What is CaCO₃ Masterbatch (Calpet, Calcium Carbonate Masterbatch)?

 

Hello.

In this article, we will explore CaCO₃ Masterbatch.

It is commonly referred to as Calpet and is also known as Calcium Carbonate Masterbatch.

CaCO₃ Masterbatch (Calpet Masterbatch) is an additive used to reduce costs and enhance the strength and hardness of plastic products. It is widely applied in packaging materials, pipes, and injection-molded products to improve processability and durability.

CaCo3 Masterbatch

CaCO₃ Masterbatch is primarily used in plastic manufacturing. It is added in small amounts during plastic processing to improve the physical properties of the final product or to impart specific functions. CaCO₃ Masterbatch contains a high concentration of calcium carbonate (CaCO₃) and is mainly utilized to enhance the properties of plastic products, reduce costs, and provide environmental benefits.

The manufacturing process of CaCO₃ Masterbatch

1. Limestone, marble, and other calcium carbonate-rich minerals are mined.

2. The mined limestone and marble are crushed.

3. The CaCO₃ powder obtained from step 2 is mixed with resins such as PE and PP.

4. The mixed materials are extruded, cooled, and cut to complete the CaCO₃ Masterbatch.

Key Features and Advantages of CaCO₃ Masterbatch

1. Cost Reduction

: CaCO₃ Masterbatch is a cost-effective material. Adding CaCO₃ to polymer resins (e.g., PE, PP) helps lower production costs.

2. Property Enhancement

: CaCO₃ Masterbatch increases the strength of plastics, particularly improving hardness and rigidity. This contributes to enhanced durability of the final product.

3. Improved Processability

: The addition of CaCO₃ Masterbatch enhances the molding and processing characteristics of plastics. For example, it helps reduce thermal deformation and provides a more uniform surface quality.

4. Optical Properties

: Adding CaCO₃ Masterbatch to plastics increases opacity, making the product’s appearance more vivid or meeting specific visual requirements.

*Disadvantages

1. Excessive use may reduce the flexibility of plastics or decrease impact resistance.

2. Since CaCO₃ increases opacity, it may not be suitable for transparent plastic products.
