Calcium carbonate has a wide range of applications in the plastic industry. It can be used as a filler, modifier, or functional additive, improving the physical properties of plastics (such as increasing hardness, rigidity, and heat resistance), reducing production costs, and imparting special functions to plastics. Below are some key applications of calcium carbonate in the plastic industry:

1. Filler

The primary application of calcium carbonate is as a filler. It increases the volume of plastic products, thereby reducing production costs.

The addition of calcium carbonate can also improve certain physical properties of plastics, such as increasing hardness, rigidity, and heat resistance.

The type and particle size of calcium carbonate will affect its application effect in plastics.

Common calcium carbonate fillers include ground calcium carbonate (GCC) and precipitated calcium carbonate (PCC).

2. Modifier

Calcium carbonate can serve as a modifier for plastics, improving specific properties such as impact strength and weather resistance.

Adding calcium carbonate can also improve the processing performance of plastics, such as reducing melt index and increasing fluidity.

Surface-treated calcium carbonate has better compatibility with plastic matrices, enhancing the modification effect.

3. Functional Additive

In certain plastic products, calcium carbonate can be used as a functional additive, such as a flame retardant or antistatic agent.

Adding calcium carbonate can impart special functions to plastic products, such as flame resistance and antistatic properties.

4. Application Fields

Calcium carbonate is widely used in various plastic products, such as:

• PVC Products: Including pipes, profiles, sheets, etc.

• PE/PP Products: Including injection-molded parts, extruded parts, films, containers, pipes, etc.

• ABS Products: Including housings, components, etc.

• Engineering Plastics: Including automotive parts, electronics, and electrical components.

Diamond Quantum's CCR calcium carbonate is highly refined and enhances the strength of plastic products. The surface of CCR is treated with fatty acids to increase compatibility with plastic materials.
