Polyurethane is an everyday plastic material which takes on many various forms. Since its invention in 1940, polyurethane has been used when creating a wide range of items from one of its first uses in World War II aeroplane wings, to surgical equipment and children’s toys now. It continues to be a useful material and is still being adapted for contemporary technology.
How is it made?
Based on its chemical structure, the substance is categorised as a polymer – a large molecule composed of many repeated smaller ‘monomer’ units. The manufacturing process combines two types of (monomer) compounds, diisocyanate and a diol, through a chemical reaction. This makes the basic material which can then be adapted to suit the purpose.
It is a flexible and resilient manufactured material which is known for its durability. The basic material can be stretched, scratched or smashed and still remain fairly indestructible. Polyurethane can take the place of rubber, metal, wood, cotton or paint, to fit thousands of purposes across all lines of industry.
Resembling other kinds of plastics, fibreglass or metal, thermoplastics are rigid and smooth. A sealed surface makes them impermeable to water which is essential to their function. They also have various heat-resistant or insulating properties.
Examples of Usages
Polyurethane is used in such a broad scope of everyday items, including:
- cushioning for furniture
- car parts
- industrial machines
- surgical equipment
- protective coating for wood
- rollers and tyres
- shoe soles
- children’s toys
- building insulation
- insulation of refrigerators and freezers
