Calcite Powder is extensively utilized as a filler in the manufacturing of plastics owing to its low oil absorption, high dispersibility, smooth surface finish, high impact resistance, easy processing, unmatched dimensional stability, and compatibility with other complex polymers and organic additives.

Currently, CaCO3 filler is widely used in plastic production because of the following benefits:

• Limestone has a natural white color, so CaCO3 fillers give the finished product high whiteness without the use of bleach, whiteners, or colorants.
• CaCO3 is abundant in nature, easy to exploit, and cost-effective. Plastic fillers can partially replace primary plastic, helping to reduce production costs. CaCO3 filler also has good thermal conductivity, which saves energy and shortens the production process.
• Environmentally friendly properties help prevent evaporation and reduce temperature in factories.
• CaCO3 filler helps increase properties of finished products such as hardness, surface gloss, flexural resistance, impact resistance, and more.
• Easily mixed with additives and colorants.
