What is the Use of Precipitated Calcium Carbonate in PVC Pipes

October 14, 2022 posted by Shreekarni

Have you ever wondered if precipitated calcium carbonate is a versatile product?

Does it have any other uses besides calcium carbonate powder for paper, paint, and rubber industry?

However, PCC finds its application as calcium carbonate powder for PVC pipes.

Why PCC is considered for PVC pipes? What benefits does it offer? Let us learn more about it.

What are the Benefits of Using PVC Pipes?

The full form of PVC is Polyvinyl Chloride. It is made from a mix of plastic (poly) and vinyl components.

PVC (PolyVinyl Chloride) pipes have been the top choice for irrigation and sewage pipes because of their high strength and durability.

It further offers a smooth flow of water and less friction due to the smooth surface. They are lightweight and recyclable. Thus, the installation process becomes easy.

Since PVC pipes do not rust easily, they are the top choice for water systems. PVC pipes also offer a cost-effective alternative to copper or cast iron pipes.

How is Precipitated Calcium Carbonate used in PVC pipe manufacturing?

Impact modifiers are quite expensive. They increase the cost of PVC pipe manufacturing.

Adding calcium carbonate powder up to 2-3 microns fulfils the impact specifications in large-diameter PVC pipes.

However, it is difficult to meet the impact specifications in smaller-diameter PVC pipes. This issue is resolved by using 1-2 microns of fine calcium carbonate powder.

The filler property of high-quality calcium carbonate enhances the PS properties and enhances rigidity at room temperatures.

Benefits of Using PCC for PVC Pipes

PCC is known for its filler and whitening properties. But it offers more benefits than that.

It enhances the processing properties of PVC pipes by increasing the compounding performance and making the mixture homogeneous.
Ultrafine precipitated calcium carbonate powder for PVC pipes does not affect the hoop strength of the pipe.
It increases the stiffness of the polymer mix.
As the particle size reduces, the impact resistance increases. Therefore, high speed and force water would not affect the pipe strength.
It gives a shine to the PVC pipe.
It increases the tensile strength of PVC pipe.
Using calcium carbonate or coated calcium carbonate for PVC pipes increases severity, which allows the PVC pipes to even function at high temperatures.

Pro Tip- Avoid adding high volumes of calcium carbonate powder in PVC pipes. This can adversely affect the tensile strength.

Other Applications of Precipitated Calcium Carbonate

Calcium Carbonate powder for PVC pipes is one of its applications. Besides this, precipitated calcium carbonate has many other applications.

Calcium Carbonate powder for paint industry

It is used as a filler and adds shine to the paints.

Calcium Carbonate powder for paper industry

It enhances the opaqueness and whiteness of the paper. However, it should be used in limited amounts, or it can destroy the binding strength.

Calcium Carbonate powder for Rubber industry

It enhances the heat resistance, hardness, and stability of rubber.

Major Takeaways

Calcium Carbonate powder finds its uses in different industries. Precipitated calcium carbonate has many advantages that enhance the lustre, smoothness, and strength of PVC pipes.
