What is EPS?What is EPS (Expanded Polystyrene Rigid Foam) ? EPS (Expanded Polystyrene Rigid Foam) is typically white colored thermoplastic material with closed pore in foam state obtained from petroleum with polymerization of styrene monomer. EPS is a material used in heat and sound insulation. Polystyrene is exposed to preliminary heading after polystyrene is supplied as raw material in small particles. Heading gas used for obtaining foam and heading particles is Pentane within EPS products acquired with heading and inter-cohesion of polystyrene particles. Being an organic component, Pentane displaces with air in very short time during and following production after ensuring creation of small pores in very little number within polystyrene particles; required condensation of material is ensured in this phase. (Afterwards, expanded particles rested in special silos are ensured to combine with one another with the help of water vapor within molds and to gain properties of material. A continuous mass that polygons combined with one another without any clearance in between is formed in honey comb appearance as a result of combination of particles with one another. Following production steps vary according to availability of packaging material or intended for heat insulation and use site of material.) Released Pentane gas is converted into CO2 available in atmosphere and H20 water vapor. With the release of Pentane, still air within little closed porous cells in great number available within the body of material (3-6 billions in 1m3 EPS depending on condensation) is locked up. When these particles magnified with pentane gas with high mechanical pentane gas displaces with air, they elude outwardly and form EPS blocks in molds. 98 % of material is still air and 2 % of material is polystyrene. Density refers composition of raw material with how many kg of 1 meter cube EPS material.
As known, still air is the most economical and environment-friendly and perfect heat insulation material. High heat insulating properties of EPS is because of still air which it incorporates within the body of particles in large number. One of the few materials ensuring the best heat insulation available throughout the world, EPS is the only material providing the same performance more economically than the other insulating materials used. As density of EPS increases, the rate of heat insulation increases. It complies with the norms of TS 7316 EN 13163 and TS 825
Tags: SPECIFICATIONS AND ADVANTAGES OF FLEXYPAN DECORATIVE INSULATING PLATES AND TRIMMING ELEMENTS • They are very light; they have easy transportation and application; they do not affect adversely static weight of building.
• They are the most economical decorative siding elements.
• They allow opportunity of design and they ensure structure to be in decorative and aesthetic appearance.
• Blocks with high density 26 kg/m3 EPS are used in Flexypan products; they provide high heat insulation. Their thermal conductivity is very low. (=0,031-0,035 W/Mk). System maintains making saving during its life time. Property of insulation does not change in time. It provides 60 % fuel saving. Heat bridges do not occur since plates cover entire structure with sole material without any clearance. Flawless thermal conduction is enabled.
• EPS is B1 class material in line with DIN 4102 in Flexypan brand products. It does not propagate flame.
• Flexypan used on the surface of product is plaster acrylic base and it is extremely durable and elastic due to used silica.
• Flexypan products do not get affected from water and humidity. They do not get wet practically since they have closed pores.
• Flexypan products are very durable when they are pressed.
• Flexypan products have a lifetime equal to building life time.
• Thickness of EPS used in production of Flexypan products does not get thinner; it remains fixed.
• Cracking does not occur in time on joint places of plates since locked system has been created on both side of Flexypan decorative insulating plates and heat bridges do not occur in time. Since Flexypan products are mounted into structure as embedded, all plates are working equally and no static and structural physics defects arising from application system occur systematically. On the other hand, since Flexypan decorative insulating plates are not anchored with lathes on the surface as different from other materials, working of such lathes as a result of expansion, condensation on back and sides of lathes (because insulating coefficient of lath is 9 folds more than insulation plate mounted to itself) and resistance losses as a result of beginning on insulating plates of lathes with nail or similar joint bars structural physics and static errors because of non-co-activation are not comprised on Flexypan plates.
• They are not hazardous to human health and environment.
• They do not require trashing and do not cause extra cost.
• Rotation of big angles is ensured at ease due to its flexible property.
• It can be painted to any color.
• Flexypan products are resistant to extraneous effects such as solar rays, cold-hot, rain, snow.
• Required quantities are delivered in the shortest time due to its production speed provided by high production technology.
• Their standard dimensions are 2000 mm. All kinds of different models can be produced on project-base apart from existing models.
• Application details can be easily solved due to its special Flexypan repair mortar provided with the products.
• Plates produced in the factory are not comprised of aggregation of 3-4 different products just in other products. Since they are comprised of one sole product, only mounting and painting works are in question. There is no need for plastering and net.
• It does not host insect and animal.
EPS Technical SpecificationsRESISTANCE TO HEAT
EPS plates provide high heat insulation. (Xhesap=0,033-0,044W/mK). Flash point of EPS is 360-370 C. Its self-flammable ambient temperature needs to reach 490 C. Amount of gas released as a result of burning of EPS is less than many materials used every building such as wood. Its resistance to heat depends on degree and duration of temperature. Though resistance of EPS material is durable to 100 C in short term period, it may be used maximum 75-85 C & minimum – 185 C depending on density of material on long-term period.
RESISTANCE TO HEATEPS plates provide high heat insulation. (Xhesap=0,033-0,044W/mK). Flash point of EPS is 360-370 C. Its self-flammable ambient temperature needs to reach 490 C. Amount of gas released as a result of burning of EPS is less than many materials used every building such as wood. Its resistance to heat depends on degree and duration of temperature. Though resistance of EPS material is durable to 100 C in short term period, it may be used maximum 75-85 C & minimum – 185 C depending on density of material on long-term period.
EPS AND BURNING STATE: EPS has two main types: a) Normal flammables (B2) b) Barely flammables (B1) It is made use of German DIN 4102 norm in classifications conducted in relation with burning state of structural materials. Flame is required to contact directly material in specific period in order for these materials of B1 class to catch fire. When flame is kept away, material is extinguished by itself. EPS material in high quality with B1 class 26 kf/m2 density is used in Flexypan brand products. HEAT CONDUCTIVITY:
Calculation value of EPS plates heat conductivity varies between 0.033-0.040 W/mK. As density increases, heat conductivity decreases. Heat conductivity of EPS is provided as 0,034 kcal/mhc in compliance with the standards stipulated by Turkish Standards Institution. Since heading gas used in production of EPS heat insulation plates displaces very rapidly with air, heat conductivities of EPS heat conductivity plates reach its ultimate value following production and do not deteriorate in time; any change which shall affect thermal resistance in their density is not witnessed when they are used in densities which application thereon requires. That heat conductivities and thermal resistances of EPS heat insulating plates remain stable during their use period is the most important advantage.
RATE OF WATER ABSORPTION:
Effective size of materials over rate of water absorption is the fact that pores are open or closed. Rates of water absorption of closed pored materials in contact with directly water are very low and EPS is closed pored material. Because Styrene composing EPS is water insoluble structure, walls of closed pores do not conduct water. Even if it contacts with direct water since its water absorption rate is very low, its properties do not change. In addition to this, if we consider that EPS shall not entirely remain within water in long term period in any building, it might be stated that it is watertight.
LIFETIME:
EPS is a material of endless use period. If EPS is applied in line with structural physics and construction guidelines in right plate and right quality and accurate thickness and density, depletion of material is no way possible.
MECHANICAL PROPERTIES AND PRESSURE STRENGTH:
It has pressure strength. As density increases, pressure increases, too. It is not fragile. One of the crucial properties of EPS is its mechanical durability demonstrated against short and long-term loadings. Mechanical properties of EPS heat insulating plates are in sufficiency which shall reveal resistance with accomplishment against mechanical effects which a building may face under normal conditions. In addition to this, as density increases, sliding, bending and tensile strengths of EPS plates increase, too. Elasticity modulus (E) of EPS is between 0,6-3,1 MPa. EPS heat insulating plates may be classified in line with SIO values and bending resistances in international platform. Tensile strength vertical to surface of EPS heat insulating products varies between 20 kPa and 400 kPa.
