Polyurethane Prepolymer Market Outlook: Emerging Technologies and Market Disruptions
Polyurethane prepolymers are an important type of raw material that serve as building blocks for a variety of polyurethane products. They are formed by reacting diisocyanates with polyols to produce polymers with isocyanate groups on the ends of the molecular chains. These isocyanate groups allow the prepolymers to further react and form crosslinked networks. Due to this property, polyurethane prepolymers are very versatile and are used in applications ranging from coatings to sealants to adhesives to elastomers and more. Types of Polyurethane Prepolymers Polyurethane prepolymers can be broadly classified into two main categories based on the type of diisocyanate used in their synthesis: - MDI (Methylene Diphenyl Diisocyanate) based prepolymers: MDI is a widely used aromatic diisocyanate that produces hard yet durable prepolymers. They have excellent heat and chemical resistance but are more brittle compared to other types. Common applications include rigid and semi-rigid f...
