We should often see many powder filler masterbatch, most people think much powder filler masterbatch quality is poor, this understanding is one-sided, indeed, most of the powder of filling masterbatch is low, which is the cost constraints. A situation is still just to do the material immediately transport packaging, so too will produce more powder, the normal situation is produced after cooling to put a few genius transportation can reduce the powder.Good difference depends on filling masterbatch quality in the selection of raw materials quality, mainly is the powder, here I talk about calcium carbonate (because the market filled masterbatch basically is calcium carbonate as the main), one is the powder fineness, simple to understand, the more fine powder dispersion is better (this is not absolute.). The two is the carrier or carrier, general PP, PE, PE than PP to relatively good, or the new material and feed back the. How much is three carrier content, are generally in the 5~10% between the carrier, of course the more the better, but the cost increase vector. Four additives, is generally used in PE wax or wax PP, but low level basically wax to do, of course, are also useful for EBS, there is a stearic acid quality
