Mineral Additive Selection for EVA and NBR Footwear Foams
If you formulate EVA or NBR footwear foam, a talc purchase should be tied to your cell structure, density and mechanical targets.
Relia's talc candidates can be reviewed against that brief.
- System
- EVA or NBR formulation
- Mineral
- Identity and particle data
- Function
- Flexibility and required mechanical limits

From Your Requirement to a Defined Grade
Relia manufactures industrial talc materials in China through its own factories.
Our talc enquiry should name the polymer system and the result your footwear material needs. Share the current mineral, foaming system and accepted density or flexibility range with Relia. The candidate grade needs a clear particle specification, while your matched foam trial establishes its practical contribution.

The Foam Target
FT-AR992 and FT-AYB92P are listed with 1500–3000 mesh designations for different foam enquiries. The broader EVA/NBR foaming-talc entry provides another route. We first connect each proposed grade to your polymer, foaming method and finished-sole requirements, rather than assign a cell-size result from mesh alone.

Foaming Talc Options for Shoe Materials
| Review area | Listed data and acceptance basis | Use in your selection |
|---|---|---|
| FT-AR992 · 6584 | The title names shoe soles and NBR foam with 1500–3000 mesh. Confirm the offered grade's measured distribution. | Use the same particle measurement basis, then review dispersion and the result in your process. |
| FT-AYB92P · 6585 | This entry names shoe soles and EPE foam with 1500–3000 mesh. Keep it distinct from similarly named coarser listings. | Use the same particle measurement basis, then review dispersion and the result in your process. |
| Foaming talc · 6574 | The entry spans EVA, NBR, latex and insulation enquiries. Select the actual polymer-specific proposal. | Use this item to define the candidate and the evidence needed for your application. |
| Foam acceptance | Set density, cell distribution, hardness, resilience and relevant compression criteria for the finished material. | Use your required finished-product result as the acceptance point for the candidate. |
Compare the Product Candidates
Use these listed candidates to start a grade-specific discussion with us.
Cells and Flexibility Together
Compare candidates in a fixed polymer and foaming system, with mixing and cure history recorded. Review the cell structure together with density and the required finished-sole properties. A visually fine cell structure is only useful if the material also meets the application's mechanical requirements.

Foam-grade wording
Does not qualify every polymer.
One property
Does not describe the whole foam.
New system
Needs its own comparison.
Mineral Selection, Milling and Classification
Talc preparation involves size reduction and classification of a naturally platy mineral. Particle condition and dispersion can influence how it behaves in a foaming formulation, but they do not establish a universal cell-size or density improvement. Keep the powder data with the mixing and foaming history so the trial can locate the source of a changed result.
Define the mineral grade
Talc proposals need their own composition and relevant impurity requirements.
Reduce and classify
Milling and size separation create the particle fraction supplied to the formulation.
Retain the physical description
Platy character, particle distribution and powder condition are separate from a use-related grade title.
Compare in the actual system
Keep those material data with the formulation and process that produce the foam or compound.
- Particles
- Request a distribution relevant to the application instead of relying on mesh alone.
- Condition
- Identify supplied moisture or agglomeration information where it matters.
- Finished material
- Judge the foam or component under matched preparation and test conditions.
A System-Specific Approval
Keep the accepted foam specimen, additive sample and grade identity connected. We discuss supply within that tested scope. A different polymer or foaming process then has a clear reason for another evaluation.

Continue Your Material Selection
If you buy calcium carbonate for an industrial rubber compound, match the filler to the rubber, cure system and finished-part limits.
If talc is being considered for latex or insulation foam, qualify it within that specific foam system.
If you are evaluating calcium sulfate whiskers in rubber or polymers, confirm both the calcium-sulfate phase and the actual whisker form.
