Medium and high molecular weight systems for the production of soles with optimum resistance to multiple flexing at both low and very low temperatures with hardness ratings ranging from 50 to 60 Shore A and with densities from 0.45 to 0.65 g/cm3.
These systems are particularly suitable for the soles on safety shoes whether they are single or double density. They are also ideal for trekking shoes and all other types of footwear requiring high resistance to flexing and hydrolysis.

The Epaflex PU systems must be stored in a dry and covered area preferably at an ambient temperature around 20 °C and in
any case not at an excessively high or low temperature. Ideally, they should be stored in a cool and ventilated area.

The Epaflex PU systems are formed of three components. The polyols are available in metal drums weighing between 180 and
200 kg, the prepolymers (ISO) in metal drums weighing 240 kg and the catalysts in plastic drums weighing up to 50 kg.
