At present, a polymer material, as a representative of the fine chemical industry rapid development, promote the additives research and development process. Magnesium hydroxide flame retardant agent has green environmental protection low cost advantages, received more and more attention. Many countries use magnesium hydroxide as a name retardant instead of halogenated name retardant. Magnesium hydroxide has low fire retardant efficiency, it can achieve flame-retardant effect under large filling volume and then seriously deteriorate mechanical and processing properties of materials. In order to improve mechanical property of materials, and we must modify the surface properties of magnesium hydroxide. There have been researches about magnesium hydroxide surface modification, which normally applied surfactants or coupling agents as surface modification instead of not macromolecular surface modifiers. Increasingly becoming the focus of flame retardants research at home and abroad, magnesium hydroxide as flame retardant additives is easy to reunite dispersion such poor compatibility. Therefore, it’s an important inquisitive task to improve the surface properties.
FR-Mg(OH) is a non-halogenated, high purity magnesium hydroxide powder for use as a flame retardant and smoke suppressant in plastic compounds for thermoplastic olefins, plastic building materials, select wire and cable applications, and plastic fillers and coatings.
FR-Mg(OH) offers the following attributes and benefits:
- Excellent flame retardancy and smoke suppression properties
- Thermally stable
- Cost effective replacement for Alumina Trihydrate (ATH)
- Thermally stable to 340°C, suitable for engineering plastic
- Lower hardness than ATH resulting in longer equipment life
- Low toxicity [LD50 (oral/rat) > 5,000 Mg/Kg]
- Non-corrosive as compared to halogen or phosphorous-containing compounds
