Choosing the right titanium dioxide grade is an important decision for manufacturers that use TiO2 as part of their production process.
Titanium dioxide is used in a wide range of industrial applications, including paints, coatings, plastics, masterbatch, printing inks, paper, rubber, and other products. Different grades can have different characteristics depending on their crystal structure, particle size, surface treatment, TiO2 content, oil absorption, dispersion behaviour, and other technical parameters.
For this reason, manufacturers should not compare products simply by looking at the price per kilogram.
A proper comparison begins with the technical data sheet.
By reviewing specifications systematically, buyers can determine whether a particular grade is appropriate for their formulation, processing conditions, finished-product requirements, and procurement strategy.
For companies sourcing imported material, an experienced Titanium Dioxide Importer can also help buyers understand available grades and compare products according to their application requirements.

Two titanium dioxide products may both be described as white pigments but can have different technical characteristics.
For example, published product specifications can vary in:
Manufacturer technical data sheets demonstrate that these parameters can vary significantly between individual grades.
Therefore, buyers should compare grades based on the properties that actually matter to their application.
The first specification to check is the crystal structure.
Commercial titanium dioxide is commonly available in rutile and anatase forms. India's official trade documentation also recognizes rutile and anatase as two forms of titanium dioxide based on crystal structure.
Rutile is commonly selected for applications where high refractive properties, opacity, durability, and weathering performance are important.
Different rutile grades can still vary considerably in their technical specifications and surface treatments.
Anatase grades have their own application characteristics and are used in selected industrial applications.
The choice between rutile and anatase should therefore be based on the intended application rather than assuming that one grade is universally better.
TiO2 content indicates the proportion of titanium dioxide in the product.
This is one of the basic specifications buyers should review when comparing grades.
Published technical specifications show that different commercial grades can have different minimum or typical TiO2 contents. For example, Tayca lists several rutile grades above 90% TiO2, while its JA anatase grades are listed above 98%.
However, a higher TiO2 percentage alone does not automatically mean that the product will perform better in every application.
Other characteristics such as particle size, surface treatment, dispersion, tinting strength, and oil absorption also influence practical performance.
Particle size is another important technical parameter.
Titanium dioxide grades can have different average particle sizes, with published commercial specifications commonly falling in the sub-micron range. Tayca, for example, lists different grades with average particle sizes ranging from approximately 0.18 to 0.30 micrometres.
Particle size can influence properties such as:
Manufacturers should therefore compare particle-size specifications against the requirements of their particular formulation.
Oil absorption measures how much oil is absorbed by a given quantity of pigment.
It can be particularly relevant to formulation design because it can influence binder or resin requirements and the behaviour of pigment within certain systems.
Different commercial grades can show significantly different oil-absorption values. Tayca's published specifications, for example, range from around 15 to 29 g/100 g across selected grades.
Buyers should therefore avoid assuming that all titanium dioxide grades behave identically in a formulation.
Tinting strength is an important consideration for applications where pigment strength and colour development matter.
A grade with suitable tinting characteristics may help manufacturers achieve their desired colour performance with an appropriate pigment loading.
Some technical data sheets provide tinting-strength values against a defined standard or test method.
When comparing products, buyers should verify that the values are measured using comparable methods.
Comparing numbers from different test methods without understanding the methodology can lead to misleading conclusions.
Whiteness and brightness can be important in applications where the visual appearance of the final product matters.
These characteristics can be relevant to paints, coatings, plastics, paper, inks, and other products.
However, manufacturers should review the specific test method used to report whiteness.
A technical data sheet may use a particular colour measurement system or testing procedure.
Therefore, buyers should compare like-for-like measurements whenever possible.
Surface treatment is an important distinction between many titanium dioxide grades.
Commercial grades may use treatments involving materials such as aluminium, silicon, zirconium, or combinations of these. Tayca's published specifications, for example, identify different treatment combinations across its rutile grades.
Surface treatment can influence properties such as:
Manufacturers should therefore select surface-treated grades according to their intended application.
pH can also appear on titanium dioxide technical data sheets.
Commercial specifications commonly provide a pH range for an aqueous suspension.
For example, several Tayca grades list pH ranges around 6.0–8.5 depending on the grade.
While pH may not be the primary selection factor for every application, it can be useful when evaluating compatibility with a particular formulation or process.
Residue on sieve provides information about the amount of coarse material remaining after a specified screening process.
Lower residue values can be relevant where manufacturers require controlled particle characteristics and good dispersion.
Published technical specifications show that different titanium dioxide grades can have different sieve-residue limits.
When comparing suppliers, buyers should check both the numerical value and the test method used.
Specific gravity and bulk density are different measurements, but both may be relevant to industrial handling and formulation.
Specific gravity can affect how the pigment behaves on a mass or volume basis within a formulation.
Bulk density can influence:
Buyers should make sure they understand whether a supplier is reporting specific gravity, bulk density, or another density measurement.
A common procurement mistake is to focus on a single number.
For example:
Higher TiO2 content = better product
This is not necessarily true.
Similarly:
Smaller particle size = better product
This also cannot be assumed universally.
The practical performance of titanium dioxide depends on multiple properties working together.
A better comparison considers the complete technical profile.
Salford supports industrial buyers looking for dependable raw material sourcing solutions.
For businesses evaluating titanium dioxide, the selection process should begin with the intended application and required technical characteristics.
Salford can support buyers in evaluating their requirements for imported titanium dioxide and selecting products according to factors such as grade, application, quantity, specifications, and procurement needs.
For recurring requirements, businesses can also discuss bulk supply expectations and establish clearer product specifications before placing repeat orders.
The objective should be to create a dependable supply relationship rather than treating every titanium dioxide purchase as an isolated transaction.
Comparing titanium dioxide grades requires more than looking at the product name or purchase price.
Manufacturers should examine the technical data sheet and evaluate crystal structure, TiO2 content, particle size, surface treatment, oil absorption, tinting strength, whiteness, pH, residue, density, dispersion, and other relevant properties.
The importance of each specification depends on the intended application.
A titanium dioxide grade suitable for one paint, plastic, masterbatch, ink, paper, or coating application may not be the best choice for another.
Manufacturers should therefore begin with their specific production requirements and then compare grades according to the technical characteristics that matter most.
Application testing can provide additional confidence before committing to large-volume procurement.
For businesses sourcing imported titanium dioxide, working with an experienced Titanium Dioxide Importer can simplify product evaluation, documentation, bulk procurement, and supply planning.
Salford supports industrial buyers with raw material sourcing solutions and helps businesses evaluate titanium dioxide according to application, technical requirements, quantity, and procurement needs.
By comparing technical specifications carefully and considering actual manufacturing performance, businesses can select titanium dioxide grades more confidently and establish a more reliable raw material procurement strategy.
Important specifications can include crystal structure, TiO2 content, particle size, surface treatment, oil absorption, tinting strength, whiteness, pH, residue on sieve, density, dispersion, and application suitability.
Rutile and anatase are different crystal forms of titanium dioxide. Their characteristics and typical application suitability can differ, so manufacturers should select the form according to their specific requirements.
No. TiO2 content is only one specification. Particle size, surface treatment, dispersion, tinting strength, oil absorption, and other characteristics can also affect performance.
Particle size can influence properties such as dispersion, opacity, tinting behaviour, and finished-product appearance. The appropriate range depends on the application.
Surface treatment can influence dispersion, durability, weather resistance, gloss, and compatibility with particular formulations.
