Titanium Dioxide R838 is professional rutile titanium dioxide for PVC plastics and color masterbatch, adopting alumina‑silica inorganic‑organic composite surface treatment. It features high tinting strength, superior opacity and good whiteness. The pigment disperses uniformly in PVC resin matrix during mixing and extrusion, effectively reducing surface speckles. It has low photocatalytic activity, improves anti‑aging performance of PVC finished goods, and has good compatibility with various PVC

Product Detail

Product Overview

Titanium Dioxide R838 CAS 13463‑67‑7 is produced by sulfate process with PVC‑targeted composite surface modification. Optimized particle‑size distribution brings proper oil absorption value, good powder flowability and suppressed photo‑chemical activity. This grade is developed for rigid PVC, flexible PVC and corresponding color masterbatch. It effectively addresses typical pain points including insufficient dispersion, surface speckles and premature aging of PVC articles. Consistent product quality supports large‑volume continuous mixing, extrusion and granulation for PVC compounds and masterbatches.

Key Features

Excellent dispersion performance, easy wetting in PVC matrix, reduce speckle defects during mixing and extrusion.
High hiding power and tinting strength, deliver satisfied whitening and tinting effect for PVC goods.
Low photocatalytic activity, retard UV‑triggered aging and discoloration of indoor and outdoor PVC products.
Broad additive compatibility, stable with calcium‑zinc, lead‑salt stabilizers, fillers and processing aids.
Moderate oil absorption, suitable for both rigid hard‑PVC and flexible soft‑PVC formula development.
Good thermal stability, low die buildup during long‑run continuous extrusion and granulation operations.

Main Applications

‑ Rigid PVC: profiles, pipes, sheets, injection‑molded PVC components

‑ Flexible PVC: PVC film, artificial leather, wire & cable insulation materials

‑ PVC white masterbatch and tinting color masterbatch

‑ Filled and modified PVC compound formulations

‑ General‑purpose indoor and light‑duty outdoor PVC plastic products

Usage Recommendation

‑ For PVC compound: recommended dosage 2‑8 phr, adjust according to whiteness and weather‑resistance target.

‑ For PVC color masterbatch: pigment loading 20‑55%, cooperate with wax, dispersant and other auxiliaries.

‑ Fully premix with PVC resin, stabilizer and fillers in high‑speed mixer.

‑ Keep raw material completely dry before feeding; moisture will induce bubbles and surface streaks.

‑ Conduct small‑batch trial mixing or 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.
