Shore A: A35
Density: 0.20 g/cm³
Sheet size: 940 x 900mm

Heating Guide:

The ideal temperature for thermo-moulding Aortha EVA depends on the material thickness and hardness.

The standard principles would be:

Shore A25-A35 and 15mm EVA material: 100-130ºC temperature during 30 to 90 seconds exposure.

It is important to indicate the aforementioned conditions should be adjusted according to the following patterns:

The thinner the material the lower the temperature or the exposure timing. The only effective way to determine heating times based on variable thickness and sheet size, is to test in stages based on the above guidelines.

The heat source is also important; a direct infrared radiation will be much more aggressive than heating a piece with a circulating air system, meaning the temperature should be adjusted accordingly. Again, test in stages as per above.

In general, EVA copolymers should not be extruded hotter than 200°C since degradation may occur.

Degradation products include the elimination of acetic acid, which can account for a “vinegar” odour and corrosion of some materials.
