Fire resistant (in case of fire) expansion sealant strip

Introduction and application of fireproof (fire resistant) expansion sealing strips

Fire expansion sealing strips are mainly used between doors and frames of fire-resistant door and window products. When a room catches fire and the temperature reaches a certain value, they isolate the air circulation between two rooms and prevent the spread of flames. The application of this product has replaced the asbestos rope used for gaps in domestic fireproof doors and windows, and has been tested by the National Fixed Fire Extinguishing System and the Quality Supervision and Testing Center for Refractory Components. All indicators are qualified.

This product not only has excellent fire expansion performance, but also its good flexibility gives it excellent sealing and shock resistance performance. Meanwhile, due to the use of extrusion technology, flexible fireproof expansion sealing strips of various shapes and lengths can be made according to user requirements, providing convenience for user applications. The regular dimensions of this product are: 2mm x 15mm, 2mm x 20mm, 2mm x 25mm (can be specified by the customer). Fire strips can quickly expand and seal the gaps between doors and windows when heated, preventing smoke and heat from entering and ensuring personal safety.

The characteristics of fire expansion sealing strips:

1. The material treatment of the fireproof expansion sealing strip is exquisite, with high purity and a large expansion factor when exposed to fire.

2. After being subjected to fire, the fireproof expansion seal has a certain degree of stickiness and will not be carried away by flames, resulting in a good sealing effect.

3. The processing of fireproof expansion sealing strips is exquisite, with precise dimensions and complete specifications. They can be produced according to user requirements, reducing losses for users in production.

4. Passive fire protection (passive fire prevention): It has no extinguishing effect on its own. It is used in situations where a fire has already occurred to prevent the spread of the fire and achieve the goal of preventing loss of life and property.
