What is a Polyurethane?
Polyurethane refers to a class of polymers composed of organic units joined by carbamate links. In contrast to other common polymers such as polyethylene and polystyrene, polyurethane is produced from a wide range of starting materials.

Is polyurethane cheap to produce?
One of the first things to consider when reviewing polyurethane parts cost is that the base chemicals used in producing PU are readily available and cheap.
The unit cost is therefore based almost entirely on the amount of time and expertise needed to create the perfect part to match your specifications.
What are the raw materials for polyurethane?
Polyurethane Raw Materials
- Isocyanates. Polymeric MDI. High functional oligomer and isomer-containing, solvent-free 4,4′- diphenylmethane di isocyanate with average functionality 2.7.
- Polyols & Polyether amines. Polyether polyols.
- Polyurethane Systems. Filter Systems.
What is needed to make polyurethane?
Polyurethanes are formed by reacting a polyol (an alcohol with more than two reactive hydroxyl groups per molecule) with a diisocyanate or a polymeric isocyanate in the presence of suitable catalysts and additives.
How long does polyurethane last?
For example, under normal wear and tear, a durability of more than 50 years can be expected for polyurethane insulation systems for buildings, more than 25 years for polyurethane used for insulation of refrigerators or more than 20 years for the application of polyurethane in vehicles bumpers.
