Aluminum hydroxide is used as a flame retardant in thermoplastics. 1. Application in epoxy resin In epoxy resin, it has a good flame retardant effect. The dosage is 40%~60%. The oxygen index is twice as high as that of unfilled epoxy resin. At the same time, it also enhances the arc resistance. The epoxy resin…
Due to the strong polarity of magnesium hydroxide, the surface of the particles is positively charged, which is easy to form secondary agglomerations, and its hydrophilicity makes the dried product still contain water. Adding directly to the polymer is not conducive to dispersion in the polymer material, and it is easy to produce gaps with…
Magnesium Hydroxide is a kind of eco-friendly inorganic halogen-free flame retardant. It is widely used in the plastic and rubber industry. When magnesium hydroxide is heated (340-490 degrees), it decomposes and absorbs the heat on the surface of the combustible to be flame-retardant; at the same time, it releases a large amount of water to…
Precipitated magnesium hydroxide has the advantages of high purity, good fluidity, ultra-fine particle size, and good thermal stability. It is non-volatile, does not generate toxic gases, and does not corrode processing equipment; Precipitated magnesium hydroxide, soluble in strong acid and ammonium salt solution, insoluble in water, added to the system has good dispersibility and nano-activity;…
