Low levels of +Restore™ Additive from Riverdale Global improve properties of PP and HDPE post-consumer recyclate while enhancing flow and part consistency.
Physical property tests carried out by Riverdale Global in cooperation with a molder of packaging containers has demonstrated that +Restore™ liquid additive is even more effective than was originally claimed for improving the performance of plastics regrind based on post-consumer waste.
Other benefits are provided by the +Restore additive, according to Mr. Arbeter: "Because the additive has an affinity for the base polymer, it acts as a lubricant, enhancing melt flow. In addition, the +Restore molecule has a functional group that readily reacts with pigments, fibers, or fillers in the resin, while a different segment of the same molecule is designed to couple with the polymer; as a result, it forms a strong bond between resin and filler without compromising flexibility."
The +Restore additive can be used in all thermoplastic processes, alone or in a blend with Riverdale Global's liquid colors. Typical usage rates are in the 0.1 to 0.5% range.
