Product Description

Flextrem 100 is a graphite based intumescent strip. It is a fibreless material and expands three-dimensionally during a fire, continuing to expand even at high temperatures (>900°C). Flextrem produces an extremely high expansion volume. Smaller quantities of the material are sufficient for certain constructions. The material also has very good water resistance qualities.
