The production of polystyrene granules has different stages. When making polystyrene granules in the related industry, they combine ethylene and gasoline to produce this material. Next, the granules are made based on a highly specialized process of hydrogenated gasoline and styrene.
After this step, the styrene that is provided is polymerized using oxygen during the polymerization process. Finally, polystyrene is made. These polystyrenes are available in various industries and are available to consumers after becoming granules.
You may be interested to know that polystyrene granules are known as a type of polymer that comes in granular form. These materials are a form of polymer. The reason for using different types of polystyrene granules is simplicity and ease of production.
If we want to provide polystyrenes in powder form for the production of various products, a large amount of this powder will be lost. It also contaminates the workshop space and can cause respiratory problems. There will be no problems with converting polystyrenes into granules.
The use of polystyrene granules will prevent these problems. The structure of the devices that are designed to produce different types of plastics is formed by considering the use of raw materials in the form of granules. To produce polystyrene-based products, the granules are first melted.
Application of polystyrene granules
Application of polystyrene granules
One of the methods of supplying polystyrene is in the form of granules. This material is used as raw material in some manufacturing industries. Polystyrene granules have a chemical structure and are made of hydrocarbons and hydrogen and have a relatively high resistance to high temperatures.
Most polystyrene granules are obtained from recycled materials on the market. The use of recycled polystyrene materials for the production of granules causes the polystyrene waste to be put back into production. This reduces the waste and also increases the cleanliness of the environment. Another advantage of this is the reduction of raw material costs for various industries.
There are several types of polystyrene granules
Polystyrene granule factories produce them in various forms and with different qualities based on the needs of different industries. Based on their structure, polystyrene granules are each suitable for industry.
General Purpose Polystyrene Granules:
It is one of the examples of polystyrene granules that are known as crystals in the Iranian market. General Purpose polystyrene granules have properties such as temperature stability and high durability.
This type of granule has high impact resistance. This granule has many applications, the most important of which is its use as cooling insulation and the manufacture of various types of sports equipment, various types of toys. Another application of this material is its use to make electrical devices due to the dielectric properties of this type of granule.
Types of polystyrene granules
High Impact Polystyrene Granules:
Another type of granule made of polystyrene is High Impact polystyrene granule. This model of granules is known as HIMPEC and is used with the abbreviation HIPS in the form of granules by the standards of international standards in various industries for the production of various materials.
These types of polystyrenes have a higher resistance compared to GPPS, which is why they are used in the manufacture of special products. High Impact granules are commonly used to produce cooling insulation and to produce high-volume disposable containers.
Expanded polystyrene granules:
Another example of granules made of polystyrene is its expanded type, which is produced using advanced and modern devices.
This type of granule is made of a type of polymer that is supplied in white color, which is combined with a volumizing foam when made. This product, which is used in various industries, is known as Ionolite.
The most important application of this type of granule made of expanded polystyrene is its use in the production of plastofoams for roofs. In recent years, blocks made of this granule (plastofoam) have been considered as a suitable alternative to traditional materials.
Due to the popularity of ionolite, this granule has more production than other samples. Ionolite is used for construction foams and refrigerators, except for construction.
