Micronized Calcium Carbonate Powder — Uncoated
Mesh 200 Calcium Carbonate — Uncoated Powder
Raw-material selection is a strategic decision, not a checkbox. MAD KOOHZAD's mesh 200 calcium carbonate is engineered as the deliberate balance point between process cost and finished-product performance — a precise particle-size distribution (74 microns), excellent dispersion, and controlled oil absorption that keep quality consistent from your first batch to your hundredth.
The Sweet Spot of Cost and Performance
Delivers the best yield at the lowest landed cost compared with finer meshes (which cost more) and coarser meshes (which give up mechanical performance).
Ready-Made Dispersion
A 74-micron particle size disperses cleanly across resins and polymers on standard mixing equipment — no specialty dispersing agents, no agglomeration headaches.
Smarter TiO₂ Economics
A whiteness index above 95% lets you cut expensive titanium-dioxide loading without visibly losing hiding power or final gloss.
The Workhorse Grade
From UPVC profile and pipe extrusion to construction paint and adhesives, mesh 200's balanced profile covers the widest span of industries — one grade to stock instead of several.
A Full Technical Breakdown of Mesh 200: From the Spec Sheet to the Production Floor
This section goes past the datasheet numbers and into what mesh 200 calcium carbonate actually does for your line. Every parameter below maps to a specific outcome — a cost saved, a defect avoided, a property gained — so you can make the call with full technical confidence, not just a supplier's word.
More Than an Additive: Mesh 200 as a Strategic Input
At MAD KOOHZAD, we don't ship calcium carbonate as an undifferentiated commodity — we engineer a repeatable input for your process. A poorly sourced or inconsistent filler carries hidden costs: mechanical properties that drift batch to batch, visible color shift, faster tooling wear, and — eventually — a customer complaint that costs more than the material ever saved. Guaranteed purity and tightly controlled particle size on every shipment of our mesh 200 remove that variability from the equation. This isn't a line item to minimize; it's the input that keeps your own product's quality boring and predictable, batch after batch — which is exactly what industrial buyers want from a supplier relationship.
Reading the Data Sheet: What Each Number Actually Buys You
A technical data sheet isn't a formality — it's the input variables for your own formulation's success. Here's what matters most on mesh 200's TDS and why:
1. Purity above 98.5% — Impurities like silica (SiO₂) or iron oxide (Fe₂O₃) accelerate equipment wear, discolor light and white formulations, and can trigger unwanted side reactions in your compound. High base purity means maximum chemical stability and the fewest surprises on your process line.
2. Oil absorption of 18–22 g/100g — This number is a direct line to your finished cost. The lower a filler's oil absorption, the less expensive resin, lubricant, and plasticizer you need to hit the same rheology. Controlled oil absorption on this grade is money saved in every batch, not just a nice-to-have spec.
3. Precise 74-micron particle size — This is mesh 200's real "sweet spot." Fine enough to disperse well and leave a smooth finished surface, coarse enough that mixing stays simple and cheap on standard equipment. That combination gets you the mechanical properties you need without the process overhead finer grades demand.
Mesh 200 in the Field: Solving Real Problems Across Industries
Mesh 200 isn't a one-size-fits-all filler — it's a precise fit for specific, named problems in the following industries:
Plastics and compounding (PVC, UPVC) — The challenge: maximizing impact strength and rigidity in profiles and pipe while keeping production cost under control. MAD KOOHZAD's answer: mesh 200 acts as a reinforcing filler, filling voids in the polymer matrix and raising mechanical strength. Its clean dispersion prevents the stress-concentration points that start cracks. What that means for you: a tougher finished product at a more competitive price, with lower raw-material cost per unit.
Paint and construction coatings — The challenge: raising hiding power while cutting consumption of titanium dioxide, the single most expensive line item in most paint formulations. MAD KOOHZAD's answer: with high whiteness and an optimized particle-size distribution, mesh 200 works as an ideal extender. By spacing titanium particles apart, it raises their individual efficiency, letting you replace a meaningful share of TiO₂ with calcium carbonate. What that means for you: a real drop in cost per kilogram of paint, with hiding power and coverage held steady.
Mesh 200 — Technical FAQ
How does the "reduced TiO₂ consumption" claim for mesh 200 actually work, and where's the limit?
It comes down to what's called the spacing effect. Expensive titanium-dioxide particles tend to agglomerate in a formulation, losing hiding-power efficiency as they clump. Mesh 200 particles act as spacers — they sit between TiO₂ particles and distribute them optimally through the matrix, so each titanium particle does its full share of light scattering. The limit: this effect holds up to an optimal loading point. Push calcium carbonate past that point and you'll start losing gloss and abrasion resistance. Our technical team can help you find that point for your specific formulation rather than guessing.
Does adding mesh 200 to a PVC compound reduce impact strength?
No — used correctly, it doesn't just avoid reducing impact strength, it can improve it. Mesh 200's controlled particle size lets it act as a stress-transfer agent: when the finished part takes an impact, the calcium-carbonate particles distribute that energy across the polymer matrix instead of letting it concentrate at one point and start a crack. The condition for this to work is full dispersion with no agglomerates — which is exactly what our processing guarantees.
Do I need special equipment or expensive dispersing agents to fully disperse mesh 200 in a resin or polymer?
This is actually one of mesh 200's biggest practical advantages: it's easy to disperse. Unlike much finer meshes (mesh 800 or 1200, for example), which have higher surface energy and agglomerate readily — needing high-shear mixers or dispersing agents to break up — mesh 200 disperses well in ordinary industrial mixing equipment. That keeps your process cost and complexity down.
What's the effect of mesh 200 on the final product's surface finish?
Mesh 200 is a deliberate middle ground. For the vast majority of applications — pipe, structural profile, matte and satin paints, general industrial parts — the finished surface will be fully uniform with no visible defect. If your target is very high gloss, or extremely thin plastic film (under roughly 50 microns), the 74-micron particle size can show through slightly in the final finish. For those specific cases, a finer grade such as mesh 400 or 800 is the better fit.
