Parsing the titanium pigment application in PVC profile
2013.09.02 08:29PVC profile used as outdoor products,weathering is one of the most important performance.Its weather resistance,mainly depends on the value chain,and therefore high weatherability is titanium dioxide is the most basic requirements.Of course titanium white pigment also plays a role in mechanical,provide a good appearance is also a must.Rigid PVC profile formula is very complex,high processing hard workers,require titanium pigment does not affect the other components of the machining performance,and meet the requirements of high temperature processing of titanium white heat resistance and so on.?xml:namespace>
Special requirement for titanium dioxide,weatherability,so to speak is the most basic requirements.So rigid PVC profile using a high weather resistance of rutile type titanium pigment.Plastic processing and molding process is mainly include injection molding,extrusion,calendering,blown film,blow moulding,etc.,which is rigid PVC profile extrusion.Various molding process in the process must be to heat and shearing of raw materials,mixing the components,so the common requirement is:titanium dioxide should meet the basic requirements,should be easy to disperse heat resistance,will not affect the other components of the machining performance,etc.,the difference is mainly different influence on the properties of products in the late application.
Titanium dioxide in rigid PVC profile plays a quite important part in the development of the market.Has outstanding comprehensive performance hard PVC doors and Windows,but PVC is not weather resistance,it is titanium dioxide gives good weatherability PVC,make it can be used for outdoor products.If titanium dioxide can offer more efficient weather resistance for different profile change color performance,and reduced the cost,the PVC profile in Windows and doors market share there will be more obvious ascension.Plastic industry at present,rigid PVC profile is the main users of high-end rutile type titanium pigment,one of the industry nearly 20 years to reach nearly double-digit annual growth,not only for domestic demand high-end rutile type titanium pigment,but also provides a huge space for development and opportunity.
