Low-smoke halogen-free flame-retardant polyolefin cable compound is composed of polyolefin blend resin plus flame-retardant filler such as aluminum hydroxide, magnesium hydroxide, and some antioxidants that can improve heat resistance. Sometimes, to reduce the amount of smoke generated during combustion, some smoke inhibitors, such as vanadium, nickel, molybdenum, iron, silicon, and nitrogen compounds are added. Flame…
Fine ATH has the three functions of flame retardancy, smoke suppression, and filling. So it is widely used in HFFR cable compounds. It has no secondary pollution during combustion, has good thermal stability, is non-toxic, has no corrosive gas, and good flame-retardant effect. It has the advantages of being a flame retardant and filler in…
Aluminum Hydroxide, also known as Aluminum Trihydrate (ATH) is an inorganic white fine crystal, non-hygroscopic powder. Its solubility in water and organic solvents is very low. By volume, ATH is the largest flame retardant (FR) used in various end applications. The working principle is based on the thermal decomposition of aluminum hydroxide into aluminum oxide…
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…
