Hydrotalcite FG

Hydrotalcite FG by Akrochem is magnesium-aluminum hydroxy carbonate-based filler. It also functions as flame-retardant and smoke suppressant, as it can add the benefit of releasing water and internal decomposition at 300°C (higher than ATH, thus safer processing). It also functions as an inorganic stabilizer with halogenated systems.

• It exhibits non-toxic, non-corrosive and non-volatile properties.
• It is used as a lead replacement in halogenated polymers to scavenge acid by-products, which are detrimental to many polymeric processing and physical properties.
• It improves the color of EPDM by scavenging the acid chlorides leftover from the polymerization process.
• In most formulations, lead oxides will show slightly better water-swell behavior compared to hydrotalcite products.
• It is utilized as a lead oxide replacement to scavenge acidic by-products in halogenated polymers like CR, CSM, CPE, ECO, PVC, FKM, BIIR and CIIR. In addition, these antacids provide superior water-swell compared to magnesium oxides in all the elastomers.
• Hydrotalcite FG is suitable for electrical applications for their anti-tracking properties.
• It is also designed for compounds that could not be colored brightly due to lead content.
