AI Overview
Halogen-free preservatives are safer, environmentally friendly alternatives to halogenated compounds (like chlorine or bromine), widely used in electronics, construction, and consumer goods. They include phosphorus-nitrogen compounds and inorganic hydroxides (e.g., Aluminum Hydroxide, Magnesium Hydroxide) that reduce fire risk by releasing water vapor and forming protective char, producing less smoke and no toxic gases.
