ATH and MDH in elastomers
Elastomers can tolerate ATH or MDH loadings of 60% or somewhat higher without loss of useful properties although hardness is obviously increased. ATH is substantially less costly but limits processing temperatures to below about 200–220 °C. A combination of roughly equal amounts of ATH and MDH will often be found more effective in flame retardancy than …
