Fire collars are fire stopping materials used to prevent the spread of fire. They are typically installed between components such as walls, floors, and beams inside buildings to prevent the spread of fire from one area to another. Fire collars, also known as passive fire protection materials, do not require additional firefighting equipment or systems to control the spread of fire; instead, they resist fires through their own physical or chemical properties. Their working principle mainly involves absorbing heat and providing insulation to slow down the spread of fire. Fire collars are important fire stopping materials that can effectively reduce the damage caused by fires.

The quality of fire stopping products depends on the manufacturer's quality control and production processes, and authoritative or certifying bodies also provide certification for these products. For example, UL (Underwriters Laboratories) is a globally renowned independent safety science company that offers various safety testing and certification services. Products certified by UL typically come with high-quality assurance.

To ensure the quality of our fire stopping products, Huai'an Shengchang Chemical Materials Co., Ltd. uses high-quality raw materials and strict manufacturing processes to guarantee product quality. We are the first domestic enterprise to obtain UL1479 certification for fire stopping materials.

In the following tests, Huai'an Shengchang's fire collars and fire stopping materials have passed the following examinations:

1. Fire resistance test: Testing the material's fire resistance at high temperatures, such as fire endurance and fire resistance time.
2. Heat insulation performance test: Testing the material's heat insulation performance at high temperatures, such as thermal insulation index and coefficient.
3. Combustion toxicity test: Testing the material's toxicity during combustion, such as harmful gases and smoke produced during combustion.
4. Mechanical performance test: Testing the material's mechanical performance at high temperatures, such as tensile strength and compressive strength.
5. Chemical performance test: Testing the material's chemical performance at high temperatures, such as corrosion resistance and acid-alkali resistance.

Fire collars are important fire stopping materials. If a fire collar fails, the fire may spread, leading to an expanded fire and more serious consequences.

Huai'an Shengchang is an ISO9001 quality system enterprise, strictly controlling product quality through the following measures:

1. Quality control of raw materials: The quality of raw materials directly impacts product quality. Shengchang selects high-quality raw materials and subjects them to strict quality control.

2. Control of production processes: Production processes are a decisive factor in product quality. When producing fire collars and fire stopping products, Shengchang adopts strict processes and quality control measures to ensure product quality.

3. Testing and inspection: During the production process, products undergo regular testing and inspection, with strict batch management, to ensure product quality meets requirements.

4. Personnel training and management: Producing fire stopping products requires a professional team. Shengchang's staff undergo rigorous training and possess relevant knowledge and skills. Additionally, Shengchang has established strict management systems to ensure smooth production processes.

Through these controls, the quality of fire stopping products is effectively improved, ensuring product safety performance.
