Precision die cuts for permanent hole covering of venting holes
tesa® 54321 is a thick PET-fleece with acrylic adhesive. This product is optimized for the automotive industry to covers venting holes.
The product is designed as a die cut, where the inner ring zone is adhesive free to generate the venting effect. The outer ring zone is coated with a high adhesion adhesive.
tesa® 54321 prevents the PU-foam from oozing out during the infusion process and allows the suppressed air to flow through the fleece backing to reduce cleaning and rework.
tesa® 54321 venting tape covers holes to avoid the squeezing out of the PU-foam during the infusion and foaming process, but to allow air flow and thereby avoid excess pressure.
Expanding PU-foams are often used to improve NVH (noise, vibration, harshness) and stiffness to provide local reinforcement to body structures for crash and energy management.
