Calcium Carbonate + PE

ATR-312, a high-quality rutile type titanium dioxide, is a versatile material that has a wide range of applications in various industries.

Characteristics

Cost Reduction: Calcium carbonate is less expensive than polyethylene resin. Incorporating calcium carbonate into PE formulations can significantly reduce material costs, making the composite material more economical for various applications.
Improved Stiffness and Rigidity: Calcium carbonate acts as a filler and reinforcing agent in PE, increasing the stiffness and rigidity of the composite material. This enhanced stiffness is beneficial for applications requiring structural integrity and dimensional stability.
Reduced Density: Calcium carbonate has a lower density than PE resin. By adding calcium carbonate to PE formulations, the density of the composite material can be reduced while maintaining volume. This can lead to weight reduction in the final product, which is advantageous in applications where lightweight materials are desired.

4. Enhanced Dimensional Stability: The presence of calcium carbonate in PE can help minimize shrinkage and warpage during processing, improving the dimensional stability of molded or extruded parts. This is particularly important in applications requiring tight tolerances and precise geometries.
5. Opacifying Effect: Calcium carbonate can improve the opacity and whiteness of PE formulations. This opacifying effect is beneficial in applications where aesthetics are important, such as in packaging or consumer goods.

Filler in Plastics: Calcium carbonate is commonly used as a filler in plastic materials, including polyethylene. It can improve stiffness, impact resistance, and dimensional stability while reducing costs.
Construction Materials: Calcium carbonate and PE can be combined to create composite materials used in construction, such as decking, fencing, and siding. These materials benefit from the strength of PE and the reinforcing properties of calcium carbonate.
Paper Coating: In the paper industry, calcium carbonate is used as a coating pigment to improve brightness, opacity, and printability. Adding PE to the coating formulation can enhance water resistance and durability.
Adhesives and Sealants: Calcium carbonate-filled PE can be used in the formulation of adhesives and sealants for various applications, including bonding and sealing in construction, automotive, and packaging industries.
