Polycarbonate diol
- Applications of Polycarbonate diol
* Compared to glycol of general polyester and polyether families, this product has excellent mechanical performance, hydrolysis resistance, thermal stability, weather and solvent resistance.
* Application in products that need high durability, i.e. synthetic leather, artificial leather, spandex, coating, bonding agents, elastomers, bonding agents for magnetic material and thermo-plastic resins.
