Disadvantages
Polystyrene also has some disadvantages. Low temperature resistance imposes limitations in certain applications. It is not suitable for use in cold environments. The fact that it does not retain oxygen and water well is a disadvantage in some cases. Therefore, it should be used with caution in humid or oxygenated environments.
Its fragile structure may make it susceptible to physical damage. This causes polystyrene to be weak in some applications. Care should be taken especially in places exposed to impacts.
Areas of Use
Construction Industry
Polystyrene in the construction industry insulation material It is widely used. This material provides ease of transportation and installation thanks to its lightness. It saves time and labor in construction projects. It offers an effective solution in sound and heat insulation. These features increase energy efficiency. Polystyrene also attracts attention with its moisture and water-repellent properties. Thus, it increases the durability of structures.
There are two main types of polystyrene used in construction: expanded polystyrene (EPS) and extruded polystyrene (XPS). EPS is often used in walls and roofs. XPS, on the other hand, is preferred in areas that require more durability. Both types improve insulation performance.
Packaging Industry
Polystyrene for packaging materials is an ideal choice. Its products stand out with their protection and lightness features. It is frequently used especially in food packaging. It preserves the freshness of food products and protects them from external factors. Also, it is easy to transport. This reduces costs.
