Minerls
Filler materials (or minerals) are particles added to resin or binders (plastics, composites, concrete) that can improve specific properties, make the product cheaper, or a mixture of both. The two largest segments for filler material use are elastomers and plastics. Worldwide, more than 53 million tons of fillers are used every year in application areas such as paper, plastics, rubber, paints & coatings, construction, cosmetics & pharmaceuticals, fibers, foods, printing, adhesives, and sealants. These filler materials can affect the tensile strength, toughness, heat resistance, colour, clarity etc. in the application where used.
The most common type of filler materials used in the world are ground calcium carbonate (GCC), precipitated calcium carbonate (PCC), kaolin, talc, and carbon black. Most of the filler materials used in plastics are minerals which include mostly GCC, PCC, Calcite, Calcium Chloride, and dolomite.
At,
Mahavir Group, we are one of the largest filler mineral distributors in the country, handling about 3000 MT every month.
Calcium Carbonate
Calcium Carbonate is one of the most essential & popular filler minerals in the plastic industry. As an important element in plastic compounds, it helps by improving the base properties of the plastic by adding stiffness to the polymer matrix and improving impact resistance as particle sizes become smaller. It also helps decrease surface energy and provides opacity and surface gloss, which improves the surface finish of the products.
Calcium Chloride
Calcium chloride is an important chemical used in different industries including petroleum refineries. It is also used as antifreeze and as an anti-dust for manufacturing brine. It finds extensive use as refrigeration brine and in roads and for freeze proofing of bulk shipment of materials such as coal, iron and other minerals. It is used in PVC for rigid pipe socketing and acts as a softening agent. Another use of calcium chloride is in the manufacturing of inter-locking tiles where it acts both as a filler as well as drying agent.
At, Mahavir Group, we have two types of calcium chloride available, powder form & liquid form.
Dolomite
Dolomite is a double carbonate rock with composition of calcium & magnesium. Chemically & structurally, it is similar to calcite with half the calcium ions replaced by magnesium. Dolomite can be used in building materials, ceramics, glass and refractory materials, chemical industry, agriculture, environmental protection, energy saving and other fields.
Dolomite powder is pure white, insoluble in water, with a relative density of 2.5, stable chemical properties, and a slippery feel. As a plastic filler, dolomite powder can improve the hardness, fire resistance, acid and alkali resistance, electrical insulation and dimensional stability of the product. In rubber, it can increase the volume of the rubber, improve the processability of the rubber, play a role of semi-reinforcement or reinforcement.
Calcite
Calcite is the one of the most common minerals. Calcite is the principal constituent of limestone and marble. These rocks are extremely common and make up a significant portion of Earth’s crust. They serve as one of the largest carbon repositories on our planet. The properties of calcite make it one of the most widely used minerals. It is used as a construction material, abrasive, agricultural soil treatment, construction aggregate, pigment, pharmaceutical and more. It has more uses than almost any other mineral.
In the paper industry, it is used as filler and coating material in most paper-producing industries to harden or smoothen, as necessary. Calcite allows rapid paper drying in the paper-making process due to its oil absorption feature. In the plastics industry, it acts as the primary filling material in plastic factories as it helps maintain the thickness everywhere. It is used in paint industry as a pigment material to prevent steel wear, increasing water and chemical resistance.
Precipitated Calcium Carbonate
Calcium carbonates have long been recognized as useful additives for thermoplastics and particularly in PVC for many applications. Ground calcium carbonate (GCC) is generally used as a filler with an interesting ratio performance/price.
Precipitated Calcium Carbonate (PCC),
however, exhibits a much smaller particle size. It is much more than a filler. The specific structure and granulometry of PCC allow it to fulfil additional functions, such as: Processing aid, Impact modification (reinforcer) & Weather-resistant Agent. PCC is a filler used in many applications, like papers, plastics, rubbers, paints, drugs and so on.
At, Mahavir Group, we deal in PCC manufactured by Kunal Calcium as their authorised dealer.
