Customer informed that Kaiwu (their customer) found the PVC plastisol plug on the screen during discharging, they suspected that our 167GZ should be the cause of this case. So, they sieved for 25kg of pure 167GZ with screen size 150 micron and they found the residue on screen about 100-200 grams that was very higher than normal trend . (normal trend is around 10 gram) Several lot id were screened and some of them gave residue over 300 grams and also found black particle. PPv already asked sample of residue and problematic resin for our investigation.
After negotiation with customer by BJc on Oct 23, 2015 customer insisted that they can't use it in this application and needed to return this shipment.
