Food Grade refers to materials, additives, or chemicals that are safe for human consumption and meet stringent purity and safety standards set by food regulatory authorities such as the U.S. Food and Drug Administration (FDA), European Food Safety Authority (EFSA), or Codex Alimentarius. These substances are specifically approved for use in food production, processing, packaging, or preparation, ensuring they do not pose health risks when ingested.  Food-grade materials must be free from harmful contaminants, such as heavy metals, toxic residues, or pathogenic microorganisms, and they often comply with specifications like Food Chemical Codex (FCC) for purity. Examples include preservatives, flavorings, colorants, emulsifiers, and packaging materials (e.g., food-safe plastics or lubricants for machinery). 

Calcium Carbonate (Uncoated)

Calcium Carbonate (uncoated) is a naturally occurring mineral compound composed primarily of calcium, carbon, and oxygen with the chemical formula CaCO₃. It appears as a fine white powder or granules, widely used as a filler, pigment, and functional additive across various industries. The uncoated form means the calcium carbonate particles are not surface-treated, retaining their natural properties. It is valued for its high brightness, whiteness, and excellent compressibility. Uncoated calcium carbonate is used to enhance opacity, improve processing, and reduce costs in plastics, paints, coatings, adhesives, rubber, paper, and construction materials.

Calcium Carbonate Heavy

Calcium Carbonate Heavy is a high-density, finely ground, natural mineral primarily composed of calcium carbonate (CaCO₃). Known for its higher bulk density compared to regular grades, this filler is widely used in applications requiring enhanced weight, opacity, and strength. It is commonly employed as a functional filler and extender in industries such as plastics, paints, coatings, adhesives, rubber, paper, and construction materials. Its inert nature, whiteness, and particle size distribution make it suitable for improving mechanical properties and surface finish, while also offering cost efficiency by replacing more expensive raw materials.

Titanium Dioxide

Titanium Dioxide (TiO₂) is a naturally occurring oxide of titanium known for its exceptional brightness and high refractive index. It is one of the most widely used white pigments in the world due to its excellent opacity, UV resistance, and chemical stability. Available in various crystalline forms—mainly rutile and anatase—it is used across numerous industries including paints, plastics, paper, cosmetics, and food. Industrial grades are often surface-treated to enhance performance in specific applications.
