Technical Details & Test Data
- Performance
For SMC, BMC, Hand Lay-Up, Epoxy and Polyurethane Applications:
MoldX A400 is Huber’s highest performing optimized ATH grade. It is engineered to impart outstanding fire retardance and smoke suppression in fiberglass reinforced SMC without halogen additives. Formulations have better mechanical properties because less MoldX A400 is needed to pass the same flame retardant certifications that would be required of competitive ATH grades.
Above is the rate of heat release and of smoke production for cured composite panels made via the sheet molding process with the ATH loading level at 350 phr. The panels were 0.100 inches thick. MoldX® A400 optimized ATH easily outperforms competitive ATH products in the critical areas of flammability and smoke suppression.
