Melt strength for recycled PE
In rPE streams, low melt strength and feedstock variability directly limit line stability and the achievable PCR ratio. Reactive additives address both constraints together.
R305 and R401 target the same problem at different efficiency levels. Selection is made through technical trial together with PE type, PCR source, contamination profile and target PCR ratio.
