Ingredients: hydrated sodium silicate, glass, additives, epoxy coating

Fire and smoke seal swell rapidly expands when heated in a closed door, window gaps and prevent smoke and heat fleeing, to ensure personal safety.

Expansion temperature: initial expansion temperature 199 ℃, the main expansion temperature 347 ℃; the temperature rose to 980 ℃ and maintain 30min, no burning, no ash;

Heat and flame and its performance: the left door seal is installed, and on the right side of the gap at no significant leakage of smoke, within a certain time (up to 120 minutes) to maintain good performance of the fire and the smoke. Low reaction temperature, short reaction time to begin to swell, linear expansion multiples larger than the original thickness of the expansion of three times; 120 ° C can produce significant bubble pressure, fire and smoke performance combined reach insulation and noise isolation, the fire protection board as a "fire expansion of construction materials" used in fireproof construction elements in Germany has been approved by the relevant regulatory and construction law.

Resistance to environmental capacity: stand at room temperature, and humidity conditions 120 days 90 expansion rate unchanged.

Regular Size: 2mm * 20mm * 1050mm, 2mm * 15mm * 1050mm, 2mm * 10mm * 1050 (can be used with customer specified size).
