Product classification Masterbatch particle size is determined according to the negotiation between the supplier and the buyer. The specifications are: similar cylinders with a particle size of 1.5mm ~ 3.0mm and a length of 2.5mm ~ 3.0mm. 2 The performance project has corresponding requirements for 8 indicators including abnormal masterbatch content, 100-grain weight, powder content, intrinsic viscosity, filter press value, melting point, moisture content, and fiber coloring batch error 4△E (CMC2:1). .
