Tesa 4541 - Conformable adhesive fabric tape 50 mm x 50 m (brown, uncoated fabric)
Tesa 4541 is a high-performance, uncoated cloth tape made with a 145-mesh rayon backing and a natural rubber adhesive . Available in a 50 mm x 50 m brown format, it is notable for its high tear resistance , excellent conformability , and very good adhesion, even on rough or slightly oily surfaces . Its matte surface is writable , facilitating marking and identification in the field.
With a total thickness of 270 µm , a tensile strength of 90 N/cm² , an elongation of 16% , and an adhesion to steel of 3.6 N/cm² , it offers a robust technical balance for sealing, fixing, bundling, cable wrapping, edge protection, and reinforcement . Furthermore, it incorporates 87% bio-based carbon (according to EN 16640) and withstands temperatures up to 130 °C for 30 minutes under controlled conditions.
