Product Description:
Polycaprolactone 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.
In the paint, the polycaprolactone polyol can be used as reactive diluent and modifier in polyurethane, acrylic, polyester, epoxy and vinyl coatings. When polycaprolactone polyol is used as reactive diluent, can be used in baking-type melamine and room temperature curing isocyanate cross-linking agent coating. When as a solvent modifier in paint, in addition to reducing VOC, it also can get the necessary balance of hardness and flexibility and does not affect the film properties.
In the adhesive, the use polycaprolactone polyols, polyurethane adhesive system were compared with other polyester polyols have a better color, hydrolytic stability and uniformity.
