Ravecarb are polycarbonate diols (PCD), which are aliphatic polycarbonate with molecular weight around 500-3000, and two terminal OH groups. PCD are increasingly well known and used intermediates for high performance PU systems in sectors like synthetic leathers, various coatings and resins for flooring or wooden surfaces, paints, elastomers, adhesives, sealants, liquid inks for printers, etc. In all those sectors PCD are undisputedly considered as the ultimate solution in terms of quality improvement for:
- mechanical resistance;
- chemical resistance and stability;
- elongation property;
- UV resistance;
- anti-scratch and anti-stain properties;
- “cosmetic touch” in the production of high quality synthetic leathers.
