polypropylene waxA wide range of applications, due to a variety of advantages, in the market is also a very popular product. But it also has a lot of need to know when using knowledge, after all, there are many users do not understand these. The next small series for everyone to introduce how to choose polypropylene wax?

Although polypropylene wax is widely used, most readers still don't know enough when they see this product. Especially for its characteristics. Just today we take this opportunity to tell you about it. First of all, polypropylene wax has a melting point higher than polyethylene wax, has good lubrication and spreading effect, improves product gloss, and has low melt viscosity. It is a polyolefin processing aid that replaces imported products. Polypropylene wax is now a chemical material, which is made of polyethylene and rubber processing agent. It has the characteristics of high melting point, high hardness, high gloss, and white color. Made of polypropylene. However, in terms of performance, it has a higher melting point, better dispersion and lubrication effect, better gloss and lower melt viscosity. It is a polyolefin processing aid that replaces imported polyolefins. Everyone should know when choosing that it is more advantageous as a dispersing aid, which can quickly and effectively wet the pigment surface and the inside of the aggregate. Therefore, the strong internal cohesion of the aggregate is also well weakened, so that the aggregate is easily dispersed by weaker shear forces. Once the aggregates are dispersed, the wax covers the free surfaces of the nascent pigment particles and stabilizes the dispersion. According to the capillary effect, it is easily understood that the low-viscosity polyethylene wax acts as a wetting agent to more effectively reach the surface of the pigment primary particles which are difficult for the high-viscosity polymer to reach within a certain period of time to remain. Vinyl and polypropylene waxes are preferred.

When selecting polypropylene waxes, it should also be understood that their applicability is currently limited. For general fine fibers, especially fine fibers and BCF fibers for soft wool, floor coverings and textile garments, polypropylene waxes are generally preferred over polyethylene waxes. Of course, this is mainly because of incompatibility, so it is difficult to form a uniform mixture on the micro level, which will lead to phase separation. The important point is that polypropylene waxes are significantly less than either polypropylene or polypropylene waxes, so the different melting characteristics of the two polymers are difficult to handle. The inhomogeneity of the product, improper rheology will cause the end of the spinning process to break, and due to these side effects, the physical properties of the fiber will be reduced during the spinning process. In this case, it is necessary to use a low-viscosity polypropylene wax, which can wet the pigment in a short time due to its low viscosity and good wettability. This temperature is within the melting temperature range of the polypropylene wax. Due to the change in the crystal structure of the polypropylene fibrils, it can be observed that the melt penetrates from the polypropylene matrix to the fiber surface, not only the pure wax, but also the pigment reaches the surface.
