Polyurethane types formed by polyol and isocyanate, and their uses from furniture to automotive, insulation to decoration.
Polyurethane (PU) is a polymer formed by the chemical reaction of polyol and isocyanate. Depending on the formulation it can be made as soft foam, rigid insulation foam, integral skin, elastomer or coating.
Main types
- Flexible foam: Seats, mattresses, pillows
- Rigid foam: Cold-room panels, boiler and pipe insulation
- Integral skin: Armrests, steering wheels, decorative parts
- Elastomer: Buffers, wheels, technical parts
How is it produced?
The two components are mixed in a polyurethane machine at a set ratio and temperature and injected into a mould or poured openly. In series production, high-pressure machines are preferred for their precise ratio, homogeneous mixing and low scrap.
