Perkalite is an orgaanically modified clay based on magnesium- aluminum layered double hydroxydes(LDH), also referred to hydrotalcite. Upon compounding in polymers, Perkalite can be delaminated to nanoscale level, resulting in improved polymer properties such as thermo-mechanical, flame retardant, barrier and rheological properties.
