Material Notes:

Molecular Formula: C7H9O3PCas No.: 61451-78-3Application: HMPPA is a bifunctional copolymerisable phosphorous flame retardant monomer, which can be polycondesated with ethylene glycol and terephthalate to form flame retardant PET, and renders the alternated PET and the resulting plastic and fibers have good fire-resistance properties. The spinning property of the PET is fairly good as the HMPPA was used. It is readily soluble in water.Information Provided by Oceanchem Group
