FIRE RETARDENT ALUMINUM COMPOSITE PANEL (B1)


FIRE RETARDENT ALUMINUM COMPOSITE PANEL (B1)

KT-A/B-FRPE is a non-combustible mineral filled core, with no halogen, low smoke and fume. It is used for FRACP consisting of two aluminum cover sheets and a noncombustible mineral filled core.

KT-A/B-FRPE was especially designed for flat die extrusion at low compression Screws or for calendar processing. The mineral used is brucite (natural magnesium Hydroxide) OR ATH: AL(OH)3. The compound allows melt temperatures of 130-280℃ at extrusion.

KT-A/B-FRPE has been designed to comply with standard of fire behavior as follows:
EN 13501-1:2007 (EU) B-s1, d0
BS 476, Part6/Part7 (UK) I≤12, i1,2,3 ≤6 and Class 1

Processing guide lines

Screws:

Most halogen free, low smoke materials have a melt viscosity higher than PE/PVC compounds. Such compounds require more power during processing, which leads to a rapid increase in melt temperature, as the screw speed increase.

KT-A/B-FRPE has been processed on a variety of screw designs, but for optimum output, the use of a low compression, low shear screw is recommended.

Processing Temperature:

The processing temperature of KT-A/B-FRPE is depending on what type of extruder is used, we could give detailed suggestion with your information on that.

Drying:

If material have been stored for an extended period, it may prove prudent to dry the material before extrusion. We would suggest a temperature of 80℃ for several hours in a desiccant hopper dryer would be adequate Vacuuming or bubble extinguishing agent are also suggested under usual occasions; During the vacuuming, the ratio between feeding quantity and extruding rate should be carefully adjusted, to prevent the flowing out of core material from vacuum outlet.
