Description:        Epsilon Caprolactone series products could greatly improve the performance of the downstream polyurethane, coatings, adhesives and other products. Before the localization, they are used for high-end products only.         Under the background of the implementation of the new national environmental protection policy and in the world, need of the upgrading of the new industry, the market consumption of the products will be greatly improved with the support of the Chinese technology.PCL Polyol apply in PU elastomerPolycaprolactone polyol is by caprolactone monomer, initiators, catalysts formed by the ring-opening polymerization, with a high reactivity, low viscosity, molecular weight distribution narrowly and low acid value and low water content, the products are mainly used in polyurethane elastomers, coatings and adhesives and other fields. In the polyurethane elastomer, most polycaprolactone polyols obtained elastomer to improve its tear resistance, and with the polycaprolactone polyols in PU elastomers obtained good hydrolytic stability and low temperature flexibility, which are far superior than usually polyether and polyester as the raw material of the PU elastomer, its temperature resistance, mechanical properties and solvent are also superior to other polyurethane rubber. BenefitsHave a lower density than those derived from polyadipates Can be used with both aliphatic and aromatic isocyanates Outstanding resilience giving elastomers with low hysteresis properties All primary hydroxyl groups ensure consistent and fast reactions Very good low-temperature flex fatigue performance Low polyol viscosity for ease of processing Excellent cut and tear properties Good hydrolysis resistance High abrasion resistanceIn addition, the lower molecular weight polycaprolactone diols and triols can be used as chain extenders in polyurethane formulations.
