Polyurethane is a common plastic that appears in many forms and applications. First developed in 1940, it was initially used in World War II aircraft. Today, it plays a vital role in everything from surgical tools and car parts to children’s toys and furniture. Thanks to its adaptability, polyurethane continues to evolve with modern technologies.
How Is It Made?
Chemically speaking, polyurethane is a polymer—a large molecule made up of repeating smaller units called monomers. It is formed by reacting two key ingredients: diisocyanate and a diol. This chemical process creates a flexible base material that can be tailored for specific uses.
The Benefits
Polyurethane is known for its flexibility, resilience, and durability. It can be stretched, scratched, or compressed and still retain its form. Often used as a substitute for materials like rubber, wood, metal, or cotton, it has countless applications across industries.
Thermoplastics
Polyurethane can also take the form of thermoplastics—rigid, smooth materials that resemble plastic, fibreglass, or metal. These surfaces are water-resistant, making them ideal for insulation and protective applications. They also offer various heat-resistant and insulating properties.
Everyday Uses
Polyurethane is found in a wide variety of products, including:
Furniture cushioning
Mattresses
Car components
Industrial machinery
Surgical instruments
Paints and wood coatings
Rollers and tyres
Shoe soles and sportswear
Toys
Building and sound insulation
Fridge and freezer insulation
