Product category: Calcium carbonate
Mikron'S Calcium Carbonate grades are branded as TURKCARB®in general, let manufactures to produce high quality products in many applications. Calcite (CaCO3) found in nature in marble, limestone and chalk forms with different crystal shapes.Depending on the amount of impurities, whiteness parameters may fluctuate. Deviation of Silicate (SiO2 ) contents will also effect hardness values of the material. TURKCARB®high brigthness and negligible abrasion values features the quality of TURKCARB raw material quality level. TURKCARB®grades are very fine GCC (Ground Calcium Carbonate) which is also featured with fine particle size distribution. Starting from 90% fraction under 2 microns fineness till 100 microns median size, Mikron'S able to produce outstanding products to offer optimum solutions. Ultrafine grades of TURKCARB® will offer superior surface finish solutions to paint, paper and plastics industries. Overseparated TURKCARB® grades are another class of product Group in which surface coating is not feasible, to decrease the oil absorption values. Decreasing the oil absorption of calcium carbonate will bring so many advantages to processors to decrease binder absorption, decreasing of manufacturing costs while using more calcium carbonate in the recipes.
Usage of Coated TURKCARB® grades have many advantages in plastics and coating.
Day by day,more these processors are shifting to coated grades due to;
Low surface energy,
High Hydrophobic effect,
To get easy and homogenious dispersion,
Low oil, DOP and polymer absorption,
Increase in mechanical properties.
Increase chemical and mechanical strength,
To get high quality surface and high brightness,
TURKCARB® UFC has same particle shape characteristics as TURKCARB® UF, whereas it's surface treated with suitable hydrofobic agents which enables to keep high gloss values in solvent based paints during long period of time. Since surface treatment changes alkalinity of natural Calcium Carbonate, it also keeps oil acids in alkyd resins away from Calcium Carbonate surface. If this contact occurs, Calcium carbonate reacts with acids to form CO2 gas, that forms bubbles which create matting in paint film during storage on shelves after production.
The FILMPLUS range of fine coated calcium carbonates are the leading mineral product in breathable film applications for the hygiene, medical and roofing markets.
TURKCARB® UFC, TURKCARB® 100C and TURKCARB®95C goods which are especially prefered in plastic profile sector and has low abrasivity of extruders with good surface. In order to get more bright and high resistance goods we use advanced technology developed in the world.
Precipitated Calcium Carbonate is obtained from Limestone calcination over 900°C. Limestone is burned, to form lime from which pcc is obtained by consequtive chemicals reactions under pressure.Since chemical reactions are concerned,impurities are eliminated by outstanding chemical process control to form a ideal whiteness,particle size and crystal shape. PCC crystals have uniform crystal shape and particle size distribution, not like Ground Calcium Carbonate.
PCC production technique can be illustrated as follows ; * CaCO3 CaO + CO2 (calcination Process) * CaO + H2O Ca(OH)2 (milk of lime) * Ca(OH)2 + CO2 CaCO3 + H2O (Precipitation)
Following the modern production technologies and adapting these into reality , MikronS started to manufacture micronised calcium carbonate and Talc in 2004. MikronS has became the important player in the region in short period of time by fulfiling ;
Constructing the the biggest factory of Turkey producing micronised and coated Calcium Carbonate and Talc. Thanks to the Research & Development and Production & Development works developed within its infra structure, the producer of many generic products , which became the generic brand of the sector, The first company on the market, by breaking new grounds in 2004. The company bringing into the sector the innovations and facilities with the application tech niques developed in the applications, The brand preferred with priority in the segments, thanks to its product range outstanding with its fineness and alternatives, trend-setting products.
Our Vision; To be a leading brand in the region , that moves ahead by its team in the journey of perfection, that contributes to the society and the world.
Our Mission; By focusing systematic point of view,MikronS will try to create technical solutions and approaches that are continuously renewed and are trend-setting; to add value to the materials , to our business partners and to our sector.
