Kaolin is a hydrated aluminum silicate crystalline mineral formed over many millions of years by the hydrothermal decomposition of granite rocks. It is a white soft mineral composed primarily of Kaolinite mineral having a chemical composition of Al2O3.2SiO2.2H2O with minor amounts of quartz, feldspar, and sheet silicate minerals (mica, illite, smectite).
Hard and soft clays are characterized by their fine particle size, platy or lamellar particle shape, and chemically inertness. Clays having fine particle sizes are described as hard clay. Phyllosilicates being a subgroup of silicate minerals that has typically less than 2µm in diameter. The combination of platy shape and fine particle size results in improved processibility, improved reinforcement, tensile strength, abrasion, and tear strength.
After mining the above mineral ore is dressed, dried, pulverized, air-floated, water-washed (levitated), calcined, and surface modified. As per the application, the grades are selected by the end-user.

Industries We Serve:
1. RUBBER HOSES, EVA FOOTWEAR & ALLIED APPLICATION:
Clay is a non-black mineral filler used in rubber and EVA Polymers having the largest volume after Carbon Black filler. It owes this opportunity to a combination of low cost, low to moderate reinforcement, and processing benefits. Due to its low cost, the economy in compound cost is attained. The price of polymer and other additive chemicals, fillers are rather high.
The clay ore is produced from various deposits of mines. Ore is dried, pulverized, and refined by either air-floatation or water washed to remove impurities and to produce clay in the desired particle size range. There are many types of clays but in Rubber it is termed as:
1) Soft Clays, or
2) Hard Clays- terms derived from relative rubber hardness produced.
Durometer hardness is the usual starting point for a guide in selecting clay loading. A rule of thumb in many elastomers is to use 5-6 phr of hard clay and 7-8 phr of soft clay for each point in hardness above the base hardness of the unfilled compound. When clay is used to replace other fillers, it is recommended that the replacement be based on equal volumes. Refinements in the formulation to accommodate processing and hardness can be made by a rubber technologist by the addition of process oil.
Thus, clays can be formulated to rather high loadings in most elastomers, with soft clays allowing somewhat higher loadings than hard clays. Process aids are frequently used to improve the dispersion and mechanical properties like tensile strength etc. The main factor to consider in adding clay to most formulations is its reduction of cure rate. Reduction in cure rate requires the addition of an activator. In certain cases, a combination of Carbon Black with Hard Clays increases mechanical properties like modulus and tensile strength while reducing compression set and maintaining lower compound cost.
Clay is used in almost all types of rubber products including automotive hose, flooring tile compounds, EVA FOOTWEAR. Since it remains inert it is naturally nonabrasive, and its neutral pH value shall have additional process advantages though few applications prefer acidic pH value and some alkaline pH value. MYBIA MANIFOLD PRIVATE LIMITED provides Clay in different pH values suitable to the user industry.
Today the principal non-black fillers are clays, Whiting and calcium carbonate, & Silicas. Clays are used to the greatest extend, followed by calcium carbonate and silica. There are three properties important for the users. These properties are particle size, specific gravity, and price. The specific gravity of a filler affects the molded product’s final weight, which may be important in few applications. MYBIA MANIFOLD provides LOW & UNIFORM PARTICLE SIZE products to the benefit of its application as Semi reinforcing filler. The reinforcement of rubber, dependent on particle size, also has a wide range. The term “reinforcement” applies to improvement in mechanical durability, usually related to tensile strength, tear strength, and abrasion resistance.
2. PAINT & INKS:
Clay has been used for painting application by the people of the ancient world as white, plate-shaped material because of its earthy nature, its fineness, its opacity, and its easy dispersibility in water.
In paint application, Kaolins are used in Hydrous and Calcined Forms. It can improve the optical, mechanical, and rheological properties of paint.
Hydrous Kaolins are used in water and solvent-based paints in distempers, interior and exterior paints, primers, and undercoats. Calcined Kaolins are widely used in satin and matt paints where they can deliver increased opacity, whiteness, and scrub resistance. Kaolin is particularly useful nowadays as a partial replacement for TiO2 pigment.
In practice it is found that there are no specified standard specifications of Kaolin published by big manufacturing plants, rather it is mentioned “to match standard” that is already in their use. The quality is determined by the degree of its brightness, Whiteness, Opacity, hiding power, gloss, water demand, oil absorption, particle size, specific gravity, and viscosity.
MYBIA MANIFOLD offers Hydrous Kaolin, which is pulverized grades, air-floated grades, and water-washed (Levigated) grades as well as Calcined kaolins.
When formulated in paint, fine Kaolin act as a functional extender of TiO2, reducing formulation cost and improving rheology. Some of our product grades do not offer so much potential to extend TiO2 but do enhance the dry film properties of primers and undercoats and some grades offer paint makers the possibility to extend TiO2 in solvent-based gloss paints processed using high-speed dissolvers rather than bead mills traditionally associated with this type of paint- cutting processing time and increasing efficiency.
Recent trends are using Hi-Brite Clays in manufacturing Semigloss, Full gloss of Oil-based Paints, Coatings and inks. It improves coverage area, scattering, flowability. Good quality kaolins keep the paint in suspension and its sediment resistance.
China Clay is an essential constituent of Ceramics. It is used by almost all manufacturers worldwide in Electrical porcelain, Fine China & dinnerware, Floor and Wall tiles, Roof tiles, Pottery, Sanitary ware, Tableware, and other engineering products. The properties important for the use of China Clay in Ceramics are –Plastic Properties, drying properties, Firing properties, Firing Color, Electrical properties such as conductivity, dielectric content, etc.
Our clay permits the product to be easily deformed under stress without rupturing and retains the shape produced when stress is removed. Due to low water of plasticity, it does not require intense forming pressure to withstand handling/drying, and the Green Strength is better. The Firing properties are excellent to produce a super white finish. The processed clay is free from grits and all metallic impurities. The particle size is very low and even keeps drying shrinkage in desired parameters.
Our Clay is most porous, and platelets are very fine and smooth, closely squeezes together to let the water of plasticity evaporate easily without any cracks.
Good Vitrification property is the important constituent of our Clay. Vitrification is the process of becoming glasslike. Although Clay products never become vitrified or glasslike, it is necessary that the Clay become HARD (almost vitrified) at a reasonable temperature. Any substance will melt at some temperature. Our clay holds better its shape and does not sag or slump in the primary melting stage which sets it apart from other clays.
Kaolin provides smooth surfaces, dimensional stability, and resistance to chemical attack. It also conceals fiber reinforcement patterns and reduces shrinkage and cracking during polymer compounding and shape forming.
When it is surface modified it is used as a functional filler and rheological modifier to improve mechanical, electrical, and thermal properties. Kaolin is used in PVC wire & cables, High Voltage insulating compounds, engineering plastics, specialty films, automotive parts based on engineering thermoplastics.
Ultrafine and best purity products are recommended in plastics.
Our value-added products have been developed to offer user-friendly applications that shall be made available on request.
