Product introduction:
N-35B is a new type of highly efficient flame retardant masterbatch, the main effective material is a reactive P, N, Br composite flame retardant. The product is mainly designed for PP flame retardant modified use
With the traditional brominated flame retardants (tetrabromobisphenol A, decabromodiphenyl oxide, four eight bromo ether and eight bromo ether, double S TBC) compared to add less, good flame retardant effect, do not need to add three oxidation two antimony (low bromine content in modified good products almost no halogen requirements). At the same time the flame retardant also has excellent thermal processing stability, no precipitation, water resistance, light aging, non-toxic, and color masterbatch and other additives have side reaction characteristics.
The products can be directly used in injection molding, extrusion and other processes.
