Regulators worldwide continue to update the requirements to increase the fire retardant and smoke suppressant performance of plastics and rubber compounds. Their goal is to improve the safety of trains, buses, roofing, office buildings and electrical equipment by insisting on parts that resist flame propagation, generate little smoke and are also safe to handle.
In order to meet these new regulations, compounders are looking to increase the loading of environmentally-friendly fire retardants and smoke suppressants such as Alumina Trihydrate (ATH) and Magnesium Hydroxide (MDH). But, it is not always easy to incorporate these polar ingredients which have hydroxyl functionality into non-polar thermoplastic resins and elastomers.
To allow faster incorporation and higher loadings, Huber offers a wide variety of high-performing ATH and MDH products with silane surface treatments. The surface treatment converts these hydrophic ingredients into non-polar functional pigments which mix in much more quickly and enable higher loadings for increased fire retardance.
