Self-adhesive seal for vacuum sealing (15m)

This permanently elastic sealing gasket is made of synthetic rubber for fixing all types of vacuum films on the edges of molds. On one side with removable protective film.

-Good adhesion on a wide range of substrates
-Good UV resistance
-Good formability
-Good chemical resistance to dilute acids and alkalis
-Low resistance to organic solvents
-Easy and accurate to use with little waste and no mess
-Remains flexible throughout its service life

Application:
Very well suited for sealing the openings of vacuum bags (film to film). Permanently glues, films can only be removed mechanically.

Good adhesion to GRP, aluminum, steel, wood, other plastics incl. PE.

Pre- and post-processing of molds :
To facilitate the removal of the sealing strip from the edge of the mold, we recommend that the mold be treated beforehand with a release agent. Small residues of sealing tape on the mold can be removed with a cloth and acetone.
