Natural brucite powder: an environmentally friendly choice to improve the flame retardant properties of PP and ABS plastics

In the current context of increasingly stringent requirements for environmental protection and safety performance, natural brucite powder, as an environmentally friendly inorganic flame retardant, shows great potential in the modification of polymer materials. Especially in the application of polypropylene (PP) and acrylonitrile-butadiene-styrene copolymer (ABS) plastics, the addition of brucite powder not only improves the flame retardant properties of the materials, but also meets the thermal stability, mechanical requirements Comprehensive requirements for performance and processability.

Significant improvement in flame retardant performance

Natural brucite powder decomposes under high temperature conditions, producing water vapor to absorb heat and dilute combustible gases. At the same time, the generated magnesium oxide layer effectively isolates oxygen, significantly improves the limiting oxygen index (LOI) of PP and ABS plastics, and reduces combustion droplets. fell, improving the horizontal burning test level.

Optimized maintenance of mechanical properties

The application of surface treatment technology, such as TC-114, TSC coupling agent or stearic acid, improves the interfacial compatibility between brucite powder and plastic matrix, reduces stress concentration, and maintains or enhances the tensile strength and strength of composite materials. Impact strength.

Enhanced thermal stability

The addition of brucite powder increases the heat deformation temperature of PP and ABS plastics, enhances the thermal stability of the materials, and makes them more suitable for applications in high temperature environments.

Guarantee of processing performance

By selecting appropriate particle size and dispersion, and optimizing the processing technology, the processing fluidity of plastic composite materials is ensured, and problems such as melt fracture during processing are avoided.

Environmentally Friendly Advantages

Compared with traditional halogen flame retardants, natural brucite powder, as a flame retardant derived from natural minerals, has harmless decomposition products and is more environmentally friendly, in line with the materials industry's pursuit of sustainability and safety.

Significance of cost-effectiveness

As an abundant and low-cost resource, the application of natural brucite powder in flame-retardant PP and ABS plastics provides a cost-effective solution, especially where flame retardants are used on a large scale.

As a flame retardant for PP and ABS plastics, natural brucite powder not only effectively improves the flame retardant properties of the materials, but also maintains or improves other physical properties of the materials through reasonable modification methods, while meeting the requirements of environmental protection and cost-effectiveness. Double needs. As the demand for environmentally friendly flame retardant materials continues to grow, the application prospects of brucite powder will be broader.
