- In detail
The wrapper of "Polilen-0B" - is used in coverings as the top (protective) wrapping layer in anticorrosive systems for their protection against mechanical damages.
It is applied in the following anticorrosive systems (designs):
1. The main layer — the Film Polilen 40-LI-63 or Polilen 40-LI-45;
2. A protective layer — the Wrapper Polilen 40-OB-63;
3. A primer — NK-50 Primer.
TAPE TYPE |
The insulating tape Polilen-Ob represents a four-layer tape (a polyethylene basis + the 1st transitional layer + the 2nd transitional layer + a butylrubber adhesive layer) on the basis of termosvetostabilizirovanny polyethylene and butyl rubber, made by method with - extrusions. |
SCOPE |
The tape Polilen-Ob is used in coverings as the top layer intended for protection of an anticorrosive barrier. |
