Developed for use with polypropylene and TPV (thermoplastic vulcanisate) seals, Tesa has introduced its ACXplus 74508 Seal Line and ACXplus Black Line tapes to the automotive market. The company claims applications in the automotive sector include the mounting of window seals, water box seals, sunroof seals and obstacle detection systems (ODS).
The products are both based on a viscoelastic acrylic foam core and Seal Line offers an additional heat activated adhesive layer to the sealing side. Tesa says the advantages of using heat-activated tape for PP/EPDM/TPU based window seals and water box seals are that bonding is more secure and that the application process, which is more environmentally friendly as no primer is necessary, is also more efficient, increasing speeds to as much as 20 metres per minute.
