Titanium Dioxide R886 CAS 13463-67-7 for Polypropylene and Polyethylene Compound
Titanium Dioxide R886 is dedicated rutile titanium dioxide for polypropylene and polyethylene compound. With alumina‑organic composite surface modification, it achieves excellent wetting and dispersion in PP and PE resin matrix. It provides high hiding power and bright stable whiteness, resists thermal yellowing during twin‑screw compounding and granulation process. Low photocatalytic activity helps retard photo‑aging of polyolefin finished products. It has good compatibility with polyolefin res
Product Overview
Titanium Dioxide R886 CAS 13463‑67‑7 is manufactured by sulfate process with polyolefin‑oriented composite surface coating. Well‑controlled particle‑size distribution brings low oil absorption, good powder fluidity and restrained photo‑chemical activity. This grade is custom‑developed for PP and PE compounding and modification. It solves common pain points such as poor pigment dispersion, surface speckles and thermal discoloration during polyolefin compound granulation. Stable quality adapts to continuous large‑volume twin‑screw compounding production.
Key Features
- Excellent dispersion in PP and PE resins, reduce surface grain and speckle defects of compound pellets and end‑products.
- Good high‑temperature thermal stability, resist yellowing under polyolefin compounding and granulation temperature.
- High hiding power and tinting strength, deliver outstanding whitening performance for polyolefin compounds.
- Low photocatalytic activity, slow down photo‑oxidative aging and extend service life of polyolefin articles.
- Low oil‑absorption property, support high filler loading for filled PP and PE compound formulas.
- Broad compatibility with polyolefin resin, talcum powder, calcium carbonate, dispersant and polyethylene wax.
Main Applications
‑ Filled and modified polypropylene PP compound‑ Filled and modified polyethylene PE compound‑ PP‑PE blending modified materials‑ Polyolefin functional masterbatch and filled masterbatch‑ Injection & extrusion polypropylene and polyethylene finished products
Usage Recommendation
‑ Direct compounding dosage: 1%‑7% by weight; masterbatch loading: 20‑55 wt%, adjust based on whitening and hiding requirements.‑ Thoroughly premix with resin, fillers and auxiliaries before twin‑screw extrusion granulation.‑ Ensure raw materials are fully dried before feeding; moisture will generate bubbles on compound pellets.‑ Optimize extrusion temperature range to exert anti‑yellowing performance.‑ Conduct small‑batch compounding 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
