Single-sided transparent matt PU film for automotive slush skin applications

Product description

tesa® 50340 is a matt transparent single-sided tape consisting of a highly conformable PU backing and an age resistant acrylic adhesive, covered by a transparent PET liner. tesa® 50340 is specifically designed to seal the seam holes of automotive slush skins during the process of back foaming of cushioned dashboard surfaces. tesa® 50340 is a pressure sensitive tape and does not require any thermal activation and allows sealing without effecting the A-surface appearance.
