PTBP lot 20150430 was lump, the materials became big lump that lead to very difficult for manual charging and also the color of RD-106 is very high (0.6 G separation sample)
The last campaign used lot 20150402 (ZIBO_China) that also RD-106 color is 0.4 to 0.5 G ( normal should be 0.1 -0.2 G). we doubt about this PTBP so that please, block the materials till we proof the raw material no impact to color.
