tesa 58374

tesa 58374

is a transparent 100µm double-sided flame retardant PET tape. This tape has especially been developed for power battery demanding mounting, lamination and converting application with flame retardant property as an added value. Due to its non-flammable property it is particularly designed to meet power battery automobile requirement.

Product Features

  • Flame retardant UL94 VTM-0 equivalent

  • Excellent initial bonding to polar substrate (Steel, Al, etc)

  • Good reliability performance

  • Good die-cutting ability for converting process

  • Halogen-free

Application Fields

  •  Mounting in power battery olamination application required additional flame retardant property.
