Rushan Beihua tells you the solubility of polyethylene wax in the solvent

Polyethylene wax (PEW) is a low molecular weight polyethylene wax with a molecular weight between 500 and 1000. PEW sources come in three ways: ethylene catalyzed polymerization; high molecular weight polyethylene thermal degradation; polyethylene plant by-products.
Polyethylene wax (PEW) is a low molecular weight polyethylene wax with a molecular weight between 500 and 1000. PEW sources come in three ways: ethylene catalyzed polymerization; high molecular weight polyethylene thermal degradation; polyethylene plant by-products. At present, foreign manufacturers generally use the polymerization method to produce PEW, this method produces PEW molecular weight distribution narrow, molecular size can be artificially controlled, the disadvantage is that must be carried out in large devices, capital investment. Domestic manufacturers generally use high molecular weight polyethylene thermal degradation method to produce PEW. This method uses raw materials can be polyethylene resin, it can be polyethylene waste plastic, the former product grade is high, the latter product level is low; there are some manufacturers of polyethylene plant by-product. PEW is widely used, especially after micronized treatment. PEW powder can be used as a fine chemical products are widely used in various fields, the value-added products greatly improved.
      Polyethylene wax device by-product PEW, due to low purity, wide molecular weight distribution, wide melting range, severely limit the application areas. Manufacturers generally to wax tablets or through a simple dusting device made PEW powder sold directly. At present, although the existing technology to ensure that the PEW powder particle size to micron level, but the raw material has been defective and has not been changed.
      PEW after grading and refining, can completely overcome the defects of raw materials, greatly improve the application of targeted and expand its application areas, product performance and added value will be greatly improved. In order to make the PEW grading and refining, the choice of the PEW solvent system is very important, and the literature on this aspect has not been reported, so this work has been carried out in this paper.

Companies specializing in the wholesale price of a large number of cash to provide polyethylene wax, oxidized polyethylene wax, wax emulsion!
