AkzoNobel introduces Perkalite® synthetic organoclays

AkzoNobel Polymer Chemicals has launched a range of unique and versatile synthetic Layered Double Hydroxide (LDH) organoclays which offer customers improved properties, performance and environmental benefits.

Marketed under the name Perkalite®, with proper compounding, the LDH organoclays delaminate to nanoscale level and form a true nanocomposite. Perkalite nanocomposites feature improved flame retardancy, gas barrier properties and mechanical properties.

The product is suitable for use as a flame retardant synergist in Low Smoke Zero Halogen wire and cable, and in building & construction applications. It also allows a reduction in the amount of conventional flame retardants, resulting in better processing and mechanical properties. In addition, more stringent flame retardant ratings than usual can be achieved.

A key feature of Perkalite is that it fully complies with European and, potentially, U.S. regulations for food contact applications. In the packaging industry, Perkalite is considered to be a breakthrough enabling downgauging, while obtaining better mechanical and gas barrier properties. This benefits the environment by reducing the weight of single use packaging material and provides additional cost savings to customers.

Not only can Perkalite be applied in packaging and flame retardant plastics, it is currently under development for applications in polyolefins, car tires and general rubber goods as well.

The product is manufactured at AkzoNobel’s site in Greiz, Germany, via a proprietary environmentally-friendly process. Perkalite is commercially available on a global scale and in a wide range of grades
