Rutile TiO2 R556 CAS 13463-67-7 for Rubber Footwear and Mechanical Goods
Rutile TiO2 R556 is rubber‑purpose rutile titanium dioxide specially developed for rubber footwear and mechanical rubber products. Adopting alumina‑silica inorganic composite surface coating and strict particle‑size classification, the pigment can be quickly wetted and evenly dispersed in natural rubber and synthetic rubber systems during mixing process. It provides excellent whiteness and tinting power, effectively upgrading surface gloss and color uniformity of light‑colored rubber finished pa
Product Overview
Rutile TiO2 R556 CAS 13463‑67‑7 is sulfate‑process rutile titanium dioxide developed for footwear and mechanical rubber applications. Balanced oil absorption meets formulation requirements of shoe‑making rubber and general‑purpose mechanical rubber. Composite surface modification improves interfacial compatibility between pigment and rubber polymer. This grade addresses common challenges including poor mixing dispersion, surface speckles, uneven color and insufficient aging resistance for light‑colored rubber goods. Stable technical parameters suit mass‑production workflows: internal mixer mixing, open mill processing, molding and extrusion.
Key Features
- Excellent dispersion within rubber matrix, easy processing on internal mixer or open mill, effectively reduce speckle and color‑spot defects.
- High whiteness and tinting strength, produce bright, uniform visual appearance for light‑colored rubber footwear and mechanical rubber parts.
- Optimized oil absorption value, fits footwear rubber formula, brings no negative influence on vulcanization rate and cross‑linking performance.
- Moderate UV‑shielding capacity, improves anti‑aging performance for rubber finished products under daily service conditions.
- Good compatibility with natural rubber, SBR, BR, vulcanizing agent, accelerator and other standard rubber auxiliaries.
- Chemically inert property, maintains stable color performance during long‑term storage and end‑use.
Main Applications
‑ Rubber footwear: rubber outsole, midsole and light‑colored shoe accessory components‑ Mechanical rubber goods: rubber gaskets, anti‑vibration pads, buffer rubber parts‑ Light‑color miscellaneous rubber fittings for machinery and hardware industry‑ General‑purpose light‑colored rubber sheets, rubber hoses and rubber rollers‑ Other rubber products requiring whitening, tinting and premium surface finish
Usage Recommendation
‑ Recommended dosage: 2‑11 phr calculated on rubber weight, adjust according to target whiteness and color requirements.‑ Add TiO2 R556 in the early mixing phase of internal mixer or open mill.‑ Ensure adequate mixing time to realize full homogeneous pigment dispersion.‑ Avoid raw‑material caking caused by moisture before feeding.‑ Conduct small‑batch compound mixing, vulcanization and performance testing prior to mass production.
Storage & Packaging
‑ Packaging: 25kg moisture‑proof kraft paper bag with PE inner liner.‑ Storage: Store in dry, cool and ventilated warehouse, keep tightly sealed against moisture absorption.‑ Shelf life: 24 months under standard storage conditions.
