Polycarbonate diols are high-performance polyurethane core soft segment raw materials, with molecular chains containing highly stable carbonate ester groups  Compared with ordinary polyester and polyether polyols, they have outstanding comprehensive properties in hydrolysis resistance, wear resistance, weather resistance, and chemical resistance  They are widely used in water-based polyurethane, elastomers, coatings, synthetic leather, adhesives, and other fields; At room temperature, it is in a liquid state, and by copolymerizing two or more types of diol monomers, the crystallinity of the molecular chain is disrupted, greatly improving processing convenience 

Excellent low-temperature toughness, less prone to brittle cracking at low temperatures, and better softness; It has good compatibility with various solvents and resins, and can be fed without melting, simplifying the production process  Retain the excellent hydrolysis and aging resistance basic characteristics of PCDL, comprehensively balanced  Suitable for soft coatings, water-based PUD, films, low temperature resistant synthetic leather and other products
