C.O.I.M. LARIPUR® LPR107-93A Seal Grade TPU
Categories: Polymer; Thermoplastic; Polyester, TP; 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

Seal Grade TPU Products: These products were specially developed for manufacturing hydraulic gaskets or any other heavy-duty application requiring high compression resistance even at high temperature and/or in contact with oils and fats. Two products based on polycaprolactone polyester, E 2202-95A and E 107-93A, and one based on PTMG polyether, E 2203-93A.
