In the practice of using antimony trioxide (Sb₂O₃) for plastic flame retardancy, "uneven dispersion" is the primary process challenge that leads to fluctuations in flame retardant efficiency, deterioration of material mechanical properties, and appearance defects in products.

In the field of flame retardant science, antimony trioxide (Sb ₂ O3) holds a unique and classic position. It is not a strong flame retardant in itself, but when coexisting with halogen compounds, it can exhibit astonishing synergistic effects, increasing the overall flame retardant efficiency several times.

In the selection of halogen-free flame retardants, aluminum hypophosphite (AHP) is not a "master key", and its excellent performance is highly dependent on the "chemical dialogue" with the polymer matrix.

Zinc Borate has emerged as one of the most reliable and eco-friendly flame retardants for polymers and PVC. This article explores its chemical properties, benefits, industrial applications, and why it is preferred over other halogen-free flame retardants. With growing environmental regulations, Zinc Borate offers a perfect balance between performance and sustainability.

Aluminum hypophosphite (AHP) is a high-performance halogen-free flame retardant, and its long-term storage stability is an important prerequisite for ensuring consistent quality of end products. The core issue that the industry is generally concerned about is whether it absorbs moisture?

In the halogen-free flame retardant process of engineering plastics, a core "performance game" question is: does the introduction of aluminum hypophosphite (AHP) necessarily come at the cost of sacrificing mechanical properties?
