Tailored Propellants

Riverdale

The new range of liquid propellant +foam from Riverdale Global, Aston, Pennsylvania, USA, apparently supports uniform distribution and controlled foaming of thermoplastics as masterbatches in pellet form. The chemical blowing agent (CBA) formulations in the new liquid additive range include the standard exothermic azodicarbonamide CBA, an endothermic CBA and a combination of the two. All are added at a letdown ratio of 0.5 to 1.5 %, which, according to the manufacturer, is a low proportion for a masterbatch. Among the resins with which they can be used are polyolefins, polystyrene, acrylonitrile butadiene styrene (ABS) and other polymers.

As the liquid blowing agents are not heated during production, the manufacturer says they can be blended more gently into the base resin, with the result that pre-decomposition of the chemical blowing agent is less of a concern. Since liquid additives can be metered into the process with precision and will disperse more uniformly in the melt than masterbatch, processors are better able to achieve the target density reduction, according to Riverdale.
