The traditional frozen rubber, our CER 01, being very reactive, has to be stored
in freezer at -15 / - 20°C.
We recommend our valuable customers to take out from the freezer
Only the quantity which has to be pressed in a short time, not the complete package.
At these conditions the material preserves its softness and characteristics
for months.
In order to avoid bubbles on the vulcanized rubber surface
it is good habit to dry the rubber sheets from the moisture before pressing.

Our long life rubber, Cer 03/C, due to its different polyurethane’s nature , it is not damaged
because of moisture and has no storing problems at all.
For this reason the storing and the shipping is at room temperature and the shelf life is
6 months minimum.
