What causes polyethylene wax to precipitate?

1. More internal lubrication, good fluidity and shorter plasticizing time, but excess internal lubrication will change into external lubrication effect and cause precipitation;

2. The external lubrication is too much, and the plasticization is poor and slow. Because of the poor compatibility with PVC, the excessive lubrication will cause serious precipitation; Therefore, the internal and external lubrication should be balanced.

3. The influence of small molecular substances in lubricants. For example, monoglyceride is a good internal lubricant. However, due to the fact that the manufacturer adds a large amount of glycerol in the production process to reduce the cost, the monoglyceride contains a lot of glycerol components, and the glycerol content is low, which is easy to precipitate in the PVC processing process. The actual addition of good monoglyceride is correct and will not cause precipitation, Monoglyceride is also an antifogging agent and a drip agent in film materials.
