What raw materials are used to make polyurethane?
Polyurethane foams are produced by reacting polyols and diisocyanates, both products often derived from crude oil. The main diisocynate used in the production of flexible polyurethane foam is TDI (Toluene diisocyanate).
Who manufactures polyurethane?
Covestro AG runs its operations through four segments: polyurethanes; polycarbonates; coatings, adhesives, and specialties; and all other segments. The company manufactures PU foams, which are used in various industries, such as automotive, construction, and packaging.
Where do we get polyurethane from?
Various oils used in the preparation polyols for polyurethanes include soybean, cotton seed, neem seed, and castor. Vegetable oils are functionalized by various ways and modified to polyetheramide, polyethers, alkyds, etc. Renewable sources used to prepare polyols may be dimer fatty acids or fatty acids.

How can you prepare polyurethane commercially?
Polyurethanes are prepared by reacting polyols (alcohols with more than two reactive hydroxyl groups in each molecule) with diisocyanates or polymeric isocyanates. Suitable catalysts and additives are used wherever necessary.
Is polyurethane made from petroleum?
The current PU industry is heavily petroleum dependent because the two major raw materials (polyols and isocyanates) are largely petroleum derived as illustrated in Figure 2.
What products are made from polyurethane?
Polyurethane, mostly in the form of flexible foam, is one of the most popular materials used in home furnishings such as furniture, bedding and carpet underlay. As a cushioning material for upholstered furniture, flexible polyurethane foam works to make furniture more durable, comfortable and supportive.
