Brucite powder composite flame retardant system: a new driving force for improving LDPE performance

Driven by advances in materials science, low-density polyethylene (LDPE) has found widespread use in multiple industries due to its superior lightweight and heat-resistant properties. However, the flammability of LDPE also raises concerns about its safety. In order to solve this problem, brucite powder, as an efficient inorganic flame retardant, is widely used in the flame retardant modification of LDPE due to its halogen-free, non-toxic, low-smoke and other properties. This article will explore how brucite powder and its composite flame retardant system can significantly improve the performance of LDPE and analyze its positive impact on material performance.

Flame retardant effect of brucite powder

The magnesium oxide produced by the decomposition of brucite powder when heated can form a heat-insulating carbon layer on the surface of the material, effectively slowing down the thermal decomposition rate and absorbing the heat generated by combustion. This process not only reduces the temperature of the material, but also reduces the heat release rate and smoke density during combustion, thereby significantly improving the flame retardant properties of LDPE.

Innovative applications of composite flame retardant systems

In order to further improve the flame retardant properties of LDPE, researchers developed a composite system of brucite powder and other flame retardants. These systems form a layer of organic flame retardant on the surface of brucite through physical or chemical methods, which not only improves its dispersion and compatibility in LDPE, but also enhances the overall flame retardant effect.

The positive impact of brucite powder on the properties of LDPE

Research shows that the addition of brucite powder and its composite system can significantly improve the flame retardant properties of LDPE. This modification not only improves the oxygen index and tensile strength of the material, but also improves the elongation at break, allowing LDPE to achieve higher safety performance while maintaining its original physical properties. In addition, the addition of brucite powder also improves the thermal stability of LDPE, effectively inhibits the cracking of the polyethylene main chain, and enhances the thermal stability of the composite material.

The development of brucite powder and its composite flame retardant system provides an efficient and environmentally friendly solution for the flame retardant modification of LDPE. This modification technology not only improves the flame retardant properties of LDPE, but also maintains the material's excellent processability and mechanical properties, meeting the market's demand for high-performance flame retardant materials. As the demand for environmentally friendly flame-retardant materials continues to grow, the application prospects of brucite powder and its composite system in LDPE will be broader, providing new possibilities for safer and more environmentally friendly material applications.
