Polyurethane is a plastic material with very interesting chemical and physical properties. Some of the properties found in polyurethane moulded objects are listed below.
- High resistance to mechanical stress.
- High surface hardness.
- High resistance to moisture.
- Wide temperature range that can be endured without changes in shape or physical characteristics
- Perfectly paintable with all types of coating
- Chemically inert in contact with many organic and inorganic substances
- Excellent electrical and acoustic insulation
Polyurethane is also a very versatile material because it is possible to:
- produce complex profiles, even large ones, with varying thicknesses,
- create lightweight products,
- co-mould fastening solutions such as metal or plastic threaded inserts (lead screws, pins, snap fasteners, etc.),
- produce items with an attractive design even with undercut parts,
- apply a variety of surface finishes (glossy, matt, embossed, water transfer dipping, etc.),
- lower investments in tooling; depending on the print runs and characteristics of the objects to be moulded, there is a choice between resin moulds or aluminium moulds.
