Breaking strength (Mpa)	76- 83	52- 64	66- 72	53- 72
Breaking elongation (%)	580- 630	880- 970	920- 1040	860- 920

Main features
Compared with general polyester and polyether diols, it shows quite excellent mechanical properties, hydrolysis resistance, thermal stability and weather resistance. and solvent resistance.

Product Application
Artificial leather, synthetic leather, TPU, TPE, spandex, adhesive, two-component polyurethane coating, self-healing PU coating, water-based polyurethane dispersion; elastic feel and wear resistance Paint, etc. Improve durability, light resistance, chemical resistance, hydrolysis resistance, and wear resistance , heat resistance and heat yellowing resistance, PCDL will be the best choice.

Solubility/Dilution
It is compatible with esters, ketones, aromatic hydrocarbons and ether esters. Long-term storage of low solid content solutions may cause turbidity and precipitation. Polyurethane grade solvents should be used (moisture <0.1%, no other reactive impurities).
