At K2013, Lewa GmbH will show its new Ecofoam System for metering blowing agents during the extrusion of insulating boards, packaging films and molded parts (Hall 7a, Booth B35-4).

Ecofoam includes a pump, measurement and control technology. The unit conveys a volume of blowing agent proportional to the speed of the extruder, ensuring exact metering even when pressures fluctuate.

Lewa, of Leonberg, Germany, also will show heated systems for metering of additives in extruders, such as flame retardants, slip agents, anti-static agents and plasticizers.
