New Developed Materials In R&D Center Of Leather Chemicals Of Chinese Academy Of Sciences

Based on special molecular design and new polymerization approaches, various materials for leather-making have been developed recently in the R&D Center of Leather Chemicals, Chinese Academy of Sciences (CAS). Some of special materials will be presented here, such as the retanning and finishing agents with a hyperbranched structures, the poly (siloxane-co-acryl ate) emulsion with a high content of siloxane, the scar pastes mainly containing micron size hollow microspheres, etc. All these new developed materials exhibit a high performance in their expected functional properties.
