Fire protection fabric

from Wikipedia, the free encyclopedia

A fire protection fabric is a textile that is supposed to protect components such as cables from fire. Nowadays, fire protection fabrics usually consist of open-meshed (grid-like) fiberglass fabrics with a foaming coating . In the past, asbestos fibers were also woven and used in fire protection.

Due to the chemical composition and texture, the coating of modern fabrics reacts in several stages, so that an operating temperature of up to approx. 100 ° C is possible. The fabric reacts at approx. 100 ° C by sticking and closes the pores from approx. 150 ° C before it begins to foam at around 200 ° C. In the event of deflagration and explosive combustion, the fabric also reacts like a shock with foaming. The foaming creates an insulating layer that protects the components behind it from overheating and fire for a certain period of time.

In contrast to conventional fire protection systems with a fire bulkhead , the fabric has the advantage that, due to the low mass per area of ​​around 1.7 kg / m², there is no major structural load to be taken into account. Due to the flexibility of the material, fire protection fabric is very suitable for the fire protection of cables and wires.

It is more of a niche application. This fire protection product is offered under the trade names Hapuflam and BC Brandschutz-Kabelbandage .
