Structural polyurethane
Structural polyurethane is an easily processable thermosetting polymer with excellent technical characteristics that, depending on the formulation, takes on different shapes and functions. This makes this material highly appreciated on an industrial level because its ease of use allows for the widest possible creativity.
The characteristics of structural polyurethane
Structural polyurethane can be used in various sectors due to its special qualities, which are mainly:
- Surface hardness
- Surfaces free from suction and deformation, even in the presence of ribs and reinforcements
- Resistance to chemical and biological agents
- Mechanical resistance
- Thermal insulation characteristics
Polyurethane Baydur
Baydur structural rigid polyurethane, is a medium to high density rigid polyurethane system around 650-1050 kg/m3), suitable for supporting heavy weight loads, and allows objects with different side thicknesses to be produced. It is obtained through the chemical reaction of (Polyol and Isocyanate) which results in the formation of a foam that is solidified inside suitable moulds. Its structure is called ‘Sandwich’ and features a compact outer surface and a porous cell nucleus. This structure allows many design benefits: from high mechanical strength to low specific weight. The moulded elements allow objects with side thicknesses ranging between 4 and 20 mm to be produced. As it is processed with a high density that allows it to be highly resistant, this material is mainly used for the production of furniture items, casings for electro-medical equipment, coffee machine casings, etc

Polyurethane Baydur 110
Baydur 110 is a compact polymer for RIM that enables low-cost production of items with high stiffness and mechanical strength. RIM (Reaction Injection Moulding), is a thermoplastic injection and reaction moulding method. The process involves the use of two liquid components mixed before being injected into the mould. An exothermic polymerisation reaction then takes place in the mould until the material hardens. Accurate mould temperature control is maintained during moulding to avoid viscosity and density imbalances. The technical characteristics of the product will vary depending on the dosage.
Technical information:
- Density of printed material 1100 g/l
- Side thickness 3-12 mm
- Minimum draft angle 1°
- Plastic shrinkage 0,5-0,8%
- Shore hardness D 75-77
- Tensile strength 50 MPa
- Bending strength 58 MPa
- Elongation at break 14%
