ABOUT US
Advanced Materials Research Group of Łukasiewicz Research Network — Institute of Heavy Organic Synthesis “Blachownia” specializes in developing of:
- technologies for producing and modification of bio- and fossil-based basic epoxy resins, epoxy vitrimers and glycidyl ethers,
- technologies for producing and modifying formaldehyde-free lignin resins,
- developing technologies for manufacturing polyurethanes (isocyanate and non-isocyanate),
- new types of fiber-reinforced, multi-material and high-filled biocomposites (prepregs, SMC, BMC)
- modification and processing of materials based on thermoplastic biopolymers,
- bio-based materials (alginates, starch, cellulose, chitosan, etc.) for coating applications, including PFAS-free, antibacterial and water/oil resistant coatings,
- plastic materials recycling.
OUR IDEA
Approximately 90% of the global production of polyurethanes is based on two isocyanate compounds: methylenediphenyl-4,4′-diisocyanate (MDI) and 2,4-diisocyanatotoluene (TDI). Due to their high reactivity, MDI and TDI exhibit strong irritant and toxic effects, both during application and synthesis, which involves highly toxic phosgene as a raw material. For these reasons, in the near future, the use of isocyanates will become more difficult due to legal and health-related concerns.
Łukasiewicz – ICSO “Blachownia” developments address green chemistry based, sustainable-by-design production of polymeric materials, proposing bio-and waste-based, isocyanate-free alternatives to traditional polyurethanes. Polyhydroxyurethane polymers, also known as non-isocyanate polyurethanes (NIPU, PHU) are obtained by reacting cyclic carbonates with polyamines containing primary amino groups. This offers a sustainable pathway to replace isocyanate and polyol-based polyurethanes in some applications, like foams, adhesives and coatings.
