As technical coordinator, Inspiralia has worked with several industrial and technological partners to perform different strategies for developing a highly effective encapsulation system for TDI isocyanate monomer.
The objective: to produce a homogeneous reactive mixture for PUR foaming purposes where reactants are physically separated by using functionalised microcapsules of isocyanate conveniently dispersed on polyol mixture component. For this purpose different shell materials, conditions, reactants, releasing and breakage capsule methods have been tested and developed during the curse of the project.
The new reactive system increases the mixture reactivity due to the performed compatibility and hence, homogeneity between isocyanate and polyol components while decreasing the exposure of workers to harmful emissions by lowering the residual monomer content on the foam, avoiding the emissions and migration of such components from foams.
In addition, the mixing system will decrease the generated waste due to bad cell homogeneity and product density as a consequence of bad mixing. As a result, high quality polyurethane foams has been produced with improved properties compared to those currently available in the market.
Inspiralia can offer your company tailored solutions in micro and nanoencapsulation technologies for a wide range of applications: cosmetics, nutritional, medicine, insecticides, coatings, UV protection, textiles, self-healing materials and many others, including different types of compounds, from monomers, catalyst and PCM´s (phase change materials) to essenctial oils, fragrances, vitamins, enzymes, antibodies, proteins, etc.
