The Applications of polystyrene in construction
The applications of polystyrene in construction are very diverse. We know that this material is usually white and is very suitable for insulating buildings. Insulation of floors and roofs of buildings with polystyrene is one of the most important applications of these plastics.
These materials withstand pressure and temperature; For this reason, they can be used inside and outside buildings. If you want to know the types of polystyrenes and their applications in construction, stay with us until the end of this article.
Why is polystyrene popular all over the world?
There are different types of thermoplastic materials. For example, high impact polystyrene and GPPS, which we will explain below. In addition to being insulating, these materials are durable and can maintain their stability. In addition, these materials are lightweight and are good insulators for moisture. For this reason, they are used in construction.
Polystyrene panels are thin and, in addition to absorbing moisture, can be sound insulation. These features have led to the use of these plastics in the form of blocks on the roofs of buildings. These blocks are usually compact and fireproof and come in many types. These polystyrene blocks are inexpensive and easy to transport.
The variety of these blocks is due to the type of polystyrene that has been used in their manufacturing process. In the following, we will examine different types of polystyrenes together. These polystyrenes have special properties and have different uses.
Introduction of polystyrene types
polystyrene types
Before examining the applications of polystyrene in construction, we introduce its types. As mentioned, different types of polystyrene have different properties and different uses. Types of polystyrene:
1. High impact polystyrene or HIPS
This polystyrene, which is very resistant to impact, is a type of polystyrene that is not used in construction! This means that the use of HIPS polystyrene in construction is not a reasonable choice. On the other hand, this type of polystyrene is used to make highly impact-resistant plastics.
2. General Purpose polystyrene or GPPS
This polystyrene is used for general purposes. Distinctive features of this type of polystyrene are good strength and impact resistance. Also, this type of polystyrene is transparent due to its irregular molecular structure and is used in various parts of construction.
In addition, this type of polystyrene is also used in the production of home appliances and transparent plastics. This polystyrene, known as crystal, has excellent electrical properties. After GPPS is used in building wiring.
3. Expanded polystyrene or EPS
One of the most widely used polystyrenes in construction is expanded polystyrene or EPS. This type of polystyrene is also known as ionolite. It is a white polymer and has heat-insulating properties. In addition, it is fire resistant and is used in sheds and sandwich panels.
EPS is commonly used in ionolithic roofs of buildings. These roofs are light and suitable for various uses.
4. Extruded polystyrene or XPS
Another type of polystyrene that is not used in construction is XPS. This polystyrene is a type of polystyrene that is produced during the extrusion process.
Advantages of using polystyrene in construction
Advantages of using polystyrene
Polystyrenes are used in different parts. These applications are due to the extraordinary advantages of these polymers. These benefits include:
- Proper stability
- Moisture resistance
- Resistance to pressure and impact
- Resistance to fungal growth
- Reduce concrete consumption in buildings by up to 30%
- Reduce dead loads in the building
- Reduction of pollution produced in the construction process
- Recyclability
Disadvantages of applications of polystyrene in construction
Every material used in different industries has advantages and disadvantages. These disadvantages include:
- Damage and discoloration of these materials after exposure to light
- Melting at a temperature of 120 to 125 degrees
- Flames against high temperatures
- Burning in places without oxygen
- Toxic fart release during the fire
- Reaction with industrial solvents
A summary of the study of the Applications of polystyrene in construction
These materials are a type of synthetic polymer that is formed by the bonding of styrene monomers. Styrene monomer is a chemical derived from oil. As mentioned, polystyrenes are widely used in construction.
These materials are very durable and are good heat and sound insulation. In addition, the use of these materials reduces construction costs and pollution. In addition, the use of different types of polystyrene is seen in today’s world. For example: use on the floor and ceiling of buildings, use on wallpaper, use in the manufacture of plastic appliances, use in the manufacture of home appliances and furniture, and use in the manufacture of electronic components.
