Product Description

→Expandable Graphite:

Can be expanded graphite sheet expansion characteristics different from other kinds of expansion agent, heated to a certain temperature, due to absorption in interlayer matrix compound decomposition, began to swell, expansible graphite as starting expansion temperature, expansion completely in 1000 °C, the maximum volume. Inflation can reach above 200 times -300 times of the initial volume. After expansion of graphite is called expanded graphite or graphite worms, the original scaly into low density worm-like, formed a very good insulation blanket. Expanded graphite is a carbon source in the inflation system, and thermal barrier, can effective heat insulation, with in the fire heat release rate is low, the quality loss is small, the characteristics of the produced less smoke.
