Polyurethane (PUR and PU) is a polymer composed of organic units joined by carbamate (urethane) links. While most polyurethanes are thermosetting polymers that do not melt when heated, thermoplastic polyurethanes are also available.
Polyurethane polymers are traditionally and most commonly formed by reacting a di- or tri poly-isocyanate with a polyol. Since polyurethanes contain two types of monomers, which polymerise one after the other, they are classed as alternating copolymers. Both the isocyanates and polyols used to make polyurethanes contain, on average, two or more functional groups per molecule.
Polyurethanes are versatile, modern and safe. They are used in a wide variety of applications to create all manner of consumer and industrial products that play a crucial role in making our lives more convenient, comfortable and environmentally friendly.
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.
The uses of polyurethane ranges from flexible foam in upholstered furniture, rigid foam for insulation in walls and roofs, TPU used in medical devices and footwear, to coatings, adhesives, sealants, and elastomers used on floors and automotive interiors. The base year considered for the study is 2015, and the forecast has been provided for the period between 2016 and 2021.
The future of the global MDI based polyurethane market is positive with opportunities in building and construction, appliance, transportation, furniture and bedding, footwear, packaging, and general & industrial engineering industries. The major driver for growth in this market is increasing demand for higher thermal insulating materials in building and construction, home appliances, and transportation sectors.
The polyurethane (PU) market size was USD 53.94 billion in 2015 and is projected to grow at a CAGR of 7% from 2016 to 2025. High demand for lightweight & durable materials from end-use industries such as furniture, construction, electronics & appliances, automotive, footwear & packaging has driven growth in recent years.
