TITANIUM DIOXIDE IN PAPER: EVALUATE OPACITY AND TRIAL RESULTS
Editable planning/verification record — Yenra
Updated: October 2, 2026
Article: https://yenra.com/titanium-dioxide-for-paper/

Purpose: Compare candidate grades and trial sheets using defined opacity, brightness, basis weight, retention and cost assumptions.
Intended reader: Paper product developers, mill trial teams, and technical buyers

HOW TO USE
Save a working copy. Enter the actual specification, units, assumptions and evidence references in each field. Preserve original observations and record changes. Have the responsible reviewer resolve missing or conflicting requirements before release. Examples below are fictional teaching inputs, not process settings or acceptance standards.

RECORD
1. Paper application, grade, furnish and customer optical requirements:
   ____________________________________________________________

2. Pigment grade/lot, supplied form, dry-solids fraction and handling requirements:
   ____________________________________________________________

3. Wet-end or coating addition, formulation and retention/process conditions:
   ____________________________________________________________

4. Basis weight, caliper, moisture and conditioning of each sample:
   ____________________________________________________________

5. Opacity method, backing, instrument and individual results:
   ____________________________________________________________

6. Brightness/whiteness method, illuminant/observer, UV condition and results:
   ____________________________________________________________

7. Dry pigment added in kg per gross dry paper tonne; retained pigment evidence:
   ____________________________________________________________

8. Dated price and currency per kg dry pigment equivalent; conversion from slurry if needed:
   ____________________________________________________________

9. Acceptable-paper fraction, rejection reasons and excluded cost categories:
   ____________________________________________________________

10. Replicate trials, operating effects, acceptance decision and retest triggers:
   ____________________________________________________________


WORKED EXAMPLE AND LIMITS
FICTIONAL: A uses 20 kg dry pigment/gross dry paper tonne at $3.00/kg = $60.00/t; acceptable-paper fraction 0.95 gives $63.16 pigment cost/acceptable tonne (rounded). B uses 18 kg/t at $3.20/kg = $57.60/t; fraction 0.90 gives $64.00/acceptable tonne. All rates and prices are invented; calculation excludes other materials, energy, downtime and rework credits. Fractions describe trial output acceptance, not pigment retention.
