Products Usage
Aluminum hydroxide has many uses in medicine and industry. In medicine, it is often used as an antacid to treat digestive disorders such as peptic ulcers and acid reflux. In addition, it is also used as an adjuvant in vaccines to help enhance immune effects. Industrially, it is used as a filler or additive in the manufacture of products such as plastics, rubber, glass and building materials. In addition, due to its hygroscopicity and fire-retardant properties, it can also be used to make fire-retardant materials and some cosmetics.
Package And Storage
Packing:25/50/1000kgs/bag or as customer’s request.
Storage:Preserve in well-closed, light-resistant and airtight containers.
Conditions for safe storage, including any incompatibilities
Stored in a dry, clean, well-ventilated environment, away from fire sources and flammable substances. It is best to store in sealed containers away from strong acids, alkalis and other chemicals to avoid unnecessary chemical reactions. Also, take care to avoid confusion and place clear labels on storage containers to ensure accuracy and safety during use.
