Prepolymers

Prepolymers are compounds that enable modifying of isocyanates with high molecular weight alcohols or other compounds with carboxyl or amine groups, to obtain the desired properties in the target system. The isocyanate prepolymers contain reactive NCO groups that react with hydroxyl or amine groups, resulting in chain extension and the formation of a finished material. They are characterized by the ability to regulate the content of free isocyanate groups (-NCO) as needed. Representatives of this group of compounds are prepolymers based on aromatic isocyanates (MDI, TDI) or aliphatic (IPDI, HDI, H12MDI etc.).

Applications of prepolymers

Pre-polymers are present in one- and two-component systems due to a wide range of applications. In the case of two-component systems, they are used as components of systems for the production of moulded and integral flexible foam. One-component prepolymers are used in glue applications, among others in construction industry: for gluing wood, parquets and fibreboards as well as for joining rubber granules.
