics: 'Urea and formaldehyde are reacted with a catalyst to form a water soluble resin.' The result is a water-white and translucent powder that is suited to make colourful plastic products. Some qualities of these moulding powders are that they are non-flammable, resistant to corrosion, and free from odour and taste, making them ideal for many domestic applications.

Resin products made by heating urea with formaldehyde were patented by Hanns John in 1918. The first commercial moulding powders using thiourea and formaldehyde were developed by the British Cyanides Company (later to become British Industrial Plastics Ltd). These moulding powders became known as 'Beetle' moulding powders.
