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/

What is the difference between a polyurethane PU coating and a thermoplastic polyurethane TPU coating?
A thermoset is a material that cures or sets into a given shape, generally through the application of heat.

A thermoplastic material softens (becomes pliable and plastic) when heated, but it does not cure or set. It can be reheated to be reformed.
