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. Polyurethanes plastic commonly used in the manufacture of flexible, high-resilience foam seating; rigid foam insulation panels; microcellular foam seals and gasket - in.kompass.com/a/bottles-plastic-for-the-pharmaceutical-and-cosmetic-industry/2071009/
Synthesised polyurethane offers more consistent and predictable properties compared to recycled polyurethanes, which can vary in quality and performance due to the variability of feedstock materials. Additionally, synthesised polyurethane can be tailored to specific applications and performance requirements more easily than recycled polyurethanes. Finally, synthesised polyurethane typically exhibits better mechanical properties and durability than recycled polyurethanes.
Adhesives can be made from a variety of materials, including natural substances like animal-based adhesives (e.g. bone glue) and plant-based adhesives (e.g. starch-based adhesives), as well as synthetic materials like acrylics, epoxies, and polyurethanes. The choice of materials depends on the desired properties of the adhesive such as strength, flexibility, and resistance to various environmental factors.
An example of a catalyst is platinum, which is used in catalytic converters to facilitate the conversion of harmful gases into less harmful emissions in vehicles. Catalysis allows chemical reactions to occur more quickly and efficiently, without being consumed in the process.
Polyurethane (PU) coating is a rigid and durable material commonly used for waterproofing and protection, while thermoplastic polyurethane (TPU) coating is flexible and elastic, often used for impact resistance and shock absorption. TPU coatings are more abrasion-resistant and provide better flexibility compared to traditional PU coatings.

Yes, polyurethane is a synthetic material. It is a polymer composed of organic units linked by carbamate (urethane) links.
