Polycarbonate Diol (PCDL) – High Performance Polyol for TPU, PUD and Polyurethane Elastomers
Reliable Polycarbonate Diol Supplier for High-Performance Polyurethane Applications
BEIQIAO supplies high-performance Polycarbonate Diol (PCDL) for manufacturers requiring excellent hydrolysis resistance, weather resistance, mechanical strength and long-term durability in polyurethane systems.
Compared with conventional polyester polyols and polyether polyols, PCDL provides superior resistance to water, heat, UV and chemicals, making it an ideal soft segment material for demanding polyurethane applications including TPU, PUD coatings, synthetic leather, adhesives and cast polyurethane elastomers.
With stable supply capability and customized technical support, we help customers select suitable PCDL grades according to their formulation requirements.
What is Polycarbonate Diol (PCDL)?
Polycarbonate Diol (PCDL) is a polyester-type diol containing carbonate bonds in the molecular chain.
As a polyurethane raw material, PCDL reacts with isocyanates such as MDI, HDI, IPDI and H12MDI to produce high-performance polyurethane materials.
The carbonate structure provides improved molecular stability compared with traditional ester bonds, resulting in:
Excellent hydrolysis resistance
Outstanding weatherability
High mechanical strength
Good abrasion resistance
Better thermal stability
Long service life under harsh conditions
