Company Profile

TINOX CR-1220 Chloride Process Titanium Dioxide with Excellent Performance for Plastics

TINOX® CR-1220

Masterbatch Solutions Specialist

Premium rutile TiO₂ engineered for high-performance masterbatch applications

CR-1220 in Masterbatch: Core Advantages

Optical Excellence

CIE L* ≥97.0 brightness
Blue undertone (b* ≤2.0)
Reynolds tinting strength ≥2000

Processing Benefits

Hegman dispersibility ≥6.5
Oil absorption ≤16 g/100g
710 kg/m³ bulk density

Masterbatch Application Scenarios

1. Consumer Electronics Housings

Typical Polymers: ABS, PC/ABS, HIPS

CR-1220's Role:

Provides the premium "tech white" appearance demanded by high-end devices
Maintains color stability under UV exposure (Class B weatherability)
Enables thin-wall molding without flow marks or uneven coloration

Usage Recommendations:

Recommended let-down ratio: 1:20 to 1:30 for optimal cost/performance
Combine with UV stabilizers for outdoor electronics applications
Pre-dry masterbatch at 80°C for 2 hours when processing hygroscopic polymers

2. Food Packaging Masterbatch

Typical Polymers: PP, HDPE

CR-1220's Role:

Delivers FDA-compliant whiteness for food contact applications
Provides excellent opacity to protect contents from light degradation
Maintains polymer mechanical properties at high loadings

Usage Recommendations:

For thin-wall packaging, use 1:50 let-down ratio to maintain clarity
Combine with anti-block agents to prevent sticking in film applications
Process at 200-220°C for PP to optimize dispersion

3. Automotive Interior Components

Typical Polymers: PP, TPO, ABS

CR-1220's Role:

Withstands long-term UV exposure without yellowing
Provides consistent color matching across different polymer substrates
Resists abrasion and scratching in high-wear areas

Usage Recommendations:

For instrument panels, use 2-3% masterbatch concentration
Combine with heat stabilizers for components near heat sources
Ensure melt temperature exceeds 220°C for optimal dispersion in TPO

Masterbatch Processing Guidelines

Optimal Processing Parameters

Melt Temperature	200-240°C
Screw Speed	60-80% of maximum
Back Pressure	50-80 bar
Screw L/D Ratio	≥25:1

Troubleshooting Guide

Issue	Solution
Uneven dispersion	Increase melt temperature by 10-15°C
Color streaks	Check screw wear, increase back pressure
Yellowing	Reduce residence time, verify thermal stabilizers
