Techmer PM
Kaan Serpersu, Techmer PM, presented tests of the mineral PIN FR magnesium hydroxide in polyethylenes and polypropylene. He showed that different grades (particles size, shape, coatings, etc) impacted fire retardant performance and polymer mechanical properties differently.
Organic and inorganic synergists enabled to reduce loadings of the mineral FR and still achieve UL 94-V0 (at 1.5 mm) and also improve mechanical properties. He underlined the effectiveness of these magnesium hydroxide based PIN FR systems in reducing smoke emissions (smoke density half that of halogenated systems).
