Chemours Titanium Technologies pioneered the development of products that provide high opacity and blue undertone. This optical performance is something that is expected from Ti-Pure™ TiO2 products. R-350 continues Chemours Titanium Technologies’ commitment to produce a TiO2 that can provide bright blue and clean appearance to plastics.
The Ti-Pure™ R-350 surface allows for exceptional processing even in highly loaded TiO2 PE systems. Unique R-350 chemistry permits the product to achieve desirable masterbatch viscosities in a wide variety of polyolefin based resins. This function allows a formulator to minimize the TiO2 impact on melt properties during processing and end use applications.
Melt Flow Index (MFI)
The unique surface of Ti-Pure™ R-350 minimizes volatile materials typically associated with TiO2. Thermogravimetric Analysis highlights the low level of volatiles contained in R-350. This characteristic gives R-350 superior performance in high temperature, thin gage extrusion applications such as polyolefin cast film or extrusion coating.
High Temperature Weight Loss
Another benefit from using Ti-Pure™ R-350 is the ability to use the TiO2 in combination with materials that tend to diskolor. Certain polymer additives can interact with a TiO2 surface. Under UV light illumination, this interaction can lead to diskoloration. The R-350 chemistry minimizes the risk of diskoloration.
Polyethylene Diskoloration
Ti-Pure™ R-350 has the ability to absorb ultraviolet light with minimal impact on the polymer matrix. A means of determining the impact is to monitor the change in surface gloss of a plastic article during ultraviolet exposure. Typically, the surface gloss of an article will decrease as exposure time increases. R-350 performs admirably in comparison to general purpose TiO2 and provides the durability necessary for many polyolefin applications.
Polyolefin Gloss Retention
In ABS resin applications, R-350 provides a bright clean initial color. R-350’s unique surface treatment gives excellent thermal and UV stability, helping to maintain that brand new look. The superior dispersion of R-350 allows ABS to better retain mechanical impact properties in demanding applications. R-350 provides the optimal blend of performance in ABS.
