It is found that the inorganic reinforcement minerals improved the flame retardant properties and thermal stability of polymer nanocomposites depending on the amount of additives. The huntite/hydromagnesite and antimony trioxide effectively reduce the flammability of the ABS composites utilizing synergism by achieving UL94/V-0 classification.

Halogen-containing flame retardants act in the gas phase of a fire. When a polymer burns they decompose by generating free and highly reactive radicals in the gas phase which are responsible for the propagation of a fire. Then produced incomplete burned substances lead to an increase in smoke density which is more toxic and corrosive 12

Get PriceHuntiteInfogalactic the planetary knowledge core
The most common industrial use of huntite is as a natural mixture with hydromagnesite as a flame retardant or fire retardant additive for polymers. The heat of a fire will cause huntite to decompose releasing carbon dioxide into the flames. This helps to slow the spread of the fire.
