1 thought on “Application of aluminum hydroxide”
Nettie
Aluminum hydroxide is the maximum dosage and the most widely used inorganic flame retardant additive. Aluminum hydroxide can not only be flame retardant, but also prevent smoking, no drops, and no toxic gases. Therefore, it has obtained a widespread application, and the amount of usage is also increasing year by year. Scope of use: thermosetry plastic, thermoplastic plastic, synthetic rubber, coatings and building materials industries.
