Plastic raw material in Delhi


Plastic raw material in Delhi Calcium carbonate filler Masterbatch is a white additive that gives special properties as well as a high level of whiteness to the plastic masterbatch and at the same time, it is a cost-saving product. Calcium Carbonate is one of the most standard plastic fillers masterbatches and constitutes about half of the total fillers used in the Plastic raw material in India at Tephra Polymers.

What is calcium carbonate filler? What characteristics do they have?

Tephra Polymers Plastic raw material in Delhi Calcium carbonate filler (CaCO3 filler, also known as Calcium Carbonate Masterbatch) has always been the most commonly used filler in the Plastic raw material manufacturer in Delhi and its position has never failed over the years despite the processing and adjusting technologies have been researched and functional more and more over years. So what features of calcium carbonate filler made Plastic raw material suppliers in Delhi Reasons contributing to the current position of calcium carbonate filler in the plastics industry.

Not only in the Plastic raw material manufacturer in Delhi, but calcium carbonate filler masterbatch also functions as a filler that is widely used in other industries and production in Plastic raw material manufacturers in Delhi. The reason CaCO3 is favored is that firstly, this material source is extremely ample and available in many areas and regions around the world. The abundance of reserves allows the exploitation of this substance to be unrestricted, resulting in low cost and stable supply for a long time Plastic raw material suppliers in Delhi.

Secondly, calcium carbonate filler has moderate hardness, is not too soft but still not too solid, making it easy to method and the process can grind into powder or into larger sizes.

Finally, CaCO3 is chemically suitable for combination with many other substances, so manufacturers can combine this substance with many different types of plastic raw materials and polymers. In short, calcium carbonate filler brings a lot of economic value to producers, both in quantity, production capacity, and product quality.

What effect does calcium carbonate filler benefit the plastics industry?

When Plastic raw material in Delhi used as a plastic additive masterbatch, in addition to exchanging a part of raw materials and helping Plastic raw material manufacturer in Delhi to reduce production costs as much as possible, CaCO3 also functions by helping plastic masterbatch products increase hardness, durability, adhesion as well as impact resistance. In addition, the aesthetics of the end masterbatch product also increased significantly since CaCO3 improves and adjusts the glossiness and opacity of the product’s surface (by adjusting the amount of calcium carbonate filler added to the plastic). At the same time, adding CaCO3 to plastic products also increases their surface printability Plastic raw material supplier.

The physical properties of calcium carbonate filler

Pure calcium carbonate is in solid form (usually in the form of fine powder), , odorless and has white color with melting point temperature ranging from 800 to 1400oC. Their molecular weight is 100,087 g/mol.

Chemical properties of calcium carbonate

The reason that Plastic raw material in Delhi can broadly use calcium carbonate filler in Plastic raw material in India is that the chemical properties of it (CaCO3) and the plastic in its connotation are not changed when mixed together with many plastic types and other additives. In addition, calcium carbonate is also insoluble in water, stable under normal temperature conditions and only reacts with some strong acids (such as HCl), medium (as sulfamic) or weak acids (acetic, citric, phosphoric, lactic, sorbic). Thanks to these properties, Tephra Polymers Plastic raw material in Delhi generated from calcium carbonate filler masterbatch will be applied in a wide range of fields, including those that required the assurance of user’s safety such as the food and beverage Plastic raw material in India.

Types of common calcium carbonate used to produce calcium carbonate filler

Tephra Polymers is Plastic raw material manufacturer in Delhi use calcium carbonate filler. Tephra  Polymers have used it in two forms: coated CaCO3 and uncoated CaCO3. Coated CaCO3 is mostly exploited from limestone or white marble mines with high clearness and only differs from uncoated CaCO3 at the opinion that they are coated with fatty acids (stearic acid) and bonding agent (Titanate Coupling Agent) on their surface.

In overall, the physical and chemical properties of these two types of calcium carbonate filler masterbatch are not significantly different. Most physical properties such as whiteness, brightness, moisture, weight, pH, etc. do not consist of any differences between 2 types. The only exclusion 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 Plastic raw material supplier:

  • 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%

Applications of calcium carbonate filler in the plastics industry

Tephra Polymers Plastic raw material in Delhi , calcium carbonate filler is used in mixture with a wide variability of plastics masterbatch, from rigid plastic, and flexible plastic to thermoplastic. Applications of calcium carbonate 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. Applications produced through the injection molding methods with this type of masterbatch include food wraps used in supermarkets, shopping bags, garbage bags, agricultural films, etc.
