Rutile TiO2 R868 CAS 13463-67-7 High Opacity for Plastic Sheet and Injection Molding
Rutile TiO2 R868 is plastic‑special rutile titanium dioxide adopting alumina‑organic composite surface modification. Optimized particle‑size distribution endows it with outstanding opacity, high hiding power and brilliant whiteness. It disperses evenly inside resin matrix during sheet extrusion and injection molding process, effectively reducing surface grain and speckle defects. It possesses reliable high‑temperature thermal stability to resist yellowing under processing temperature, together w
Product Overview
Rutile TiO2 R868 CAS 13463‑67‑7 is produced by sulfate process with plastic‑oriented composite surface coating. Strict particle‑size control delivers high opacity, proper oil absorption and favorable powder fluidity. This grade is tailored for plastic sheet extrusion and injection‑molding applications. It solves common problems such as insufficient covering power, uneven whiteness and surface blemishes of plastic sheet and injection‑molded parts. Consistent product quality supports large‑scale continuous extrusion and injection production.
Key Features
- Super‑high opacity and hiding power, realize excellent covering performance for plastic sheet and thick‑wall injection‑molded products.
- High tinting strength, obtain ideal whitening effect with reasonable pigment dosage.
- Good thermal stability, anti‑yellowing under high‑temperature sheet extrusion and injection molding conditions.
- Excellent resin dispersibility, lower speckle and grain defects on finished plastic surface.
- Low photocatalytic activity, improve anti‑aging performance of end plastic articles.
- Wide resin compatibility, fit for PP, PE, ABS, PS and other general‑purpose and modified plastics.
Main Applications
‑ PP, PE, ABS, PS extruded plastic sheet, plate and thick sheet‑ Various injection‑molded household plastic parts, electronic housing and plastic components‑ Modified compound for sheet and injection molding‑ Color masterbatch for plastic sheet and injection products‑ Plastic products requiring high opacity and bright white appearance
Usage Recommendation
‑ Direct compounding dosage: 1%‑6% by weight; masterbatch pigment loading: 20‑50 wt%, adjust according to opacity requirement.‑ Fully premix with resin and additives before extrusion or injection processing.‑ Keep raw material completely dry before feeding; moisture will trigger bubbles and silver streaks.‑ Optimize processing temperature to give full play to thermal stability performance.‑ Perform small‑batch trial extrusion or injection test 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.
