Phosphorus-based halogen-free flame retardants used in PVC products promote green development of the industry

PVC products are widely used in construction, packaging, electronics, and other fields due to their excellent properties, while the application of phosphorus-based halogen-free flame retardants has injected new impetus into the development of PVC products.

Traditional flame-retardant PVC products mostly use chlorine-containing flame retardants, which produce a large amount of toxic and harmful gases during combustion and do not meet environmental protection requirements. The emergence of phosphorus-based halogen-free flame retardants provides an environmentally friendly solution for flame-retardant PVC products. When added to PVC raw materials, and processed through extrusion, injection molding, etc., the resulting PVC products exhibit good flame retardancy, with an oxygen index reaching 28% or higher.

In building materials such as PVC pipes and sheets, PVC products containing phosphorus-based halogen-free flame retardants meet building fire safety requirements and do not release toxic substances during use, posing no harm to human health or the environment. In electronic and electrical PVC cables, the application of this flame retardant gives the cables good flame retardancy and electrical insulation performance, ensuring the safe operation of electronic and electrical equipment.

The application of phosphorus-based halogen-free flame retardants in PVC products not only improves the safety performance of PVC products but also promotes the development of the PVC industry towards a green and environmentally friendly direction, in line with the requirements of sustainable development.
