C.O.I.M. LARIPUR® LPR72D25 Special Adipate Ester Polyurethane
Categories:	Polymer; Thermoplastic; Elastomer, TPE; Polyester, TP; Polyester Thermoplastic Elastomer; Polyurethane, TP
Material Notes:	Description: The products of the LARIPUR® line are thermoplastic polyurethanes. These products combine the technology of thermoplastic products with the features of polyurethanes: Excellent abrasion resistance Great flexibility with constancy at temperature variations Good compression resistance Good water and light resistance Good resistance to oils, fats and to many types of solvents Series 25 Special Adipate Ester: These products are based on saturated polyesters. Products are based on saturated polyester. The features are similar to those of Series 20 but, by comparison, they are characterized by a higher resistance to hydrolysis and improved flexibility at low temperatures.
