Product details and specifications

Product Features

High air permeability (DIN EN ISO 9237): ≥ 2360 L/m²s
Strong adhesive ensures permanent bonding even at high stress
Thick PET-fleece prevents PU-foam from oozing out during infusion process
Reduces cleaning and rework

Application Fields

Expanding PU-foams are often used to reduce NVH (noise, vibration, harshness) and provide additional stiffness by local reinforcement of body structures for crash and energy management.
tesa® 54321 venting tape prevents squeezing out of the PU-foam during the infusion and foaming process by allowing air flow through the non-coated fleece backing and thereby avoiding excess pressure.
