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 mostly solid with a regular molecular structure and strong crystallinity  Excellent mechanical properties, high wear resistance, high tear resistance, high strength, outstanding heat resistance, hydrolysis resistance, and weather resistance, good coating adhesion, and minimal performance degradation of products in long-term humid and hot environments  Suitable for scenarios with strict requirements for durability, wear resistance, and scratch resistance, it is commonly used in high-end coatings, UV resins, wear-resistant elastomers, and high weather resistant synthetic leather
