50µm/2 mil double sided PET flame retardant tape

Product description

tesa® 58372 is a translucent, double-sided PET tape equipped with flame retardant tackified acrylic adhesive.

The flame retardant acrylic adhesive gives this product unique anti-flaming property, and also a good bonding performance even after long-term storage conditions. Its ultra thinner PET backing offers excellent converting performance for purpose of  lamination. The white/red logo glassine liner ensures it can be easily released without adhesive residue.

Key features of tesa® 58372:
  • Thickness: 50µm/2 mil
  • Flame retardant per UL 94 VTM-0 level
  • Good bonding performance
  • High long-term reliability and aging resistance
  • Good handling performance in converting process
  • Conforming to RoHS, REACH
  • Halogen-free

Main applications

tesa® 58372 can be introduced for EV battery pack sealing when it laminated with foamto meet the flame retardant target for E-mobility market. It is also used for general mounting applications especially  in the EV battery system and the other environment in automotive industry when it comes with anti-flaming requirement.
