GPU: compounds of TPU (thermoplastic polyurethane)modified with gummy elastomers able to reach the technical and aesthetic characteristics of vulcanised rubber.
They are particularly suitable for high fashion, sports and technical shoes.
Compounds of modified TPU are nearly 15% lighter than compact TPU, with more elasticity and ANTISLIDING properties.
Very low abrasion levels: between 40 and 100 mm3 (in relation to hardness, shoreA DIN53516).
They do not need to be warmed and dried before use.
The soles realised with these materials do not need to be halogenated before the gluing.
They can be injected through normal injection machines used for TR.
