C.O.I.M. LARIPUR® LPR7025 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.
