This is below our minimum possible dosing level . 0.005% equals 30 grams per hour = not possible. I suggest they have to talk to the masterbatch producer to make a new masterbatch that is x10 weaker. Then we can easily dose 0.05% (300 grams) per hour instead of the impossible 0.005% (30 grams per hour). This will work and be a stable process. It is not good to add any additive at such low addition rates. Think about how difficult for the screw to disperse 0.005%. it means if you have only 1 granule into 20,000 resin granules. Its not a realistic dosing percentage.
