Product Description
KERAFIX® Flexpress 100 is a flexible, intumescent material on the
basis of expandable graphite, which expands with high pressure when
heat is applied.
Special feature: early start of reaction at approximately 140 °C.

Application Areas
■ Fire protection doors of wood, steel or aluminium
■ Glazing, facades
■ Safety storage cabinets, control cabinets
■ In drywall construction: inspection flaps, separating wall and floor constructions
■ Component joints, heat insulation elements
■ Fire protection flaps
