R-350 Titanium Dioxide

Product Information
Product Description
Ti-Pure R-350 is designed to exceed today’s
expectations for a titanium dioxide and set tomorrow’s
standard in plastics formulations. The product is designed
for formulators searching for a single grade of TiO2 withperformance covering a broad range of plastics end uses.
R-350 provides a matchless combination of excellent
dispersion and processing, minimal volatile content,
minimal interaction with polymer additives, durability andthe brightness only a chloride-produced rutile TiO2 canprovide. R-350 is the only TiO2 available that can offersuch an exceptional set of properties.

Chemours Titanium Technologies pioneered thedevelopment of products that provide high opacity andblue undertone. This optical performance is somethingthat 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 pigment is a fine, dry, white powder with the following
general properties:

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 ofpolyolefin based resins. This function allows a formulator
to minimize the TiO2 impact on melt properties during
processing and end use applications (Figure 1).

Suggestions for Use
Ti-Pure™ R-350 is optimized for polyolefin and ABS
applications. R-350 allows a plastics formulator to design
products that can be used in diverse applications ranging
from general purpose plastics, durable/non-durable
plastics and high quality products with critical end use
applications. R-350 demonstrates excellent dispersion,marvelous processibility, exceptionally low volatility andenhanced durability. This combination of functions in one
TiO2 make R-350 the prime choice for high temperature
cast films, exterior films and general purpose applications
while providing excellent assurance against discoloration.

The unique surface of Ti-Pure™ R-350 minimizes
volatile materials typically associated with TiO2.
Thermogravimetric Analysis (see Figure 2) highlights
the low level of volatiles contained in R-350. This
characteristic gives R-350 superior performance in hightemperature, thin gauge extrusion applications such aspolyolefin cast film or extrusion coating.

R-350 performs admirably in comparison to general
purpose TiO2 and provides the durability necessary formany polyolefin applications.

Another benefit from using Ti-Pure™ R-350 is the ability
to use the TiO2 in combination with materials that tend
to discolor. Certain polymer additives can interact with aTiO2 surface. Under UV light illumination, this interaction
can lead to discoloration. The R-350 chemistry minimizes
the risk of discoloration. (see Figure 3).

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 thatbrand new look. The superior dispersion of R-350 allows
ABS to better retain mechanical impact properties indemanding applications. R-350 provides the optimal blendof performance in ABS (Figure 5).
