Cloth tape is used to cover gaps and joints during injection to prevent the PU foam from squeezing out.

Gap Covering

Covering all gaps and joints prevents the PU foam from squeezing out during injection. Cloth-based tapes fit the contours of small corners best.



During foam injection, there is a risk that the PU foam could squeeze out of small gaps and joints. To avoid this, a tape that bonds to the PU foam should be used to cover all gaps and joints. In small corners and joints, the best solution is to use cloth tape, as this fits the shape more easily.

The tape used should have a high adhesion value. The backing should bond to the PU foam and it should be easy to unwind and hand tearable.
