GPE: light compounds of modified TPU with a low specific weight and an extraordinary resistance to abrasion. No blowing agent  to be added because it is already incorporated in the granule. Those are compounds realised thanks to the big experience in technologies related to rubbers with low density which offers constancy in performances and results. GPE compounds weigh is nearly 50% less than classical compact TPU; they have more elasticity, anti-sliding properties and softness. They have a very good resistance to abrasion, to the light and to low temperatures. Totally recyclable, they do not need pre-heating and drying process before use. They can be injected with normal injection machines.
