types of fillers and are checked for their resistance to chemicals or other
factors that may exist under the ground. A relevant table is available below.
At most of these products is possible the

surface is specially processed (corona treatment) so to succeed permanent

Finally the color additives are chosen so to
keep and maintain the color stability for very long period.
