MDH and ATH in PA6

MDH and ATH flame retardants in PA6 are the main inorganic flame retardant used in PA6.

Magnesium hydroxide(MDH) and aluminum hydroxide(ATH) can have a good synergistic flame-retardant effect.

Magnesium hydroxide and aluminum hydroxide are compounded in a ratio of 3:1 as a flame retardant, and when used in glass fiber reinforced PA6, the tensile strength and bending strength of the material can be maintained very well. and the limiting oxygen index reaches 31.7 %.
