THE BMM APPROACH
More than mineral loading. Performance in the compound.
A rubber-grade talc is not defined by fineness alone. Mineral character, lamellarity, particle-size distribution and dispersion behaviour all influence the result.
We begin with the elastomer system and the compounder’s target. This helps align source selection and processing with mixing, dimensional, surface and production requirements.
RUBBER APPLICATIONS
Start with the compound. Refine by specification.
Share where the talc enters your system and what the finished rubber product needs to achieve.
Moulded components

Rubber-Grade Talc
Dedicated Rubber Grade
BM S2
Controlled Mineral Grade for Rubber Compounds
BM S2 is a controlled rubber-grade talc developed for consistent incorporation and dependable mineral performance. Its particle characteristics and lamellar mineral structure support processing consistency, compound body and surface uniformity across selected moulded, extruded and general industrial rubber applications.
Grade-specific specifications and technical documentation are available on enquiry.
Request BM S2 Technical DataBM S2 is Bharat Mines’ dedicated rubber-grade talc, developed for consistent incorporation and functional mineral performance across selected rubber and elastomer compounds. Grade suitability should be confirmed against the customer’s formulation, processing conditions and finished-product requirements.
GRADE SELECTION
Is BM S2 suitable for your compound?
BM S2 can be considered where a controlled talc grade is required for general-purpose mineral filling, consistent processing and uniform finished-product characteristics. Suitability depends on the elastomer system, loading level, processing conditions and target properties.

| Evaluation Area | What to Consider |
|---|---|
| Elastomer System | Confirm compatibility with the applicable natural or synthetic rubber formulation and other compound ingredients. |
| Functional Requirement | Assess whether the formulation requires mineral filling, compound body, dimensional stability, processing consistency or surface uniformity. |
| Loading & Processing | Evaluate the proposed dosage under actual mixing, extrusion, calendering or moulding conditions. |
| Finished Properties | Validate hardness, modulus, tensile strength, elongation, compression set, surface finish and other application-specific requirements. |
BM S2 should be evaluated through laboratory or production-scale compound trials. Final dosage and suitability remain dependent on the complete formulation, processing conditions and required finished-product performance.
PERFORMANCE FRAMEWORK
Choose the grade around what the compound must do.
The correct starting point depends on the complete formulation, loading, process and required balance of properties.
Processing consistency
Controlled sourcing and classification can support repeatable incorporation and compound preparation.
Dimensional control
Grade selection considers shrinkage, stability and the dimensional targets of the finished rubber part.
Modulus & dimensional contribution
In an appropriately formulated compound, talc may contribute to stiffness, hardness and dimensional behaviour. Final performance depends on elastomer type, loading, dispersion and the complete formulation.
Surface uniformity
Particle profile and dispersion can influence the surface consistency of moulded and extruded rubber products.
Final compound performance depends on the complete formulation and process. Grade selection should be confirmed by customer evaluation.
PARTICLE PROFILE
Grade-specific particle control for repeatable compound evaluation.
Nominal mesh alone does not fully define a rubber-grade talc. Particle-size distribution, mineral morphology and dispersion behaviour provide a more useful basis for evaluating incorporation and compound performance.
SediGraph III particle-size analysis using X-ray monitored gravity sedimentation and Stokes’ law calculation.
The particle-size curve and values shown are representative results from a talc sample measured by SediGraph. They are not a contractual product specification; values may vary by product and batch and may not be directly comparable with results obtained using other particle-size measurement methods.
Plate-like structure. A controlled starting point.
Talc’s layered mineral structure produces plate-like particles. In a suitable rubber formulation, morphology and particle profile can influence incorporation, reinforcement, dimensional behaviour and surface character.
Mineralogy alone does not determine performance. Elastomer compatibility, loading, dispersion, additives and processing must be considered together.

Consistency begins before micronisation.
Application First
Share the elastomer, loading, process, present grade and the performance result you need.
Mineral Character
We consider mineral character, particle-size distribution, chemical profile, moisture and raw-material consistency—not mesh alone.
Particle Engineering
Micronisation and classification are aligned with dispersion and processing requirements.
Compound Evaluation
Shortlisted grades should be validated in the customer’s complete formulation before commercial adoption.

COMMON QUESTIONS
Before you request a grade.
-
Please share the elastomer system, target loading, mixing and moulding process, current grade or specification, required properties, approximate volume and destination. This gives us a practical starting point for discussion.
-
Talc may contribute to dimensional behaviour in a suitable formulation, but the result depends on the elastomer, loading, particle characteristics, additives and processing conditions. Customer-side validation is essential.
-
Yes. Candidate grades can be shortlisted for customer-side trials after reviewing the formulation, process and target performance.
-
Product specifications, TDS, SDS and batch-specific COA support can be discussed for the selected product and destination.
