摘要:
Magnesium oxide and a zinc salt are reacted with one another to form a magnesium zinc complex salt which is added to a halogen-containing plastic composition to serve as a smoke and/or fire retardant during combustion of the plastic. This magnesium-zinc complex salt is normally added along with an antimony compound but may be used alone if desired.
