Now the unprecedented development of industry, many new technology and materials appear in our line of sight, but how can we ensure the quality of the material? This time Rushan Beihua New Materials Technology Co., Ltd. will explain how to distinguish between high-quality polyethylene wax and low-grade polyethylene wax difference
Now the unprecedented development of industry, many new technology and materials appear in our line of sight, but how can we ensure the quality of the material? This time Rushan Beihua New Materials Technology Co., Ltd. will explain how to distinguish between high-quality polyethylene wax and low-grade polyethylene wax difference
Polyethylene wax, also known as PE wax, is a low molecular weight polyethylene with a molecular weight between 1500-2500 and a melt viscosity of 290 centipoise (140 ° C) with a melting point of 107 ° C and its viscosity and hardness close to paraffin.
  Currently on the market price of polyethylene wax is generally 13,000 yuan / ton, while the price of fake polyethylene wax is only 8000-9000 yuan / ton.
  Polyethylene wax is commonly used in PVC processing outside the lubricant, and a part of the internal lubrication, the quality of polyethylene wax is generally not more than 0.5Phr, to meet the PVC molding process.
  The impact of poor quality polyethylene wax:
  At present, the market there have been a large number of shoddy polyethylene wax, the analysis, this polyethylene wax is made of waste polyethylene (PE) with paraffin, and in the waste of PE material in high molecular weight HDPE, There are LLDPE and LDPE, and even a small amount of industrial or domestic waste. The viscosity of the fake polyethylene wax is much greater than that of the formal polyethylene wax. The PVC product is processed with this fake polyethylene wax, which not only has poor lubrication effect, but also produces serious precipitation during the processing and adheres to the die Export or sizing inside the diameter, especially in the production process of conical twin-screw extruder not only produce adhesion, but also to promote the product discoloration or even decomposition, so that the normal production operation interruption, resulting in the loss of manufacturers.
  The use of polyethylene wax is less, the use of high-quality polyethylene wax does not increase the cost per ton of products, but if the use of cheap low-quality polyethylene wax and the production is not normal, the loss will be far greater than the quality Polyethylene wax and shoddy polyethylene wax between the difference, which is also recommended manufacturers to use high-quality polyethylene wax reasons.

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