Polypropylene Carbonate Diol

Product Overview
Polypropylene carbonate diol is a high molecular weight material synthesized through the ring-opening polymerization of propylene carbonate monomers with dihydroxy or trihydroxy initiators under specific conditions. Its physical properties can vary depending on the type and amount of starting materials. This product is primarily used for resin modification, effectively improving the flexibility, flowability, low-temperature impact resistance, moldability, and mechanical properties of resins. It also boasts high cohesive strength, strong adhesion, good abrasion resistance, and strong oil resistance, making it widely applicable in the polyurethane industry. Additionally, polypropylene carbonate diol has excellent biocompatibility, making it suitable for biomedical applications.
