US MASTERBATCH has selected high-quality ultrafine calcium carbonate and additives to produce high concentration particles via twin-screw pelletizers.
Generally speaking, people wouldn’t directly apply calcium carbonate CaCO3 into plastics before the treatment of surface activation in order to optimize its performance. Meanwhile, according to the requirement of Blow Film and its performance, US MASTERBATCH has selected high-quality ultrafine calcium carbonate and additives to produce high concentration particles via twin-screw pelletizers.
The main source of supply of calcium carbonate filler masterbatch comes from limestone quarries. In nature, CaCO3 exists under 3 main forms of crystals: calcite, aragonite and vaterite. Among three, calcite, thanks to its relevancy of crystal structure, is the most commonly used type because they have the most commercial applications. Through well dispersion and fully kneading, we could finally provide customers high concentration calcium carbonate masterbatch with 70-80% dispersibility. These PP and PE CaCO3 Filler masterbatch are also well known as calcium carbonate Filler Masterbatch.
2 types of common calcium carbonate CaCO3 are used to produce calcium carbonate CaCO3 filler masterbatch. In industries that use calcium carbonate filler, they are used in two forms: coated CaCO3 and uncoated CaCO3. Coated CaCO3 is mainly exploited from limestone or white marble mines with high purity and only differs from uncoated CaCO3 at the point that they are coated with fatty acids (stearic acid) and bonding agent (Titanate Coupling Agent) on their surface.
In general, the physical and chemical properties of these two types of calcium carbonate CaCO3 Filler masterbatch are not significantly different. Most physical properties such as whiteness, brightness, humidity, weight, pH, etc. do not consist of any differences between the 2 types. The only exception is oil absorption in which uncoated CaCO3 is superior (30.08 g/100g compared with coated CaCO3 only 18.71 g/100g). The following are indicators that show the physical properties of calcium carbonate:
Whiteness: 98% minimum Brightness: 96% minimum Humidity: 0.2% maximum Gravity: 2.7 g/cm3 Specific surface area: 4.23 – 4.72 m2/g In addition to their chemical composition, in addition to the presence of stearic acid, there is no difference: Calcium carbonate (CaCO3): 98.5% Silicon Oxide (SiO2): 0.03% Magnesium Oxide (MgO): 0.02% Aluminum Oxide (Al2O3): 0.02% Iron Oxide (Fe2O3): 0.02
Working as fillers replacing partial plastics to reduce costs and increase productivity, further to achieve better economic benefits
With white pellet appearance, it is ideal to apply with all colors of products and to reduce the usage of white pigment.
The high compatibility increases soft and comfortable level of product surface and maintains better luster
EXCELLENT INK ABSORPTION
Upgrading the quality, inked force, printability, and whitewash of foam products; providing better breathability of film products.
Automatic metering would effectively reduce dusts and improve surroundings.
Enhancing impact resistance, flexural strength, and dimensional stability of products; texture and weight of finished products are upgraded as well.
REDUCING DEFECT RATE- INCREASE OUTPUT LOW MAINTANENCE
Particle shapes and sizes are uniform due to chemical precipitation process. Damages to extruder screws would be improved because of its low silica content. Operation without temperature setting would also reduce power consumption on account of low viscosity.
In production, calcium carbonate CaCO3 filler Masterbatch is used in combination with a wide variety of plastics, from rigid plastic, flexible plastic to thermoplastic. Applications of calcium carbonate CaCO3 Filler masterbatch are numerous. If you pay attention, you will notice a lot of things around us, which we use and contact daily are made from CaCO3 filler Masterbatch. Applications generated through the blown film includes PE shopping bags, Garbage bags, all kinds of Pe. Industrial films, Packaging materials, and containers with many reasons widely used
