White Masterbatch for Plastics: TiO₂ Grades, TDS & Applications | Masterbatch.vn
5/5 - (2 votes)
White Masterbatch is a concentrated plastic compound containing Titanium Dioxide (TiO₂) dispersed in a compatible carrier resin. It is widely used to produce white coloration, improve opacity, increase brightness and enhance the visual appearance of plastic products.
In industrial plastic manufacturing, white masterbatch affects more than just the final color. The formulation can also influence:
Opacity and covering power
Surface brightness and gloss
Pigment dispersion
Processing performance
Certain physical and mechanical properties
Production cost
At Masterbatch.vn, white masterbatch solutions can be developed for different polymers, processing technologies and application requirements, including PE, PP, LDPE, LLDPE and HDPE systems.
1. Overview of White Masterbatch in the Plastics Industry
White Masterbatch is produced by dispersing a high concentration of TiO₂ pigment into a polymer carrier resin together with selected dispersing and processing additives.
During plastic processing, the masterbatch is mixed with the base resin and melted. The TiO₂ pigment is then distributed throughout the polymer matrix to create the required level of whiteness and opacity.
The final performance depends on several factors, including:
TiO₂ type and concentration
Pigment dispersion
Carrier resin compatibility
Masterbatch dosage
Product thickness
Processing temperature
Processing technology
Base polymer
Therefore, selecting the right white masterbatch grade is important for achieving consistent production quality.
2. White Masterbatch Classification by Composition
White masterbatch for plastics can generally be divided into two major groups according to the formulation.
2.1. White Masterbatch Without CaCO₃
High-Purity White Masterbatch – No Filler
This type of white masterbatch is formulated primarily with TiO₂, carrier resin and functional additives, without calcium carbonate filler.
Typical Composition
TiO₂: approximately 30%–70%
Carrier resin: PE, PP, PS, ABS or other polymers depending on the application
Dispersing and processing additives
Key Characteristics
White masterbatch without CaCO₃ is generally selected for applications requiring:
High whiteness
Bright white appearance
Strong opacity
Excellent pigment dispersion
Lower filler-related impact on certain mechanical properties
High-quality surface appearance
It is particularly suitable for products where appearance, color consistency and overall product performance are important.
Typical applications include premium packaging, thin films, injection-molded products and products intended for demanding domestic or export markets.
2.2. White Masterbatch with CaCO₃ Filler
Economical White Masterbatch with Calcium Carbonate
This formulation contains TiO₂ together with Calcium Carbonate (CaCO₃), polymer carrier resin and selected additives.
Typical Composition
TiO₂: approximately 30%–70%
CaCO₃: according to the formulation
Carrier resin: PE, PP or other suitable polymers
Functional additives
Key Characteristics
White masterbatch containing CaCO₃ can provide:
Good white coloration
Good opacity
Cost optimization
Suitable processing performance
Potential filler-related cost advantages
It can be suitable for general-purpose plastic products where the balance between color performance and production cost is an important consideration.
Typical applications include standard packaging, plastic bags, general industrial products and other cost-sensitive applications.
3. Common TiO₂ Concentrations for White Masterbatch
The appropriate TiO₂ concentration depends on the required whiteness, opacity, product thickness, dosage and processing conditions.
The following grades are examples of commonly used concentration levels:
Grade
TiO₂ Content
Typical Characteristics
Typical Applications
WB-30
30%
Moderate whiteness and opacity
General packaging
WB-40
40%
Good whiteness and stable coloration
Blown bags, extrusion
WB-50
50%
High whiteness and opacity
Films, bottles, containers
WB-60
60%
Bright white color and good dispersion
Appearance-sensitive products
WB-70
70%
Premium high-concentration formulation
Export and technical applications
These grade names are indicative and may be customized according to customer requirements.
Important Technical Note
At the same TiO₂ concentration, a formulation without CaCO₃ may provide higher whiteness and opacity than a formulation containing CaCO₃, depending on the TiO₂ grade, dispersion quality, carrier system, dosage and final product thickness.
Therefore, TiO₂ concentration alone should not be used as the only parameter when comparing white masterbatch performance.
4. Typical Technical Data Sheet (TDS)

5. Practical Applications of White Masterbatch
White masterbatch is widely used across different plastic-processing technologies.
5.1. PE / LLDPE Film Blowing
White masterbatch can be used in:
Shopping bags
Garbage bags
Packaging films
Agricultural films
Industrial films
Flexible packaging
For thin-film applications requiring high whiteness and good pigment dispersion, a high-quality formulation without CaCO₃ may be preferred.
5.2. Injection Molding
White masterbatch is widely used for:
Bottle caps
Plastic containers
Household products
Plastic components
Consumer products
Technical parts
The masterbatch carrier should be compatible with the injection-molding resin.
5.3. Extrusion
Applications include:
Plastic pipes
Plastic sheets
Profiles
Extruded components

Thermal stability and dispersion are important factors when selecting a masterbatch for extrusion.
5.4. PP Woven and Nonwoven Products
White masterbatch is also used in:
PP woven bags
Woven packaging
Nonwoven fabrics
Industrial sacks
Agricultural products
For these applications, the masterbatch should be selected according to the PP grade, extrusion conditions and required whiteness.
5.5. Bottles, Containers and Rigid Packaging
White masterbatch can be used in:
Plastic bottles
Jars

Canisters
Rigid packaging
Household packaging
The formulation should be selected according to the polymer, processing method and required product appearance.
6. Technical Recommendations by Application
Selecting white masterbatch according to the product structure and production requirements can improve overall performance.
Thin Products – High Whiteness Required
For thin films and products where a bright white appearance is important:
Recommended: high-dispersion, high-purity white masterbatch without CaCO₃.
Potential benefits include:
Higher visual whiteness
Better pigment dispersion
Stronger opacity
Attractive surface appearance
Thick Products – Cost Optimization Required
For thicker products where production cost is a major consideration:
Recommended: white masterbatch containing CaCO₃, provided the formulation is compatible with the required product performance.
Potential benefits include:
Cost optimization
Good white coloration
Suitable opacity
Efficient production
The optimum formulation should always be confirmed through actual production trials.

8. How to Select the Right White Masterbatch
Choosing the correct white masterbatch requires consideration of several technical parameters.
Step 1: Identify the Base Polymer
Determine whether the application uses:
LDPE
LLDPE
HDPE
PP
PS
ABS
Other polymers
Step 2: Identify the Processing Technology
Determine whether the product is manufactured by:
Film blowing
Injection molding
Extrusion
Blow molding
Fiber spinning
Woven production
Nonwoven production
Step 3: Define the Required Whiteness
Determine the required:
Whiteness
Opacity
Brightness
Surface appearance
Color consistency
Step 4: Select the TiO₂ Concentration
A higher TiO₂ concentration does not automatically mean better performance in every application. The correct grade depends on the masterbatch dosage and final product requirements.
Step 5: Conduct a Production Trial
Testing the masterbatch on the actual production line is recommended before placing a large commercial order.
