Development of a new type of phosphorus-based halogen-free flame retardant to promote flame retardant upgrades

Recently, a new type of high-performance phosphorus-based halogen-free flame retardant has been successfully developed. This flame retardant exhibits excellent application effects in plastic products, providing strong support for the flame retardant upgrade of the plastics industry.

As a material widely used in various fields, the flame retardant properties of plastics have always been a key concern in the industry. Traditional halogen-containing flame retardants, while having good flame retardant effects, release toxic and harmful gases during combustion, posing a serious threat to the environment and human health. The newly developed phosphorus-based halogen-free flame retardant uses phosphorus as the main flame retardant component. During combustion, it mainly achieves flame retardancy by forming a carbon layer to block the transfer of heat and oxygen, and does not produce toxic and harmful gases during combustion, meeting environmental protection requirements.

In the process of plastic production and processing, this new type of phosphorus-based halogen-free flame retardant is added to the plastic raw materials in a certain proportion. After mixing, melting, and molding, plastic products with good flame retardant properties can be produced. Experimental data show that the oxygen index of plastic samples with this flame retardant added has increased from about 20% to over 30%, reaching the flame-retardant level. At the same time, this flame retardant can also give plastic products good antioxidant and stability properties, and is not prone to aging and performance degradation in high-temperature environments, extending the service life of plastic products.

The successful development of this new type of phosphorus-based halogen-free flame retardant not only solves the environmental problems of traditional halogen-containing flame retardants but also improves the comprehensive performance of plastic products. Currently, this flame retardant has been trial-used in the production of some plastic pipes, plastic films, and other products, and the market feedback has been good. Industry insiders say that with the further promotion and application of this flame retardant, it will promote the plastics industry to develop in a more environmentally friendly and safer direction.
