tesa® 4129

PET Multipurpose Tape

Product description

tesa® 4129 is a transparent, single-sided tape featuring a polyester backing with an acrylic adhesive. tesa® 4129 is used for various applications, especially for splicing of filmic materials, litho mounting or edge protection and reinforcement. The thin high-temperature tape conforms well around irregular shapes and its acrylic adhesive system combines good initial tack with high shear strength and provides a high short-term temperature resistance of 200°C. tesa® 4129 is resistant to humidity and most chemicals.  

  • High resistance to humidity and chemicals
  • Thin tape design for good conformability
  • High short-term temperature resistance (200°C)

Main applications

  • tesa® 4129 is recommended for splicing of filmic materials, e.g. photographic negatives
