Due to the growing demand for DIN 4102-B2 formulations, Altachem has done a lot of research and development work on economical B2 formulations based on aromatic polyester polyols and MDI prepolymers. Patents have been put into use.
This invention mainly uses prepolymer compounds, and the production of single-component PU foams in aerosol cans, pressure tubes or cartridges is mostly based on MDI and/or MDI/HDI and/or polyether or poly. The ester polyol system replaces the standard MDI or MDI/HDI system.
