Polycarbonate Diol (PCDL)
High-Performance Polyol for Premium Polyurethane Applications
Product Overview
Polycarbonate Diol (PCDL) is a high-performance polyol widely used in advanced polyurethane systems. Compared with polyester and polyether polyols, PCDL-based polyurethanes offer superior hydrolysis resistance, excellent mechanical strength, outstanding weatherability, and long service life.
Our PCDL is manufactured under strict quality control, ensuring stable molecular weight distribution, low acid value, and consistent batch-to-batch performance, meeting the requirements of coatings, adhesives, elastomers, sealants, and synthetic leather applications.

Key Advantages
- Excellent hydrolysis resistance and water stability
- Superior abrasion resistance and mechanical strength
- Outstanding UV and weather resistance
- Low viscosity, easy processing
- Enhances chemical resistance and durability of PU systems
- Suitable for high-end and long-life polyurethane products
Typical Applications
- Polyurethane coatings (industrial, automotive, protective coatings)
- High-performance adhesives & sealants
- TPU / CPU elastomers
- Synthetic leather & artificial leather
- PU films, inks, and specialty resins
