Martinal® aluminum hydroxide specialties, either ground or finely precipitated, can be used as flame retardants in processes that require temperatures at or below 210°C. Their complex flame retardant mechanisms, which involve heat absorption, water vapor release, and char formation, make them invaluable in preventing and mitigating the impact of fires. AI generated definition based on: Handbook of Fillers (Fifth Edition), 2021 Dec 16, 2024 · Discover Apyral® 40 CD, a flame retardant with low oil absorption and excellent mechanical properties for cable, electronics, and construction applications. Download free datasheet!. ATH has found extensive applications across various industries. In comparision, aluminium hydroxide has a lower decomposition temperature than magnesium hydroxide, and therefore the latter is more stable at higher temperature23. The Aluminum trihydroxide is defined as a chemical compound with the formula Al (OH)3, consisting of 94-97% aluminum hydroxide, and is commonly used as a fire retardant and in various applications such as coatings, composites, and water treatment. Aluminium hydroxide (ATH) and magnesium hydroxide (MH) are both well-known fl ame-retardants for elastomers, thermosetting resins and thermoplastics free from halogens19-22. Understanding the science behind its action provides valuable insight into why this inorganic compound is so highly regarded in fire Overview of Aluminum Hydroxide Flame Retardants Among the broad spectrum of available options, aluminum hydroxide (Al (OH) 3, ATH) has emerged as a versatile and widely utilized flame retardant. Aluminum Hydroxide (ATH), chemically Al (OH)₃, is a widely-used flame retardant derived mainly from bauxite ore. ATH functions as both a flame retardant and smoke suppressant. The effectiveness of Aluminum Hydroxide (ATH) as a flame retardant is rooted in fundamental chemical and physical principles. The several phosphorous modified epoxy resin to ATH mass ratios were used to study the effect of ATH addition on epoxy. Jun 30, 2018 · A novel phosphorous containing flame retardant epoxy resin is synthesized by modifying the epoxy resin initially with phosphoric acid and further with aluminum hydroxide (ATH) to enhance the fire retardancy of the modified epoxy resin. It is used especially for telecommunication and data cables, but also for cables of household appliances as flame-retardants. 200 °C and above. ATH provides flame retardancy through Apr 24, 2018 · A series of novel aluminum phosphate ester (APEA) flame retardants were synthesized by the salification of cyclic phosphate ester acid (PEA) with different mass ratios of aluminum hydroxide (ATH) and thoroughly characterized by Fourier transform infrared (FTIR) spectroscopy and 1H nuclear magnetic resonance spectroscopy. Aug 28, 2023 · Two kinds of fillers, aluminum hydroxide (Al (OH) 3) and magnesium hydroxide (Mg (OH) 2) were used as fire retardant (FR) fillers to improve the flame-retardant behavior of an acrylic based coating. Aluminum hydroxide flame retardants are an essential pillar of fire safety across multiple industries. this reaction is endothermic and cools down the source of the fire. Aluminum Hydroxide, aluminum trihydrate or ATH, is an inorganic compound whose primary use other than aluminum metal production is as flame retardant filler for polymers. The PEA and APEAs were thoroughly mixed with melamine formaldehyde resin Jan 1, 2016 · The synergistic flame retardant effects between aluminum hydroxide (ATH) and halogen-free flame retardants in high density polyethylene (HDPE) composites used for geo-grid were characterized by carrying out limited oxygen index (LOI) test, UL94 vertical burn test, alcohol blow 1amp test and cone calorimeter. It can be used in many different applications – including coatings, wire and cable products, building and construction materials and solid surface applications. It suppresses flames effectively by releasing water vapor during decomposition, cooling the material, and reducing the availability of combustible gases. They are commonly used in different polymeric backbones for cable compounds. Jun 4, 2025 · Using an effective flame retardant can address these critical concerns. The fire residue structure of the composites was examined by means of digital camera Jun 4, 2025 · Aluminum Hydroxide (ATH), chemically Al (OH)₃, is a widely-used flame retardant derived mainly from bauxite ore.
