tesa® 51903

Double-sided self-adhesive tape without liner

Product description

tesa® 51903 is a double-sided adhesive tape, consisting of a PVC-film without liner.

The adhesive on both sides is exactly balanced, so that tesa® 51903 can be unwound easily, even after long periods in storage.

Application Fields

  • Mounting of light weight parts
  • Splicing of various materials such as plastic, metal foils, paper and cardboards.
  • The acrylic-mass system has different adhesion values on each side. tesa® 51093 is therefore especially suited as closure system even for thin film bags.
tesa® 51903 is also used for mounting in the lithography industry.
