Different with many flameproof stuffings, aluminum hydroxide micropowder don't produce toxic and corrosive gas when heated to decompose, moreover, absorb heat and release water vapour to make products resistant to flame and self- extingushing. Therefore, adding this product into plastic, rubber and other high-grade materials can bring products good flame resistance and smoke abatement effect, and improve the resistant to creepage, electric arc and abrasion.
