Application

Aluminium Hydroxide for Construction Materials is a highly versatile and widely used inorganic additive flame retardant. It not only provides excellent resistance to fire, but also effectively prevents the release of smoke, toxic gases, and dripping. As a result, it finds extensive application in various sectors such as Hot Solidifying and Moulding Plastic, Synthetic Rubber, Coating, Aluminum Composite Panel, Wire and Cable, Electrical Insulator, FRP profiles, Pultruded & Molded FRP Grating, Ceramic Rolling Rods, Solid Surfaces (Artificial Marble and Acrylic Sheets), Mobile Phone Circuit Board, LED Lamps, Paints, and more.

Package, Transportation, and Storage

The product is carefully packaged to ensure its integrity and safety during transportation. It is enclosed in an internal plastic bag with a knitted exterior, which is further covered with a protective film. The net weight of each package is available in options of 25kg, or 40kg.  It should be shielded from moisture, rainfall, and any potential damage to the packaging. For optimal storage conditions, it is recommended to store the product in a dry warehouse with adequate ventilation. This will help maintain its quality and effectiveness over time.
