Titanium Dioxide for Masterbatch

Define the two-stage system

Treat the pigment, carrier-based concentrate and receiving-resin article as separate evaluation objects. Record what you know for each stage:

• carrier resin identity and Grade;
• receiving resin identity and Grade;
• TiO2 fraction in the concentrate and in the final material;
• concentrate preparation, equipment and process conditions;
• let-down and conversion route;
• final specimen, geometry or thickness;
• reference material; and
• required optical, colour, mechanical, ageing or other end-use endpoints.

If an input is unknown, state that it is unknown and identify who can supply it. A shared polymer-family name alone does not make two systems equivalent.

Read each observation for the question it answers

A published LLDPE study varied carrier and concentrate-preparation conditions before producing cast films at controlled final pigment content and thickness. It measured flow, morphology, optical response and ageing separately. This is a useful example of the two stages and complementary evidence, not a carrier, loading or formulation prescription for another system.

When observations agree, check that their stage, specimen, method and endpoint bases also align. When they differ, inspect those bases and collect the missing comparable evidence before assigning a cause.

Ask each document the right question

Manufacturer product pages illustrate why these roles should remain separate. The current Chemours Ti-Pure R-350 page presents application positioning and links product information, SDS and TDS resources separately. The current KRONOS 2220 page marks some product-characteristic values as typical. A page position or one field's status does not turn every value into a lot result or an independent application comparison.

Start with the records that answer your current question. A TDS can support early Grade screening, while an SDS provides safety information. Add a relevant lot CoA once a lot is identified, and use application data when a tested system needs to be assessed. Record any missing document or context for later verification, and keep each conclusion within the document or trial that supports it.

Compare economics after the accepted endpoint

Powder price and nominal loading alone do not establish cost in use. Compare economics only after the candidate systems reach the same accepted final functional endpoint in the declared masterbatch and receiving-resin system.

Then define the inputs you will compare: actual consumption, delivered cost, accepted yield, energy and time, losses, and allocated testing or change costs. Keep currency, date or period, terms and destination comparable. If the technical endpoint or current operating and commercial inputs are missing, request those data before calculating a result.

Prepare your request

Tell us the carrier and receiving resin where known, concentrate and final TiO2 fractions, preparation and conversion route, final specimen, target endpoints, comparison reference, documents already reviewed and the next unresolved question. State unknown conditions rather than guessing them.

• Request Technical Documents when you know one Product Grade and need one or more document types. Submit a separate request for another Grade. The team reviews document availability and applicable scope.
• Request a Sample with a known Grade or an unknown-Grade selection, your masterbatch application, destination and test objective. Submission starts a review; any arrangement is confirmed separately.
• Discuss Your Masterbatch Application with a known lead Grade or Not sure / Need help. Tell us your masterbatch application, required or estimated quantity in metric tonnes, destination and any other context you already know. If several Grades are under consideration, list the others in Additional Requirements.

After an RFQ is submitted, the team reviews the requirements and details and contacts you using the information provided.
