Rutile Titanium Dioxide R900 CAS 13463-67-7 Plastic Grade for Polyolefin Masterbatch
Rutile Titanium Dioxide R900 is dedicated plastic‑grade rutile titanium dioxide modified by alumina‑organic composite surface treatment. It possesses outstanding high‑temperature thermal stability, high hiding power and brilliant whiteness. Under high‑temperature extrusion and granulation conditions for polyolefin masterbatch, it resists yellowing and discoloration. It shows excellent compatibility and dispersion in PE, PP resin systems, reducing speckle defects during masterbatch production. Wi
Product Overview
Rutile Titanium Dioxide R900 CAS 13463‑67‑7 is produced by sulfate process with exclusive composite surface modification for plastic application. Strictly controlled particle‑size distribution brings low oil absorption, good fluidity and low photoactivity. This grade is specially developed for polyolefin masterbatch. It solves common pain points of plastic masterbatch such as high‑temperature yellowing, poor dispersion and surface particle spots. Reliable quality meets continuous extrusion granulation production requirements of PE, PP masterbatch.
Key Features
- Excellent high‑temperature thermal stability, anti‑yellowing under polyolefin extrusion granulation temperature.
- Low photocatalytic activity, slow down plastic aging and improve service life of finished plastic products.
- High hiding power and tinting strength, achieve ideal whitening effect with reasonable addition dosage.
- Superior dispersion in polyolefin resin, reduce screw torque, avoid grain and speckle defects.
- Low oil absorption, improve filler loading capacity for high‑concentration color masterbatch formula.
- Good compatibility with PE, PP and various auxiliaries for plastic masterbatch.
Main Applications
‑ PE, PP polyolefin color masterbatch and white masterbatch‑ Polyolefin filled masterbatch and functional masterbatch‑ Injection‑molded polypropylene and polyethylene plastic products‑ Extrusion‑molded polyolefin plastic parts‑ Plastic modification requiring high‑temperature processing resistance
Usage Recommendation
‑ Recommended dosage: 20%‑60% in masterbatch, adjust according to whitening and hiding requirements.‑ Mix fully with resin, dispersant and other additives, then carry out twin‑screw extrusion granulation.‑ Keep material dry before feeding, moisture will cause bubbles and surface defects on masterbatch.‑ Control processing temperature within the recommended range to give full play to anti‑yellowing performance.‑ Complete small‑batch trial extrusion 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.
