1. Product Overview
tesa® 4983 is an ultra-thin, transparent double-sided PET filmic tape with a tackified acrylic adhesive. With a total thickness of just 30 µm, it offers reliable adhesion to smooth surfaces relative to its thin profile. The tape provides excellent resistance against demanding environmental factors such as UV, humidity, and chemicals, while maintaining good converting performance. It is particularly suited for thin film and electronics applications where minimal adhesive thickness is required.
2. Applications
Lamination of cushioning materials to LCDs
Fixing of reflection foil to LCD frames
Splicing of thin plastic films
Dielectric bus bar mounting in thin film solar modules
