What are the advantages of polyethylene wax? How to identify polyethylene wax?

Polyethylene wax is a fully saturated ethylene homopolymer with linear crystallinity. Due to its high crystallinity, it can be used in blends, plastic additives, and rubber manufacturing. Polyethylene wax has unique properties such as high-temperature hardness and low solubility in various solvents. Polyethylene wax is thermoplastic, so you can imagine its behavior when heated. Thermoplastics melt at 110°C, and another interesting feature is that they can be heated and cooled without significant degradation. Polyethylene wax also has limited inter-chain spacing and molecular weight, so the material is highly resistant to chemical erosion, has thermal stability, and is very flexible in preparation and application.

Mainly speaking, polyethylene wax has three advantages: 1. The polyethylene wax used in masterbatches is inexpensive, and the pigment dispersed in 694 can be used to color PVC without spotting, and can also be used to color polyamide to improve demolding. 694 has proven to be an excellent binder for combining pigments with polymer particles, and also an excellent binder for dust-free, non-agglomerated, and mobile pigment concentrates in high-speed mixers. 2. Polyethylene wax for polyvinyl chloride is affordable. Important applications of polyethylene wax in PVC processing. Compared with fatty acid-based lubricants, it does not bring bad luck to melt tension and Vicat softening temperature, and provides excellent anti-sticking and operability. Polyethylene wax can be used to control melting in special processing methods. Even with large amounts, it has good compatibility with other components. 3. Engineering plastics polyethylene wax is inexpensive and cost-effective. Due to the continuous demand for engineering plastics and the efforts of plastics manufacturers to develop special products and new markets, the development of new plastics has increased. Since application technologies are often in a continuous process of improvement, these plastics often lead to processing difficulties. They either have very high molecular weights, so their activity is very poor, or, for example, copolymers used at low temperatures are very sticky after processing.

Identification of polyethylene wax: Polyethylene wax can be low-density polyethylene (LDPE) or high-density polyethylene (HDPE). Generally speaking, HDPE has a higher density and stronger crystallinity, so if you have a way to determine these two properties, you can distinguish them. However, you can use various methods to distinguish PE wax from other materials, such as visual, tactile, and olfactory. Visually, polyethylene wax is similar to a plastic plate, it is a translucent yellow substance. Smooth surface. If the polyethylene wax is cut, there are no impurities or any separation. Tactilely, polyethylene wax is lubricating. At room temperature, polyethylene wax is brittle, and you can also judge it by boiling the polyethylene wax in water for five minutes. PE wax will not deform, but if it contains paraffin or any other impurities, it will deform.
