Expansion fireproof sealing strip is a key material used for fireproof isolation, widely used in fireproof sealing of doors, windows, pipelines, cable penetrations and other parts in industries such as construction, power, and ships. The following are the five main selling points of expansion fireproof sealing strips:

### 1. **Efficient fire resistance performance**
-Under high temperature or fire conditions, the expansion fireproof sealing strip can quickly expand, fill gaps, and effectively prevent the spread of flames and high-temperature smoke.
-Compliant with international fire safety standards such as UL, BS, EN, etc., with a fire resistance time of several hours, ensuring effective fire isolation.

### 2. **Excellent sealing performance**
-The expansion fireproof sealing strip is soft and elastic at room temperature, which can tightly fit the gaps and prevent air, smoke, and water from penetrating.
-In the event of a fire, the expanded sealing strip can completely fill the gap and form an effective fire barrier.

### 3. **Strong durability**
-Made of high-performance refractory materials, it has excellent aging resistance and corrosion resistance, and can be used stably in various environments for a long time.
-Strong weather resistance, adaptable to extreme temperature and humidity changes, and long service life.

### 4. **Easy to install**
-The design is lightweight and flexible, and the installation process is simple and fast. It can be directly pasted or embedded into the parts that need to be sealed.
-We can customize the size and shape according to customer needs to meet the installation requirements of different scenarios.

### 5. **Environmental Protection and Safety**
-Made of environmentally friendly materials, non-toxic and harmless, in compliance with environmental standards.
-In the event of a fire, it can effectively reduce the release of toxic smoke, protect personnel safety and the environment.

###Summary
Expansion fireproof sealing strips have become an ideal choice for building and industrial fire isolation due to their efficient fire resistance, excellent sealing effect, durability, easy installation, and environmental safety. Whether it is doors, windows, pipelines, or cable penetrations through walls, it can provide reliable fire sealing solutions to ensure fire isolation and personnel safety.
