Ti-Pure™ R-105 | Ultra-Durable Rutile Titanium Dioxide for Outdoor Plastics

Ti-Pure™ R-105 is a premium rutile titanium dioxide ($\text{TiO}_2$) pigment manufactured via the advanced chloride process, specifically designed for outdoor plastic applications. Utilizing innovative silica encapsulation technology, it forms a uniform protective barrier that isolates the $\text{TiO}_2$ surface, minimizing photocatalytic reactions, chalking, and crazing under intense UV exposure. Offering a bright profile with a neutral undertone and moderate opacity strength, Ti-Pure™ R-105 is treated with an organic-based material to ensure excellent dry bulk flow, minimized hygroscopicity, and superior dispersion within vinyl matrices.

Ti-Pure™ R-105 – Silica-Encapsulated Rutile Titanium Dioxide for Weather-Resistant Plastics

Product Overview

Ti-Pure™ R-105 is an industrial-grade, dry powder rutile titanium dioxide ($\text{TiO}_2$) pigment explicitly engineered to maximize the lifetime and appearance of outdoor thermoplastic profiles. Produced via a highly controlled chloride process that yields an exceptionally bright $\text{TiO}_2$ base, this multi-purpose plastics pigment solves the core degradation challenges faced by exterior vinyl and polymer systems exposed to harsh weathering.

The defining technological feature of Ti-Pure™ R-105 is its optimized silica ($\text{SiO}_2$) encapsulation technology. By providing a complete, uniform coating over the pigment particles, the silica layer acts as a structural barrier that prevents the $\text{TiO}_2$ from reacting with the surrounding polymer matrix or additives when exposed to solar UV energy. Additionally, the surface is modified with a specialized organic treatment to streamline material handling, optimize dry flow conveyability, and suppress the inherently hygroscopic nature of inorganically coated pigments.

Key Performance Benefits

  • Advanced Silica Encapsulation: Creates a tight, uniform barrier around the $\text{TiO}_2$ surface to isolate it from the surrounding polymer, blocking UV-induced photocatalytic reactions that degrade plastics.

  • Outstanding Weathering Resistance: Actively minimizes common exterior defects such as surface "chalking," structural crazing, and general aesthetic deterioration.

  • Superior Gloss Retention: Specially engineered to preserve the initial gloss and surface smooth profile of outdoor PVC formulations over long extended lifespans.

  • Balanced Optical Profile: Delivers a highly bright aesthetic combined with a neutral undertone and moderate tinting strength, simplifying color formulation work for masterbatch producers.

  • Excellent Processing & Bulk Flow: The organic surface modification drastically improves dry-flow conveyability through automated plant lines and ensures rapid, uniform dispersion within the plastic matrix.

Suggestions for Use & Core Applications

  • Outdoor Rigid Plastics: Highly recommended for premium exterior building components, especially PVC window profile applications.

  • Exterior PVC Products: Engineered for siding, decking, fencing, and other high-exposure structural profiles requiring a reliable combination of brightness, neutral color space, and high durability.

  • Thermoplastic Compounding: Ideal for outdoor masterbatches where moisture absorption must be minimized during dry blending and extrusion.
