PLACCEL 220CPB is a polycaprolactone diol and its molecular weight is 2000.Since it is manufactured by the ring opening polymerization of epsilon of epsilon-caprolactone,exact control of hydroxyl group value is possible.The recommended applications of the polyurethane made from PLACCEL 220CPB are elastomer,synthetic/artificial leather,adhesive,binder and spandex.Polyurethane elastomers made from PLACCEL 220CPB has good property of compression set resistance because of its narrow molecule weight distribution.PLACCEL 220CPB can improve hydrolytic stability and elastic recovery by its low acid value and chemical structure.
