BlackBox Insulation layer

Product Description

Flamebor BlackBox specialized developed to provide high temperature thermal protection for data recorder (commonly known as black box) in aircrafts, automobiles, ships and high-speed trains, is a thermal protection layer for data recorders to keep the memory board safe during post-accident fires.

Mainly made from a mixture of fumed silica, fiber reinforced materials and other additives, with strong thermal protection performance which can maintain a safety protection effect at a temperature of 1100℃ for at least 1 hour. Products can also be customized to meet the requirements according to the internal and external temperature parameters as well as the internal shape, making a match shape.

Flamebor BlackBox offers 4 thermal protection products series EDR, FDR, CVR and VDR for automotive, aircraft and voyage data recorders.
