Brominated flame retardants dominated the market for decades due to their high flame retardant efficiency and cost-effectiveness. However, under environmental pressure, they are developing towards higher molecular weight and reactive formulations.

Inorganic flame retardants are a type of flame retardant material mainly composed of halogen-free compounds. They exert their flame retardant effect mainly through mechanisms such as heat absorption decomposition, dilution of oxygen, promotion of char formation, and formation of physical barriers.

Inorganic flame retardants and organic flame retardants are not in opposition but rather complementary and coexisting technical routes. In today's environment where environmental regulations are becoming stricter and performance requirements are increasing, it is increasingly difficult for a single component to meet complex demands. Synergistic compounding and systematic design are becoming the mainstream direction of flame retardant technology.

As agents that change the nature of interfaces, surfactants can considerably impact the characteristics of pore structures in dried powder products by altering particle interactions and their spatial arrangement. This article comprehensively investigates how surfactants affect, control, and are really useful in modifying the pore distribution patterns of dried powder samples, while also discussing supporting experimental data.

To minimize the van der Waals effect between powders, the use of sterically hindered dispersants (e.g. polymers or graft copolymers) is a very good choice. They basically interrupt the intermolecular pulling by forming a physical barrier on the particle surface. The application will vary according to the dispersion medium (water or organic solvent) and the powder characteristics.

For cross-material bonding (e.g., stone + plastic) → coupling agents For altering the bulk structure (e.g., from linear to network) → cross-linking agents For preventing particle sedimentation (e.g., pigment anti-settling agents) → dispersants

In the paint industry, there's a saying: "A large bucket of paint, half a bucket of minerals!" While it may sound exaggerated, it reveals the core role of non-metallic minerals in paints.
