fire retardant film, known as AT-FR. The most unique aspect of this NASA tested and approved AT-FR is that not only is the plastic film a clean halogen-free fire retardant (FR) polyethylene film, but it also dissipates static charges or arcing. Isn’t that smart, not only to prevent fires after ignition, but also aiding as a barrier in preventing fire from igniting in the first place. Being static dissipative, AT-FR is great for keeping electronic devices safe from electrostatic damage (ESD).
