PVC is a special player in the plastics recycling process. It is often found mixed with other types of plastic scrap, like HDPE, PP, PET, and PE film scrap.

Because it is different from other types of plastic, it needs to be separated so that it can be recycled properly.

In this blog post, we will discuss why PVC needs to be separated from other plastics, how it is done, and what can be done with the PVC once it has been separated.

What Is PVC?

Preparing PVC Pellets for Processing Environments

PVC, or polyvinyl chloride, is a type of plastic that is used in a variety of applications. It is often used in construction because it is strong and durable.

PVC can be found in pipes, windows, siding, and more.

Because it is so versatile, PVC is one of the most widely used types of plastic.

The Importance Of Separating PVC Scrap In The Recycling Process.

PVC is a special player in the plastics recycling process. We have to separate out PVC scrap from HDPE, PP, PET, and PE film plastic scrap mixed with it. Why is it necessary to separate PVC?

As we mentioned before, PVC is a different type of plastic than the others. HDPE, PP, and PET can all be recycled together, but PVC needs to be separated first.

The reason for this is that PVC is not as easy to recycle as the other types of plastic,

If the raw material is adulterated with PVC in the hot-melt granulation process, it will have a bad effect on the quality of the product.

The color will be darker, the transparency will be reduced, and the strength will be decreased.

The main reason to recycle PVC is that it contains harmful chemicals. When mixed with other plastics, these chemicals can leach out and contaminate the other recyclables.

If your plastic recycling line is for the production of food packaging, such as water bottles or food containers, this will have an impact on the health of your customers, which in turn will affect the reputation of your brand and even expose you to prosecution.

Why PVC Is Different From Other Types Of Plastic?

PVC is a special kind of plastic because it has a high chlorine content. This chlorine makes PVC resistant to degradation, meaning it doesn’t break down easily in the environment.

For this reason, it’s important to separate PVC from other types of plastic scrap before recycling.

The physical properties of PVC make it easy to identify and separate from other plastics. PVC is stiff and has a high density, so it sinks in the water while other plastics float.

This makes it easy to separate PVC from HDPE, PP, PET, and PE film plastic scrap using a water separation process.

How Is PVC Scrap Separated From Other Plastics?

PVC can be separated from other plastics using a variety of methods. One common method is to use a gravity separator.

A gravity separator is a machine that uses the different densities of the materials to separate them. The heavier materials will sink to the bottom while the lighter materials float to the top.

Which Machines Can Separate PVC In A Plastic Recycling Line?

There are a few different types of machines that can be used to separate PVC from other plastics.

One type is a manual separation table. This is a table with water running down it. The operator manually sorts the materials by density, with the PVC sinking to the bottom and the lighter plastics floating to the top.

Another type of machine that can be used is an air separator. This machine uses a stream of air to separate the materials by density. The PVC will sink down while the lighter plastics are blown up into a collection chamber.

What Can Be Done With The Separated PVC?

Once separated, PVC can be recycled into new products like pipes, siding, flooring,

PVC, or polyvinyl chloride, is a type of plastic that is used in a variety of applications. It is often used in piping, siding, and flooring.

PVC can be recycled into new products, making it a sustainable choice for many applications.

The separated PVC can be sold to companies that make new PVC products from recycled material.

This allows the PVC to be reused and reduces the amount of waste that ends up in landfills. Selling the PVC is also a good choice because it provides a revenue stream for the recycling facility.
