polyethylene wax CAS号 is CAS:9002-88-4, polyethylene (PE) CAS也 is CAS:9002-88-4. structure is same, difference main/primary is molecular weight different.
in polyethylene (PE) production process in, generate a small amount of oligomer low versus for separation quality polyethylene (PE), also polymer/macromolecule wax polyethylene wax.
polymer/macromolecule micro made main/primary has 3 types 途径:
一 is coarse pellets 出发, use machine powder method, 蒸发凝 shrink method and melt method and other material methods;
二 is utilizing chemical agent function, make formed various dispersion separation 子逐渐 long formed large small micro 粒, can separation is solvent understanding and emulsification types dispersion methods;
三 is adjustment polymerization or degradation made 备. 如PMMA micro powder, can molecular weight PP, dispersion polymerization made 备PS micro pellets, hot understanding formed 辐射裂 understanding made PTFE micro powder.
