EPS IN HEAT INSULATION
Standard is the standard defined as “TS 7316 EN 13163 Thermal Insulation Products – For buildings – fabricated expanded polystyrene foam – properties”. The important feature of the content of this standard is that today it prevents the use of products with densities less than 15 kg / m3 for thermal insulation in buildings.
The first three stages of the production of EPS thermal insulation boards (pre-blowing, maturation, and molding) are similar to the production in other applications. However, in heat insulation plates, large blocks are produced during the molding stage and the plates are made of hot wire, etc. It is preferred to be obtained by cutting methods.
Thus, the ability of the surfaces to adhere to mortar is increased. It is only necessary to apply the EPS boards after a certain period of time (3-5 weeks according to the manufacturer’s recommendations) for external insulation applications with thin plaster called jacketing. There is no need to wait for any of the other application techniques.
Almost all kinds of materials can be coated on the surfaces of EPS plates and composite elements suitable for application conditions can be produced. EPS products are used for heat and sound insulation in buildings, as well as in some special engineering structures and some non-construction sectors for various purposes and their usage areas are constantly developing.
The main reasons of choice for EPS; In addition to having superior technical features, its properties can be changed in the desired direction depending on the density, its cost is low thanks to the ideal production technology, its ability to maintain its performance throughout its life cycle and it is an environmentally friendly material. EPS Products provide the desired performance without causing material waste and therefore with the most economical solution: EPS insulation boards; Provides high thermal insulation. As its density increases, its thermal conductivity decreases.
The thermal conductivity of EPS is low and stable, it does not change depending on the inflating gas and time. It is resistant to pressure. As the density increases, the compressive strength increases. It is not fragile. It has a high bending strength as a thermal insulation material. Since it has closed pores, it practically does not get wet and makes the insulation continuously. It has no capillary water permeability and is not hygroscopic. Vapor impermeability can be adjusted at desired values. As the density increases, the vapor impermeability increases. Its thickness does not get thinner over time, it remains constant. It is very light, easy to carry and apply. It is an economical insulation material and offers the same thermal performance at a lower cost. It is an environmentally friendly material. It does not contain ozone depleting CFCs (Chlorofluorocarbons) and derivatives (HCFCs). It does not cause climate changes.
It is a recyclable material and does not create waste that will pollute the environment after production. It is eternal life. As long as the building stands still, it continues its insulation task with its first day performance. EPS offers application options that can be produced in a wide range of density. It prevents resource waste by choosing the most suitable product for the job.
Thermal insulation in buildings saves energy, reduces gas, soot and dust emissions and prevents environmental pollution. Wall, thermal bridges, floor and ceiling surface temperatures have important effects on the building envelope as well as the interior comfort. Adequate insulation contributes to the quality of life and helps to preserve the building fabric. A healthy and comfortable life is only possible in places with suitable temperature and humidity conditions. If a benefit-cost comparison is made, thermal insulation is an investment that is both ecologically and economically beneficial and quickly recovered.
With the insulation made with the right material, detail and workmanship, it is possible to obtain comfortable spaces and save at least half of the heating and / or cooling bills every year. Thermal insulation is useful in reducing energy consumption for heating as well as energy consumption for cooling. First of all, it is thought that the reason for mold and paint damage, and even the perspiration seen on the interior surfaces, is caused by the ingress of water from the outside in many cases, but in fact, the temperature of the inner surfaces decreases as a result of the lack of thermal insulation and the condensation of the indoor steam on these surfaces. It will be possible to solve these problems with thermal insulation.
In addition, in terms of the bearing capacity of the building, the most appropriate protection to prevent corrosion of concrete and iron is to apply continuous heat insulation to the building from the outside. Thus, since concrete and iron are protected from the negative effects of atmospheric conditions (rainfall, temperature, etc.), the service life of the building will be extended safely. The formation of thermal bridges will also be prevented.
The fact that heating / cooling devices can be selected with a lower capacity as a result of thermal insulation and their equipment requires less cost are also financial gains in addition to the fuel savings to be achieved every year.
EPS IN PACKAGING
The usage area of EPS as a packaging material is very wide, it is produced in 20/100 kg / m3 densities, with the desired size and shape by injection machine. These special molds made of aluminum are designed separately for each product. EPS removed from the mold becomes a ready-to-use packaging material. It is a vital issue that any product is delivered to the consumer without any damage after the production stage. No matter how high the quality is during the production phase, all efforts will be wasted if the product cannot preserve its initial properties when it reaches the consumer.
EPS packaging protects the product from all kinds of dangers during transportation. EPS is a material with high technical properties, it is not affected by moisture, water, UV rays or compression, does not deteriorate, does not lose its mechanical and technical performance properties over time, it is an environmentally friendly material since it requires low density energy during production and is recyclable.
EPS has no harm to health either during its production or use. It is suitable for food directing. Some products need to be kept in their temperature so that their properties do not deteriorate until they reach the customer. EPS provides a very good insulation. It does not negatively affect the smell and taste of the product inside. Since it is not a nutrient for micro organisms, it does not contain bacteria, EPS is waterproof due to its closed porous structure.
For this reason, airlines prefer to transport fish in EPS boxes. In addition to their superior properties, EPS products are environmentally friendly.
Some usage areas in packaging are as follows;
White goods and electronics (Refrigerator, television, etc.)
Glassware and decorative items (Food, glass sets, souvenirs, etc.)
Food (Fruit and vegetable crates, fish box, ice cream box etc.)
In the pharmaceutical industry (Vaccine, cold chain, etc.)
As a support and packaging material in the furniture industry
Plumbing Products (Faucet, armature, shower hose, toilet seat, etc.)
Fish and Seafood (Fish box, mussel, oyster, squid, shrimp boxes etc.)
Meat and Meat Products (Meat, chicken, sausage, etc.)
Dairy Products (Milk, yoghurt, cheese containers)
Tourism Sector (Thermos, Colt-box, ice box etc.)
Floristry Sector (Flower pots, containers, seedling growing containers)
Marine (Life jackets, pontoons etc.)
