Fireproof seal strip is an important fireproofing material widely used in construction, industry, and other fields.

1. Material Properties

Fireproof Material Composition

Fireproof seal strip is typically based on special fireproof rubber or silicone. These materials inherently offer excellent flexibility and weather resistance. Fireproof rubber maintains good elasticity at room temperature, adapting to various installation locations. Silicone, on the other hand, has a wider temperature range and maintains stable performance in both high and low temperature environments.

Fireproof seal strip also incorporates flame retardants and other fireproofing ingredients. These flame retardants react chemically when exposed to high-temperature flames, preventing the spread of fire. For example, certain phosphorus- and nitrogen-containing flame retardants form a dense charcoal layer upon combustion, which isolates the air and inhibits further combustion.

2. Performance Advantages

Fireproof Performance

Fireproof seal strip offers excellent fireproofing capabilities. When a fire breaks out, it effectively prevents flames and heat from spreading through gaps such as door cracks for a limited period of time. Generally speaking, high-quality fireproof seal strip can ensure the fire-resistant integrity of the seal within the specified fire protection period, buying valuable time for evacuation and fire rescue operations.

Sealing Performance

In addition to fire protection, its sealing performance is also crucial. It fits tightly into the gaps between door frames, doors, and windows, preventing the infiltration of smoke and air. In daily use, it also provides sound insulation, heat insulation, and dust protection, enhancing the overall comfort of the building.

Durability

Thanks to its special formulation and processing, fireproof seal strip has excellent durability. It resists environmental factors such as UV rays, moisture, and abrasion, maintaining its fireproof and sealing properties over time.

3. Application Scenarios

In the construction industry, fireproof seal strip is widely used to seal fireproof doors, fireproof windows, ventilation ducts, and other facilities. It is an indispensable material for ensuring fire safety in various buildings, including industrial plants, warehouses, commercial buildings, and residential buildings. It is also used to seal specialized equipment, such as fireproof distribution cabinets.
