Polyethylene terephthalate in the industry is also known by the acronym “PET”! This material can be used to produce a variety of impact-resistant products. In the following, we want to see the most important applications of Iran polyethylene terephthalate.

What are the applications of polyethylene terephthalate in the industry?

The applications of polyethylene terephthalates in various industries are very diverse. One of the most important applications of polyethylene terephthalate is the production of plastic bottles. We know that plastic bottles have interesting advantages over glass bottles. These bottles are easy to carry and very easy to use.

In addition, these substances are produced daily around the world. Another important application of polyethylene terephthalate is the production of durable parts in the automotive industry. In addition, this material can be used in the aircraft industry. In the automotive industry, the need for a flexible, polyester material is always felt; For this purpose, polyethylene terephthalate can be used to produce all kinds of car interior parts as well as its engine.

In general, polyethylene terephthalate is one of the most important polyesters that has a wide variety of applications in the textile industry. This material is simple, but there are special points to using it. One of the most important points of using polyethylene terephthalate is the disposal and recycling of its waste.

This material produces a lot of waste due to daily production. For this purpose, we must recycle polyethylene terephthalate by special methods. PET is also used in the production of building insulation; This material is water-resistant and can also be used to produce moisture-proof sheets. In addition, it can be used to produce electrical insulation.

Because pet waste is produced all over the world, it must be recycled well. In the following, we want to see the importance of recycling polyethylene terephthalate.

Why should we recycle polyethylene terephthalate?

Due to the very diverse production of polyethylene terephthalate in global industries, this material must be recycled on an industrial scale; Because there are so many pet contaminants around the world! On average, millions of PET plastic bottles are produced every day. These bottles should not be discarded or placed outdoors.

The use of PET can increase environmental pollution. It should be noted that this material can not be easily recycled! There are several different ways to recycle polyethylene terephthalate that can cause more pollution! For this reason, it is very important to study the recycling of polyethylene terephthalate. This material must be well recycled and reused.

But we want to introduce the best way to recycle polyethylene terephthalate in the following

What is the best way to recycle PET?

The best way to recycle polyethylene terephthalate is to use the enzymatic method. This way, there is no need to burn the material or bury it! It is enough to easily perform the decomposition reactions of polyethylene terephthalates using different enzymes and knowing the polymeric materials.

Enzymatic methods are very important; Because different enzymes are used to recycle polyethylene terephthalate, each of which will increase the risk of using PET. But if this material is recycled well, the production of Iranian polyethylene terephthalate products will be done more quickly.

One of the most important ways to increase the efficiency of enzymes is to increase the ambient temperature. The increase in ambient temperature is done up to about 70 to 80 degrees Celsius, but it should be noted that this increase should not damage the enzymes.

In this regard, there are different ways to increase the resistance of enzymes to heat. In the following, we want to introduce ways to increase the thermal resistance of enzymes.

1. The use of surfactants is very effective!

The addition of surfactants to enzymes increases the flexibility of the material. It should be noted that these substances must be mixed with enzymes according to the standard. This will increase the heat.

Surfactants were used in various experiments; These materials make the relationship between the hydrophilic and hydrophobic phases in solutions significantly better! This allows a variety of enzymes to function well in the reaction medium. Also, it speeds up the reaction process of recycling polyethylene terephthalate enzymatically.

2. Combine enzymes!

Each of the enzymes used for PET enzyme recycling has special properties. Concomitant use of these enzymes may be the best way to increase the thermal stability of polyethylene terephthalate.

In addition, this enables these enzymes to enhance the synergistic effect of each other to get the best results from recycling. One of the most important points in the composition of enzymes is that we should not mix these enzymes antagonistically; Because this will reduce the effect of each enzyme.

The combination of enzymes adds the properties of all these enzymes to the environment. In this environment we are going to recycle polyethylene terephthalate; So in addition to increasing the temperature, we can combine the enzymes to increase the enzymatic resistance of these materials.

3. Use of ultrasonic waves; One of the most important ways to increase the thermal stability of polyethylene terephthalate

The use of ultrasonic waves makes the enzymatic recycling of polyethylene terephthalate faster. This reduces the test time, thus reducing damage to the enzymes at high temperatures at 70 to 80 ° C; Because the test time is much shorter.

Therefore, a significant increase in the thermal stability of polyethylene terephthalate can be seen using this method. It should be noted that ultrasonic waves should not be applied too much to the reaction medium, this will change the polymer structure of polyethylene terephthalate.

4. Use of engineered enzymes

Advances in science have led to enzymes being engineered using a variety of methods. This allows the enzymes to acquire extraordinary genetics. Changes in the genetic structure of enzymes are done using modern methods.

This will make the enzymes more resistant to heat in the process of recycling polyethylene terephthalate enzymatically. This in turn reduces the reaction time significantly and increases the reaction efficiency.

Summary of a study of thermal stability of polyethylene terephthalate

In this article from PETROPROVIDERS, we have mentioned the most important ways to increase the thermal stability of polyethylene terephthalate. We know that polyethylene terephthalate is one of the most important polyesters in the industry that has many different uses. This material can be used to produce a variety of plastic products as well as a variety of durable materials.

It should be noted that the use of polyethylene terephthalate on an industrial scale increases environmental pollution. For this reason, we must pay close attention to the recycling of polyethylene terephthalate.

Pet recycling is done in different ways, the best way to do it is the enzymatic method. In the enzymatic method, the efficiency of the reaction can be increased by increasing the temperature.
