LT-Pur is a thermoplastic polyurethane elastomer (TPU), which has been modified to operate at low temperatures (to about -50°С) without loss of main physical and mechanical characteristics. Compared with Pur, LT-Pur has higher elasticity (better than silicone rubber MVQ).


LT-Pur can be used in the same sphere of application as Pur, but at lower temperatures, primarily in cold climatic zones.
