Titanium Dioxide R982 CAS 13463-67-7 for Lamination Film and BOPP Film
Titanium Dioxide R982 is professional rutile titanium dioxide specially developed for BOPP and lamination film. With alumina‑organic composite surface modification and multi‑stage fine screening process, oversized coarse particles are strictly controlled. It features high hiding power and pure whiteness, disperses evenly in polypropylene resin during high‑speed casting and biaxial stretching. It effectively reduces fish‑eye and crystal point flaws on thin‑gauge film surface. Excellent thermal st
Product Overview
Titanium Dioxide R982 CAS 13463‑67‑7 adopts sulfate process with film‑specific composite surface coating. Multi‑pass fine screening eliminates coarse impurities. Optimized particle‑size distribution delivers proper oil absorption and superior powder flowability. This grade is engineered for opaque BOPP film and packaging lamination film. It addresses common challenges including fish‑eyes, crystal spots, insufficient opacity and uneven whitening caused by pigment agglomeration. Consistent quality fits continuous high‑speed co‑extrusion, casting and biaxial stretching production lines.
Key Features
- Strict coarse particle control, greatly reduce fish‑eye and crystal‑point defects for thin BOPP lamination film.
- Excellent dispersion inside PP matrix, achieve uniform whitening and high opacity after biaxial stretching.
- High hiding power and tinting strength, reach required opacity at reasonable pigment loading.
- Superior thermal stability, resist thermal yellowing under high‑temperature casting and stretching conditions.
- Low photocatalytic activity, improve light‑aging resistance of packaging lamination film products.
- Good compatibility with PP resin, slip agent, antistatic agent and other BOPP functional additives.
Main Applications
‑ Opaque BOPP co‑extruded lamination film‑ Printing and packaging dry lamination base film‑ Special‑purpose color masterbatch for BOPP biaxial stretching film‑ Polypropylene cast film and thin‑gauge stretched packaging film‑ Other thin‑wall PP film requiring low‑defect and high‑opacity surface
Usage Recommendation
‑ Pigment loading in BOPP masterbatch: 20‑52 wt%; direct compounding dosage: 1‑4 wt%, adjust according to opacity requirements.‑ Fully mix with PP resin and functional additives, granulate via twin‑screw extruder before film production.‑ Ensure complete drying of raw materials before feeding; moisture causes bubbles and longitudinal streaks on film surface.‑ Conduct small‑batch casting and stretching trial to evaluate fish‑eye and surface quality prior to 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.
