Product Description

Brief  introduction

2,2-Bis(bromomethyl)propane-1,3-diol is a reactive flame retardant used in polymer

materials such as rigid ammonia foams, resins, and coatings.It is characterized by high

flame retardancy, light stability and transparency.

♦ Application

Its high bromine content and easy combination with polyurethane make it

particularly suitable for use in rigidpolyurethane foams. It is also increasingly

used in free-CFC foam systems to increase its flame retardant capability rating.
