| Factor | 100 Mesh | 200 Mesh | 325 Mesh | 400 Mesh | 800 Mesh (optional) |
|---|---|---|---|---|---|
| Average Particle Size | Coarsest (~150 μm) | Medium-coarse (~75 μm) | Fine (~45 μm) | Finer (~38 μm) | Ultra-fine (~18 μm) |
| Filling Performance | Excellent for bulk filling | Very good | Good, more refined | Good, precision filling | Best for high-spec formulations |
| Surface Area | Lowest | Low-moderate | Moderate | Moderate-high | Highest |
| Flowability | Excellent | Good | Good | Moderate | Lower (finer powders pack tighter) |
| Processing Characteristics | Easy to handle in bulk, low dusting | Easy handling | Requires slightly more dispersion control | Needs good mixing/dispersion | Requires precision processing equipment |
| Typical Applications | Construction, dry mortar, asphalt filler | Mortar, plasters, mid-grade fillers | Adhesives, sealants, paints | Plastics, rubber compounding | Polymer masterbatch, fine industrial formulations |
| Cost Efficiency | Most economical | Economical | Moderate | Moderate-higher | Highest cost |
In short: 100 Mesh offers the best cost-to-volume ratio for high-tonnage, bulk-filling applications where fine surface finish is not the priority.
As a bulk filler in dry mortar formulations, 100 Mesh calcium carbonate improves batch volume, workability, and formulation consistency, helping producers control material costs without compromising mix stability.
The coarse, uniform particle distribution provides reliable filler performance in tile adhesive formulations, supporting stable rheology and consistent open time across production batches.
Used as a mineral filler in cement-based products, 100 Mesh enhances bulk properties and improves overall production efficiency in high-volume manufacturing.
Well suited for plasters, renders, wall putty, and repair compounds, where coarse particle size supports body and texture without adding unnecessary cost.
Acts as a stable mineral filler in asphalt mixes, contributing consistent particle size that supports mix stability and durability in road construction applications.
Serves as a natural calcium source for soil applications, supporting soil conditioning and pH balancing in agricultural formulations.
Provides a high-purity calcium source suitable for feed formulations, subject to applicable regional regulations and customer-specific specifications.
Choose 100 Mesh if:
Consider 200 Mesh instead if: A finer texture is needed while maintaining good filling performance.
Consider 325 Mesh instead if: Better dispersion and smoother finished products are required.
Consider 400 Mesh instead if: Plastic or rubber processing requires finer mineral particles.
Consider 800 Mesh instead if: High-quality polymer compounds or finer industrial formulations are needed.
What industries commonly use 100 Mesh uncoated calcium carbonate? It is widely used in construction materials, dry mortar, tile adhesives, cement-based products, asphalt production, agriculture, and animal feed manufacturing.
What is the average particle size of 100 Mesh? 100 Mesh corresponds to a nominal particle size of approximately 150 microns, with a D50 typically in the 30–45 micron range depending on the batch.
Is this grade suitable for dry mortar production? Yes. Its coarse, uniform particle size makes it well suited as a bulk filler in dry mortar formulations, improving volume and workability.
Can it be used in tile adhesive formulations? Yes. 100 Mesh provides stable filler performance and consistent particle distribution suitable for tile adhesive production.
Is it suitable for agriculture and fertilizers? Yes. It serves as a natural calcium source and can support soil conditioning in agricultural applications.
Can it be used in animal feed applications? Yes, subject to applicable regional regulations and customer-specific feed formulation requirements.
How does 100 Mesh compare with 200 Mesh? 100 Mesh is coarser and more economical, best suited for bulk filling. 200 Mesh offers a finer texture while still maintaining good filling performance, suitable for applications requiring a smoother finish.
What packaging options are available? We offer 25 kg bags, jumbo bags (500 kg, 1000 kg, 1200 kg), and palletized packaging, with OEM and private label options available.
Can Arosha Powder provide OEM packaging? Yes. We offer custom bag printing and private label packaging tailored to buyer branding and market requirements.
Which countries do you export to? Arosha Powder currently exports to more than 20 countries worldwide, supported by established international logistics partnerships.
