What is the role of polyethylene wax in color masterbatches? Polyethylene wax plays a lubricating and dispersing role in the color master batch system, increasing compatibility with resins such as polyethylene, polyvinyl chloride, polypropylene, etc.

Ethylene bis stearamide (EBS) is a new type of plastic lubricant developed in recent years, widely used in the molding and processing of PVC products, ABS, high impact polystyrene, polyolefin, rubber, and plastic products. Compared with traditional lubricants such as paraffin, polyethylene wax, and stearate, it not only has good external lubrication effect, but also has good internal lubrication effect, This improves the flowability and demolding ability of melt separated plastics in plastic mol

Coupling agents refer to compounds with polar groups at both ends of molecules, which can improve the bonding strength of items and have a wide range of applications in glass processes, metal, ceramic adhesive industries, and other fields.

Rubber is widely used in industries, agriculture, transportation, machinery manufacturing, medical and health fields, and daily life due to its strong elasticity, good insulation, plasticity, tensile strength, and wear resistance. Pe wax has stable chemical stability, good wear resistance, and high hardness. As a rubber processing aid, it can enhance the diffusion of fillers, increase extrusion molding rate, increase mold flow rate, facilitate demolding, and improve the surface brightness and sm

As is well known, polyethylene wax is widely used in color masterbatches. Today, Sainuo will take you to understand the selection principles of pe wax in the production of color masterbatches.

Zinc stearate is a white powder that is insoluble in water. Mainly used as a lubricant and release agent for styrene resin, phenolic resin, and amino resin. At the same time, it also has the function of vulcanizing active agent and softener in rubber.
Sainuo Zinc Stearate, with less dust, more hygienic and environmentally friendly to use; Significantly inhibits initial coloring,

Today, Qingdao Sainuo will take you to learn about commonly used plastic additives in the chemical industry. How many of these additives have you used?

Polyethylene wax has good stability and better thermal stability when applied in hot melt adhesives. Therefore, it does not precipitate at high temperatures and will not have any impact on the external performance of the hot melt adhesive. The hot melt adhesive produced by adding polyethylene wax has good cold resistance, heat resistance, acid alkali salt medium corrosion resistance, thermal stability, anti slip, good fixation, high bonding strength, and excellent temperature resistance.

Many PVC manufacturers place great importance on the acid value of oxidized polyethylene wax when choosing lubricants. Why is this? In the actual processing of PVC, the higher the acid value, the faster the plasticization rate of the oxidized pe wax increases. The acid value represents the polarity of the oxidized polyethylene wax and is positively correlated. The higher the acid value, the greater the polarity of the oxidized pe wax.

The simplest way to detect Zinc stearate
First, choose zinc from large factories or Zinc stearate from Qingdao Sanuo; Secondly, after melting, the normal state is close to transparency; The third is to measure the melting point. The melting point of zinc is about 120 degrees. If the boiling water melts immediately, it must be adulterated; The fourth is to start the machine and give it a try, to see the current, pressure, and melting point.

Calcium stearate was initially used as an auxiliary stabilizer in PVC, mainly to absorb chloride ions generated by PVC degradation; At the same time, we should also find that Calcium stearate is also widely used in polyolefin formulations. Maybe not many people know the purpose of using Calcium stearate in polyolefin formulations in the initial design. In fact, Calcium stearate was originally used in polyolefin formulations to absorb some halogen ingredients added during polyolefin polymerizatio

Calcium stearate is a white powder, insoluble in water, cold ethanol and ether, soluble in hot benzene, benzene, Turpentine and other organic solvents, slightly soluble in hot ethanol and ether. When heated to 400, it slowly decomposes and is flammable. When exposed to strong acids, it decomposes into stearic acid and corresponding calcium salts, which are hygroscopic.
