PMM: GranaClean Bio provides biodegradable cleaning

GranaClean This portfolio of granulates from Granula Polymer can be used for mechanically and chemically cleaning injection molding machines and extruders. The granulates expand as they’re used, so they can reach into tricky areas of the machine.

What’s new? GranaClean Bio, a 100 percent biodegradable product that’s compliant with U.S. Food and Drug Administration regulations. Developed specifically for processors of biodegradable polymers such as polylactic acid and polybutylene adipate-terephthalate, it has been available since September.

Benefits Effective regular machine maintenance and contaminant removal, and quick material and color changes. According to Granula Polymer, GranaClean Bio represents a first in the market — the biodegradability of the granulates means that processors no longer have to contaminate their machines with non-degradable polymers and then separate the rejects from the cleaning process. GranaClean users can save on plastic that would otherwise be disposed of as scrap, if machines are not properly cleaned out.
