Ethylenebistetrabromophthalimide, FR-93W

Brief Description
Ethylene bis(tetrabromo phthalimide) (FR-93W)
Equivalent Brand Saytex BT-93W
Molecular Formula C18H4O4N2Br8
Molecular Weight 951.5
CAS No. 32588-76-4
Chemical Name 1,2-Bis(tetrabromophthalimido) ethane
CBNumber CB7401259

Features and Applications
1. The ethylene bis(tetrabromo phthalimide) has outstanding thermal stability and ultraviolet stability, which allows the brominated flame retardant to be applied in such engineering resins as ABS, ABS/PC, PE, and some others.


2. With white color, our ethylene bis(tetrabromo phthalimide) can be added to the substance that is sensitive to color. Its thermal stability makes it a great plastics additive for distinct engineering resins, such as polyester and polyamide (PA).


3. Owing to impermeability property, the flame retardant chemical can be used in some occasions that have a high demand for heat-sealing properties, such as polyolefin film. Due to superior wet electrical property, 1,2-Bis(tetrabromophthalimido) ethane can also be used as an ideal fire retardant of wires and cables.
