Rutile TiO2 R896 CAS 13463-67-7 for PVC Profile Pipe and Window Profile
Rutile TiO2 R896 is dedicated rutile titanium dioxide for PVC building extrusion products, processed by alumina‑silica inorganic plus organic composite surface modification. It possesses strong UV‑shielding capacity, high hiding power and bright cool‑tone whiteness. During high‑speed extrusion of PVC profiles and pipes, it disperses evenly inside PVC resin matrix, effectively inhibiting outdoor photo‑aging, yellowing and chalking of finished profiles. It shows good compatibility with PVC stabili
Product Overview
Rutile TiO2 R896 CAS 13463‑67‑7 is produced by sulfate process with PVC‑oriented composite surface coating technology. Strictly controlled particle‑size distribution brings low photoactivity, suitable oil‑absorption value and outstanding powder fluidity. This grade is customized for outdoor PVC building extrusion scenarios. It solves common defects of PVC profiles including poor weather resistance, surface speckles, yellowing and brittleness after long‑term outdoor exposure. Reliable quality adapts to continuous high‑speed extrusion production of PVC window profiles, pipes and related UPVC building components.
Key Features
- Powerful UV‑shielding performance and low photoactivity, retard PVC aging, yellowing and chalking under outdoor sunlight exposure.
- High hiding power and cool blue‑toned whiteness, realize stable bright white appearance for PVC profile and pipe surface.
- Excellent extrusion dispersibility, avoid pigment agglomeration and surface grain speckles during high‑speed PVC extrusion.
- Good chemical compatibility, stable matching with calcium‑zinc / lead‑salt stabilizers and other PVC processing auxiliaries.
- Moderate oil‑absorption property, beneficial for formula adjustment of rigid PVC extrusion compounds.
- Stable processing performance, less volatile substance, reduce die buildup during long‑time continuous extrusion.
Main Applications
‑ UPVC plastic window and door extrusion profiles‑ Rigid PVC water supply and drainage plastic pipes‑ PVC building extruded decorative profiles and siding panels‑ Outdoor rigid PVC modified compounds‑ Other weather‑resistant rigid PVC extruded building products
Usage Recommendation
‑ Recommended dosage: 4‑8 phr (parts per hundred PVC resin), adjust according to weather‑resistance and whiteness requirements.‑ Fully premix with PVC resin, stabilizer, calcium carbonate and other additives in high‑speed mixer.‑ Keep raw material fully dry before feeding, moisture will cause bubbles and streaks on profile surface.‑ Match suitable processing temperature range for rigid PVC extrusion.‑ Complete small‑batch extrusion trial before mass formal 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.
