Fire expansion sealing strip has the following characteristics:

1. When heated, it can expand rapidly and close the gaps between doors and Windows to prevent smoke and heat from entering and ensure personal safety.

2. Expansion temperature: the initial expansion temperature is 199℃, and the main expansion temperature is 347℃; The temperature rose to 980 degrees and remained for 30min without combustion or incineration.

3. Environmental resistance: The expansion ratio remains unchanged under the condition of 90 humidity for 120 days.

4, in a certain time (up to 120 minutes) to maintain good fire and smoke insulation performance.

5. Low reflection temperature, short reflection time, expansion multiple greater than or equal to 3 times the original thickness of the expansion body, 120℃ can produce significant foam pressure, fire and smoke performance combined to achieve heat insulation and noise isolation.

6, fire expansion seal as the "fire expansion of building materials" in the application of fire building components has been approved by the relevant regulations and building laws of Germany.

7. General dimensions of fire expansion seal strip: 2mm*20mm*1050mm, 2mm*15mm*1050mm, 2mm*10mm*1050 (customized according to customer requirements)
