Steps of making expanded polystyrene

Expanded polystyrene and extruded polystyrene differences

Expanded polystyrene is made of white polystyrene beads and is used for packaging, insulation, and other items. It is made of styrene and pentane. EPS is made from polystyrene beads, but extruded polystyrene is made from the crystalline beads of this material. Water can destroy the insulating properties of EPS, but extruded polystyrene is durable and resistant to environmental factors. For this reason, this type of polystyrene is used in construction.

How to make expanded polystyrene

EPS is designed and manufactured in three stages: pre-expansion, growth, stability, and molding. Polystyrene is made from crude petroleum products. Expanded polystyrene is made with pentane foam solvent. Polystyrene beads are pre-foamed at temperatures above 90 ° C. This temperature causes the pre-foam solvent to evaporate and swell 20-50 times its original size. Polystyrene beads are stored for 6-12 hours to return to pre-changed condition.

Extruded polystyrene

Extruded polystyrene is produced by the extrusion process. Plastic resin and other materials are melted and poured into molds and taken out of the mold after cooling and freezing. This type of polystyrene is the best insulation and is resistant to moisture and static load. In some cases, it is even used as building insulation.

Expanded polystyrene and extruded polystyrene differences

The first difference is the production method of expanded and extruded polystyrene from polystyrene beads. EPS is strong, and has light insulation. Extruded polystyrene is also durable and strong.

EPS is made from a thermoplastic material made from polystyrene granules. While extruded polystyrene is made of polystyrene crystals. Expanded polystyrene has the least negative impact on the environment compared to extruded polystyrene.

Definition

EPS is a thermoplastic material made from polystyrene beads, but extruded polystyrene is made from polystyrene crystals.

Expanded polystyrene and extruded polystyrene differences

Expanded polystyrene and extruded polystyrene differences

Raw material

Expanded polystyrene is made from solid grains of polystyrene, while extruded polystyrene is made from crystals. In the production of extruded polystyrene, resin and other materials are used, but in expanded polystyrene, the grains of this material is used.

Production Process

The heating of gas-containing polystyrene beads produces expanded polystyrene. But extruded polystyrene is made by removing the liquid molten polystyrene mold, which is cooled and thickened in the molds.

EPS and XPS

EPS and XPS

Impact on the environment

Expanded polystyrene has had the least negative impact on the environment. On the contrary, extruded polystyrene has the most negative impact and destroys the environment.

Introduction of applications

Expanded and extruded polystyrene are both used as insulation in building panels. They range in size from 50 to 152 cm and have similar performance. With these panels, energy loss inside the building can be prevented.

Energy conservation inside the building unit is the most important goal defined for expanded and extruded polystyrene. However, the use of each will be determined according to the different applications. The production method of each of these materials will affect how they are used in the long run.

Production goals

Water absorption

As water penetrates the expanded polystyrene, the insulation function is lost. This use is true in underground and false ceilings. Being aware of the temperature below freezing allows you to use expanded polystyrene properly. Increasing and decreasing the temperature will create a vacuum between the expanded polystyrene beads, and as a result, their insulating properties will be lost. But extruded polystyrene has a closed structure and will not be negatively affected by temperature changes and environmental factors such as water and wind.

XPS

XPS

Heat conduction

The thermal conductivity of extruded polystyrene is very low compared to expanded polystyrene. Air transfers heat, and since the molecular structure of extruded polystyrene is more interconnected than that of EPS, extruded polystyrene is perfectly suited for this use.

Compressive strength

The strength of EPS is very low compared to extruded polystyrene. The stronger the foam, the stronger its strength and resistance to pressure.

Conclusion

Expanded polystyrene is made from polystyrene beads, but extruded polystyrene is made from the crystalline beads of this material. Water can destroy the insulating properties of expanded polystyrene, but extruded polystyrene is durable and resistant to environmental factors. For this reason, this type of polystyrene is used in construction.

The molecular structure of extruded polystyrene is closed and therefore has high compressive strength and has advantages over expanded polystyrene.

methods of polystyrene recycling

Different methods of polystyrene recycling

Polystyrene is one of the most well-known thermoplastic materials with a transfer temperature above 100 ° C. This substance is difficult to decompose and therefore can pollute the environment. Many needs can be met by foam recycling.

The reason for reducing the volume of recycling

Recycling polystyrene is done in different ways and today many recycling companies do not have the necessary government incentives to do so. Therefore, a small amount of polystyrene is recovered and polystyrene foam is seen in small amounts and densities in the waste. Recycling is not cost-effective in many ways. That’s why recovery companies get a small amount of polystyrene. But recycling polystyrene foam is a business that has a lot of potentials and can be developed and expanded.

The recycling industry is developing and it is necessary to make the necessary investments in this industry to increase the amount of recycling from 30 kg to 400 kg. New methods can be found for polystyrene recycling so that it can be done faster and with more cost-effective methods.

Conclusion

By recycling polystyrene by melting, smelting, and molding methods, new products, and goods can be produced. This chemical decomposes over more than 500 years; So recycling is better in many ways, recycling methods are not cost-effective at the moment. It is necessary to make the necessary investments in this industry so that recovery companies are willing to do so.

Dangers of polystyrene

Most important Dangers of polystyrene

So far, little has been said about the dangers of polystyrene, and the dangers of plastics and rubber have always been mentioned in articles. Most food containers are designed and manufactured with polystyrene. This chemical is prepared by combining BENZENE and ethylene and by binding to polymer chains and carbon dioxide. Many people are not aware of the dangers of polystyrene; Most products used in daily life are made from this chemical.

Recognize the dangers of polystyrene

Harm to human health

All the materials used to make polystyrene are harmful to humans and carcinogenic. Even exposure to these substances can cause cancer. Toxic substances enter the human body in food packaging containers. The heat of food causes more toxic substances to penetrate the human body.

Harm to human health the environment

These toxins enter the environment and pollute it. Since polystyrene does not decompose, the negative impact of this material on the environment is very high. Recycling this material is expensive and it is not cost-effective. Polystyrene is lightweight and easily enters and contaminates running water.

This chemical can enter and endanger their lives, even where single-celled organisms such as plankton live.

Collecting this material from the environment is a big challenge and its recycling is costly. There are very few centers in the world that do this! This material only needs to be disposed of properly so as not to harm the environment.

Harm to human health the environment

Harm to human health the environment

Polystyrene decomposes in at least 500 years!

Because polystyrene is made from several chemicals, it decomposes over 500 years and is harmful to the environment during decomposition. The volume of plastic waste is 25-30% of other waste. By using less plastic goods, this cycle of destruction can be broken and the environment kept healthy.

Decomposition of high impact polystyrene (HIPS) and general-purpose polystyrene (GPPS) also takes more than 500 years. This substance causes harmful damage to the environment during this period.

Penetration of polystyrene toxins through disposable packaged foods

This chemical contains toxic substances derived from benzene and styrene compounds. Both are carcinogenic and harmful to the human body. Hot foods placed in packing containers break down toxins and inject them into human blood.

Any food that is placed in disposable packaging containers is contaminated with these toxic substances and enters the human body. It is recommended to avoid consuming any kind of drink in a disposable glass. Avoid packaging fatty foods with these containers.

Avoid placing disposable closed containers in the microwave

The health authorities of many countries have asked people not to put disposable packaging containers in the microwave because the toxins of these chemicals will seep into the food when heated. The use of disposable packaging containers is banned in the United States, Canada, and the European Union. These types of dishes are not safe from microwave heat.

Impact on global warming dangers of polystyrene

According to studies by the World Environment Organization, plastic waste is the fifth most polluting factor in the environment. This material is the second most polluting factor after aluminum and increases greenhouse gases.

Polystyrene products are produced from petroleum derivatives. Extruded polystyrene is made of hydrochlorofluorocarbon, which destroys the ozone layer and affects global warming. The rate of ozone depletion is related to the number of hydrochlorofluorocarbons, which affect global warming 1,000 times more than carbon dioxide.

Avoid burning plastic materials

Combustion of these substances releases carbon monoxide and harms the environment and human health.

Pollution of water resources among dangers of polystyrene

The US Environmental Protection Agency estimated there were 46,000 plastic wastes per square meter in 2006. The lightness and buoyancy properties of polystyrene allow it to penetrate environmental resources, especially the earth’s water resources and cause environmental pollution. This chemical enters the seas and oceans through rivers. Plastic waste from cities is the largest source of pollution on the planet’s water resources. Any kind of pollution of water resources harms human life and tourism. In addition to polluting the earth’s water resources, polystyrene also kills aquatic organisms.

According to a study by the US Environmental Protection Agency, 162 species of seabirds have been fed plastic, which is a shocking statistic about the negative effects of this chemical. That is why the use of polystyrene is banned in the developed countries of the world.

Conclusion

Polystyrene is made from benzene and ethylene, which are harmful to human health and the environment. These substances are carcinogenic and threaten human health. Polystyrene takes 500 years to decompose, and during those 500 years, it damages the environment.

In addition to environmental pollution, the entry of this substance into water resources also causes the death of aquatic organisms. Burning plastic materials releases carbon monoxide, which is also harmful to humans and the environment.

Today, the people and governments of first-world countries are aware of these dangers, and the use of this substance is prohibited in these countries.
