Chemours Ti Pure R-350

Products Information of Chemours Ti Pure R-350

Rutile titanium dioxide can provide maximum protection for extended outdoor service life. However, not all grades of TiO2 are created equal. For durable polyolefin applications, Ti-Pure™ R-350 has the perfect combination of weatherability, optics, and processibil ity to meet the most exacting requirements.

Chemours Ti Pure R-350 titanium dioxide has been specifically designed to achieve:

• Maximum weather resistance

• Bright, neutral whites

• Color formulation flexibility

• Superior processibil ity

Exceptional Durability

• UV energy is absorbed and dissipated by the fine sized particles. Innovative silica encapsulation technology is used to impart a chemically inert coating on  each TiO2  particle to prevent microcracks, chalking, or other degradation of the plastic.

• It improves the efficiency of UV stabilizers.

• High gloss retention — polyolefin parts look and perform like new, longer.

Pin-point Color

• With the unique combination of a neutral undertone, excellent opacity, and strong brightness, It is the easy solution for matching color tints or delivering bright, clean whites.

Low Volatility

• At elevated temperatures, general grades of titanium dioxide can “de-volatil ize,” creating downstream quality issues like holes or other imperfections, particularly in thin film applications. To compensate, most users end up slowing down their process.

• Resists “lacing” or “de-volatilization” and in the process, allows users to run faster.

Excellent Dispersibility

• Flows easily and disperses readily into a variety of resins, insuring consistently and reliably, high quality products.

• Its optimized surface chemistry enhances bulk flow and improves processing.

Chemours Ti Pure R-350 – Frequently Asked Questions (FAQ)

Q1: What is the primary function of Ti Pure R-350 in polymer systems?

A: Ti Pure R-350 is a surface-treated titanium dioxide pigment designed to provide high hiding power, brightness, and UV stability in demanding polymer applications—particularly polyolefins, PVC, and engineering thermoplastics—while maintaining excellent dispersion and processability during compounding and molding.

Q2: How does the surface treatment of R-350 enhance its performance in plastics?

A: The proprietary inorganic–organic hybrid surface treatment improves compatibility with hydrophobic polymer matrices, reduces agglomeration during melt processing, and helps preserve mechanical properties—such as impact strength and elongation—at typical use levels.

Q3: Is Ti Pure R-350 suitable for food-contact plastic applications?

A: Yes—R-350 is manufactured and tested to meet global regulatory expectations for titanium dioxide used in food-contact polymers, including compliance with major regional frameworks for indirect food additives. Formulators should verify final compliance based on their specific application, processing conditions, and end-use requirements.

Q4: What are recommended handling and storage practices for this pigment?

A: Store in a cool, dry location away from moisture and direct sunlight. Keep containers tightly sealed to prevent dust formation and contamination. Use appropriate industrial hygiene practices—including local exhaust ventilation and NIOSH-approved respirators—when handling the dry powder to minimize inhalation exposure.

Q5: Can R-350 be used in both injection molding and extrusion processes?

A: Yes—R-350 is engineered for robust thermal stability and consistent dispersion across common thermoplastic processing methods, including injection molding, extrusion, blow molding, and rotational molding. Its performance remains stable under typical residence times and temperature profiles encountered in these operations.
