1. Product Overview
tesa® 4967 is a transparent double-sided PET filmic tape coated with a modified acrylic adhesive. It is designed for extremely high holding power, even at elevated temperatures, while maintaining strong converting performance due to its robust PET backing and reduced adhesive mass flow. The tape provides good adhesion to a variety of substrates, including low surface energy (LSE) materials, making it suitable for critical bonding applications across electronics, automotive, and furniture industries.

2. Applications

  • Mounting lenses in mobile phone housings

  • Fixing ABS plastic parts in the automotive sector

  • Mounting decorative profiles and mouldings in furniture production
