+Zero Riverdale Global’s +Zero additive helps plastics processors deal with the challenges posed by increased use of post-consumer resin (PCR). Parts made with PCR have different flow properties than those using virgin resins, and this can slow mold release. +Zero prevents the buildup of static electric charges on the surface of plastic parts during processing and reduces surface tension on the parts, to function as a mold release agent. This can result in 25 percent faster cycle times when compared to parts made with untreated PCR.
What’s new? A new formula, which can achieve the same results as the original formula while using 25 percent less of the additive.
Benefits Cost savings. The new formula allows for the use of a higher percentage of recycled material – up to 100 percent regrind – as well as the use of lower-grade recycled material. Faster cycle times improve production, and the need for less additive means these improved results can be attained more cheaply.
