magnesium hydroxide

Flame-retardant polymer composites based on homo- or copolymers of propylene as the matrix polymer and dispersed magnesium hydroxide, surface-modified by polyperoxides, as the filler have been obtained and characterized. The influence of the polyperoxide nature and the content of peroxide groups immobilized at the filler surface onto the mechanical and rheological properties as well as flame retardancy of composites have been studied.
