Application Of Titanium White Powder In PVC Heterotype
Nov 16, 2018

The weather resistance is one of the most important properties of PVC heterotype materials used as outdoor products. Its weather resistance mainly depends on titanium dioxide, so high weather resistance is a requirement based on titanium dioxide. Of course, titanium dioxide also plays the role of pigment in heterotype materials, and it is also necessary to give a good appearance and color. The formulation of hard PVC profile is very complex, and the processing is difficult. The requirement of titanium dioxide does not affect the processing performance of other components, and meets the requirements of high-temperature processing for the heat resistance of titanium dioxide, etc..
Heterotype material to titanium dioxide requirements, can be said to be more basic requirements for weather resistance. Therefore, hard PVC heterotype materials are used for high weather resistance rutile titanium dioxide. The molding process of plastic processing mainly includes injection molding, extrusion, pressing, blowing film, hollow molding, etc.. The hard PVC profile is extruded molding. All kinds of molding processes must be heated and sheared during the processing of the raw materials, and each component must be evenly mixed. Therefore, the common requirements are: Titanium white powder should meet the basic heat resistance requirements, should be easy to disperse, and do not affect other components. Processing performance and so on, All the different main assumptions have different effects on the performance of the later application of the product.
Titanium white powder plays an important role in the development of hard PVC heterotype material market. Hard PVC doors and windows have outstanding comprehensive performance, but PVC itself is not weather resistant, it is titanium white powder gives PVC good weather resistance, so that it can be used as an outdoor product. If titanium dioxide can provide more efficient weathering and discoloration performance for heteroforms and appropriately reduce costs, then PVC heteroforms will have a more significant increase in the market share of doors and Windows. In the current plastics industry, hard PVC heterotype materials are one of the main users of high-end rutile titanium dioxide. This industry has reached an average annual growth rate of nearly two digits in the past two decades, not only for domestic high-end rutile titanium dioxide. The request, It also gives great development space and opportunity.
