MONO DENSITY RUBBER: (generally an injection molded outsole). Non-vulcanised caoutchouc stinks and is not resistant to cold temperatures, so it is submitted to a vulcanization process which makes it very resistant. Rubber outsoles are exceptionally sturdy: temperature-resistant from -30 up to 300°C, hard to penetrate from sharp objects and resistant to fuel, oil, microbes and numerous chemicals. However, rubber is heavier than PU and TPU, and is less flexible when submitted to cold temperatures. The abrasion resistance of rubber is from 100 to 130mm3. RECOMMENDED USAGE: It is a compact and heavy material so it is not the best choice if you need extremely light footwear.
PU/RUBBER: (generally an injection molded outsole). Keeping the properties of rubber for the outsole, in this type of outsole the midsole is of PU so the footwear is lighter. The PU in this case is the weak point in the toughest situations where rubber's performances are better. RECOMMENDED USAGE: indoor and outdoor, in contact with hydrocarbons, chemicals, acids. It is a compact and heavy material, so to make it lighter it is joined with PU.
EVA/RUBBER: EVA is elastic and tear- and slip-resistant. When used to make shoes, EVA is used as cushioning material in the midsole. However, nowadays EVA is also used for creating midsoles in safety footwear, placed in cemented outsoles between the upper and the outsole (usually rubber). RECOMMENDED USAGE: indoor and outdoor, in contact with hydrocarbons, chemicals, acids. It is a compact and heavy material, so to make it lighter it is joined with EVA.
