GPE: light compounds of modified TPU with a low specific weight and an extraordinary resistance to abrasion.
Those are compounds realised thanks to the big experience in technologies related to rubbers with low density which offer constancy in performances and results.
They are particularly suitable for high fashion, sports and technical shoes. GPE compounds weigh nearly 50% less than classical compact TPU.
Resistance to abrasion is between 120 and 180 mm3 (DIN53516). The soles realised with GPE compounds do not mark the floor: the effect of thermo-abrasion typical of thermoplastic materials is practically cancelled.
The soles do not need to be halogenated before the gluing and the value of resistance to gluing is very high.
When correctly moulded those materials do not present any inner hole in the soles and are suitable for lateral milling.
