Rutile TiO2 R796 CAS 13463-67-7 Aluminum Treated for Plastic and Rubber
Rutile TiO2 R796 is alumina‑treated rutile titanium dioxide specially developed for plastic and rubber industries. The aluminum‑based inorganic surface coating improves powder fluidity and wetting performance in polymer matrix. It possesses high tinting strength and excellent opacity, achieving uniform whitening effect in plastics and rubber compounds. It shows good compatibility with rubber vulcanizing agents, fillers and various plastic auxiliaries. Stable batch‑to‑batch quality makes R796 a c
Product Overview
Rutile TiO2 R796 CAS 13463‑67‑7 is sulfate‑process rutile titanium dioxide with exclusive alumina surface treatment. Optimized particle‑size distribution brings moderate oil absorption and good flowability. This grade is designed for general‑purpose plastic and rubber systems. It solves common problems including poor wetting, uneven color and surface speckles during mixing and vulcanization process. Consistent product quality supports continuous mass production of plastic parts and rubber goods.
Key Features
- Alumina surface treatment enhances powder fluidity and wetting capacity in plastic and rubber matrix.
- High hiding power and tinting strength, provide satisfactory whitening and tinting performance.
- Good compatibility with rubber vulcanizing system, less interference to vulcanization reaction.
- Uniform dispersion, reduce grain and speckle defects of finished plastic and rubber products.
- Moderate thermal stability, keep stable color under plastic processing and rubber vulcanization temperature.
- Cost‑effective performance, fit for large‑batch general‑purpose plastic and rubber production.
Main Applications
‑ General‑purpose hard and soft plastic compounds‑ Rubber products: rubber hose, sealing strip, rubber sheet, shoe sole and rubber accessories‑ Thermoplastic rubber TPR / TPE formulations‑ Plastic‑rubber blending modified materials‑ General‑purpose plastic and rubber color masterbatch
Usage Recommendation
‑ Recommended dosage: 1‑8 wt% for plastic; 2‑10 phr for rubber formula, adjust according to whiteness requirement.‑ Add during high‑speed mixing for plastic, add in internal mixer or open mill for rubber mixing process.‑ Keep raw material dry before feeding, moisture may cause bubbles on finished surface.‑ Avoid excessive processing temperature to maintain stable whiteness.‑ Complete small‑batch mixing trial before formal 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.
