ICL > Products >  potassium Bromide Compacted

Chemical Name: Potassium Bromide Compacted

Formula: KBr

CAS Number: 7758-02-3

General & Use:
Potassium Bromide is used in combination with Copper complexes as heat stabilizer in Polyamide compounds, where high thermal stability during the product’s life cycle is needed. The main applications of such heat stabilized polyamides are in automotive under-the-hood parts and specialty fibers.
It is as well used in preparing photographic emulsions and developing solutions and in pharmaceutical preparations.
