Aluminum hypophosphite (ALPI), as an efficient phosphorus based halogen-free flame retardant, is widely used in engineering plastics. This article systematically evaluates the safety of aluminum phosphate from multiple dimensions.

With the tightening of global environmental regulations and the deepening of sustainable development concepts, halogen-free flame retardants have become the mainstream choice for flame retardant modification of polymer materials.

In the field of flame retardant materials science, zinc borate is highly favored due to its high efficiency and environmental friendliness. However, there are two major categories in the market: "anhydrous zinc borate" and "hydrated zinc borate", and their fundamental differences are far more than just whether they contain crystalline water.

Zinc borate has become an important choice for environmentally friendly inorganic flame retardants in the formulation design of flame retardant materials. However, faced with the two main hydration types on the market, zinc borate monohydrate (ZnO·B₂O₃·H₂O) and zinc borate 3.5hydrate (2ZnO·3B₂O₃·3.5H₂O), many engineers and procurement decision-makers are facing a dilemma in their choices.

Zinc borate, as an efficient and environmentally friendly inorganic flame retardant and multifunctional additive, has been widely used in plastics, rubber, coatings, textiles and other fields.

Among numerous variants of zinc borate, 3.5 Hydrated Zinc Borate (2ZnO·3B₂O₃·3.5H₂O) has become the most widely used and formulated variety in global polymer flame retardant systems, accounting for over 75% of the industrial zinc borate market share.
