The future oriented halogen-free, low smoke, high fluidity flame retardant materials, with the core goals of "zero halogen, low smoke toxicity, V-0 level flame retardant, high melt flow, mechanical stability, and full lifecycle environmental protection", have become the technological high ground and market demand of the global polymer materials industry.

High performance ultrafine magnesium hydroxide, represented by MDH-III-3, fundamentally overturns the dilemma of traditional inorganic flame retardants with "excessive filling, poor performance, and poor appearance" through its three core characteristics of submicron particle size, polymer flexible interface layer, and ultra-high purity.

Magnesium hydroxide (Mg(OH)₂) is increasingly widely used as an environmentally friendly inorganic flame retardant in polymers such as polypropylene, polyethylene, and nylon. However, its dispersion uniformity in the plastic matrix directly affects the flame retardant efficiency, mechanical properties, and processing stability of the composite material. This article systematically explores professional solutions to enhance the dispersibility of magnesium hydroxide from the perspectives of interface compatibility, agglomeration mechanism, and processing kinetics.

The European Union's "Restriction of Hazardous Substances in Electrical and Electronic Equipment Directive" (RoHS 2.0, 2011/65/EU and its amendments) sets clear restrictions and compliance requirements for hazardous substances in wire and cable materials. This article systematically analyzes the technical boundaries and exemption clauses for the ten restricted substances (lead, cadmium, hexavalent chromium, mercury, polybrominated biphenyls, polybrominated diphenyl ethers, and four phthalates) under RoHS 2.0 for cable materials.

In the field of halogen-free flame-retardant cable materials, magnesium hydroxide (MDH) and aluminum hydroxide (ATH) are the two mainstream filling flame retardants, and their selection directly affects the flame retardant grade, processing performance, long-term reliability, and cost of the cable. This article is based on the thermal decomposition mechanism, crystal morphology, and surface characteristics.

Antimony trioxide (Sb₂O₃) is the most widely used and cost-effective inorganic synergistic flame retardant in the global flame retardant material system. Relying on the antimony halogen synergistic flame retardant mechanism, it is indispensable in fields such as plastics, rubber, fibers, coatings, electronics and electrical equipment, wires and cables, and building materials. This article is based on the general calculation logic of the international flame retardant industry, and systematically explains the amount of Sb₂O₃ added.
