Innovative application of brucite powder in highly flame-retardant PVC sheathing materials

In-depth discussion of the role of brucite powder as a key halogen-free flame retardant in improving the flame retardant performance, thermal stability and mechanical properties of PVC sheath materials, and its importance in the development of environmentally friendly wire and cable materials.

In the continuous innovation of wire and cable materials, highly flame-retardant PVC sheathing materials are favored for their excellent safety performance. Brucite powder, as an efficient halogen-free flame retardant, plays a vital role in product development in this field.

1. Brucite powder improves flame retardant properties. The addition of brucite powder can significantly improve the flame retardant properties of PVC materials. During the combustion process, brucite powder absorbs heat and releases water vapor, effectively reducing the burning speed and smoke production.

2. Enhance thermal stability Brucite powder helps to improve the thermal stability of PVC materials and prevent material decomposition at high temperatures, thus improving the safety and reliability of wires and cables.

3. Improve mechanical properties Surface-modified brucite powder can improve the elongation at break and wear resistance of PVC materials and extend the service life of cable sheaths.

4. Synergistic flame retardant system Brucite powder forms a synergistic system with other flame retardants such as aluminum hydroxide and zinc borate to further enhance the flame retardant effect of PVC sheathing materials and meet strict safety standards.

5. Development of environmentally friendly materials The environmentally friendly properties of brucite powder give it a place in halogen-free flame retardants. It does not produce toxic substances during the combustion process and meets modern environmental protection requirements.

6. Product performance testing and optimization Through systematic performance testing and production process optimization, ensure that the brucite powder is evenly dispersed in the PVC sheathing material to achieve high-performance wire and cable materials.

7. Market application prospects: Highly flame-retardant PVC sheathing material has broad market application prospects in the field of cable and wire manufacturing due to its excellent performance and environmental protection characteristics.

As a key additive for highly flame-retardant PVC sheathing materials, brucite powder not only improves the flame-retardant performance and thermal stability of the material, but also improves its mechanical properties while meeting environmental protection requirements. With the increasing global emphasis on environmental protection and safety performance, the application of brucite powder in the field of wire and cable materials will continue to expand.
