Abstract

Flame retardant compositions containing an inorganic flame retardant, such as aluminum trihydrate or magnesium hydroxide, and a flame retardant synergist containing hydrotalcite and clay at a weight ratio of hydrotalcite:clay ranging from 1:1 to 100:1, are disclosed. These flame retardant compositions can be used to produce polymer formulations with a unique balance of flame retardant, mechanical, and rheological properties.
