Marble Chips 1-2.5 MM are finely crushed calcium carbonate (CaCO3) particles, primarily used as a filler in plastics, paints, adhesives, and construction materials for enhanced durability and texture. This calcium carbonate also serves as a raw material in cement production and glass manufacturing, and in copper and lead smelting and other metal refining processes. This high-purity, inert mineral also serves as a pH regulator, abrasive, and decorative aggregate in various industrial and artistic applications. Catalogue details: CAS 471-34-1, molecular weight 100.09, particle size range 1–2.5 mm, non-hazardous (no signal word), and stable at ambient storage conditions. Molekula supplies Marble Chips 1-2.5 MM from research to bulk quantities with full documentation and ISO 9001:2015 traceability.
