Perkalite® is a unique and versatile synthetic organoclay, developed by Akzo Nobel. The product is based on synthetically produced and organically modified layered double hydroxides (LDH). Upon compounding in polymers, Perkalite can be delaminated to nanoscale level, resulting in improved properties such as:
A unique feature of Perkalite is its higher temperature stability, compared to other commercially available organoclays based on montmorrilonite.
Due to the low addition levels needed, Perkalite offers cost effective solutions for numerous applications including:
Low Smoke Zero Halogen flame retardant compounds
With Perkalite the amount of mineral flame retardants in e.g. wire & cable and construction materials can be reduced, resulting in better mechanical properties, better processing and reaching more stringent flame retardant ratings.
Perkalite improves the gas barrier properties and mechanical strength of packaging materials, enabling reduction in the amount of packaging material or extending the shelf life of perishable goods. In addition the flow properties are improved, resulting in e.g. better thermoforming properties. Typical applications are packaging films, bottles, cups and food trays.
Other typical Perkalite applications can be found in: car tires, polypropylene storage systems, highly filled polymer compounds (as dispersion aid), and several general polypropylene and rubber goods.
