Polyurethane (PUR and PU) is a polymer composed of a chain of organic units joined by carbamate (urethane) links. While most polyurethanes are thermosetting polymers that do not melt when heated, thermoplastic polyurethanes are also available.
In the industrial and industry context, "polyurethane" refers to a type of polymer that is commonly used in the manufacturing of various products due to its versatility and durability. Here are some examples of the use of polyurethane in different industries:
- Construction: Polyurethane foam is used as insulation for buildings, and polyurethane coatings are used for concrete floors to protect them from wear and tear.
- Automotive: Polyurethane is used in car parts such as seats, bumpers, and dashboards due to its durability and resistance to wear and tear.
- Footwear: Polyurethane foam is commonly used in the soles of shoes to provide cushioning and shock absorption.
- Furniture: Polyurethane foam is used in furniture cushions for its comfort and durability.
- Sports equipment: Polyurethane is used in the manufacturing of sports equipment such as skateboards, surfboards, and snowboards for its strength and durability.
Similar materials that are used in the manufacturing of various products include:
- Polyethylene: A plastic material that is commonly used in the production of plastic bags, bottles, and packaging materials.
- Polypropylene: A thermoplastic polymer that is commonly used in the production of packaging materials, textiles, and automotive components.
- PVC (Polyvinyl chloride): A synthetic plastic polymer that is commonly used in the manufacturing of pipes, electrical cables, and flooring.
- Epoxy: A two-part adhesive that is commonly used in the construction and automotive industries for its bonding strength and resistance to water and chemicals.
- Silicone: A synthetic polymer that is commonly used in the production of adhesives, sealants, and medical implants due to its biocompatibility and resistance to high and low temperatures.
