The abbreviation for EPS is derived del ingles Expanded PolyStyrene. Polystyrene is naturally transparent, but can be coloured with colorants. This is often used blended with General Purpose polystyrene or on its own in a wide range of household applications and in food packaging. Required fields are marked *. How is it manufactured? With respect to the upper end the use temperature limit is around 100 ° C for short-lived actions, and about 80 ° C for continuous actions and with the material subject to a load of 20 kPa. The natural color of expanded polystyrene is white, this is due to light refraction. Extrusion – the material is fed into the extruder, where it is melted. For several years, expanded polystyrene (EPS) has been utilized as a material of choice in several food packaging applications, cost-effective and energy-efficient insulation in construction applications as well as cushion transport packaging material for shock sensitive goods and many more. EPS products, like all materials, are subject to dimensional variations due to thermal influence. ASTM 578-95 “Physical property requirements of polystyrene foam thermal insulation”, American Society for Testing and Materials. Color can be added, and the extruded material is then molded into a new value added product. The temperature range in which this material can be used safely without its properties being affected has no limitation at the lower end (except dimensional variations by contraction).

Polystyrene has a number of properties: it has a low melting point, it is translucent before tint is added, and it is hard and brittle. After 45 years in front of scribes and technicians from different European institutes, some of this material was raised and subjected to all possible tests and verifications. Extruded Polystyrene is manufacture in one density. Xytron™ (PPS)’s Withstand Durability Challenges & Extend Service Life, Expanded Polystyrene (EPS): Ultimate Guide on Foam Insulation Material. VIDEOTUTORIALS – The use of expanded polystyrene (EPS) in Civil Engineering works, VIDEOTUTORIALS – Use of Expanded Polystyrene (EPS) in Interior and Exterior Decoration, walls, molds, borders, cornices and more, Expanded polystyrene (EPS) packaging, uses of Expanded Polystyrene in the packaging of various industries, VIDEOTUTORIALS – Manualities with expanded polystyrene (EPS), Uses and Applications of Expanded Polystyrene (EPS) in Packing and Packaging, The use of expanded polystyrene (EPS) in Systems of Drainage of Water of a Land, The use of expanded polystyrene (EPS) in Hydraulic Projects, Properties and Characteristics of Expanded Polystyrene (EPS). However its major application is as a protective packaging for consumer electronic products and white goods. The products and articles finished in expanded polystyrene are characterized by being extraordinarily light but resistant. High Impact Polystyrene: Polystyrene containing a polybutadiene rubber impact modifier is opaque or translucent rather than transparent. EPS manufacturing does not involve the use of ozone-layer-depleting CFCs and HCFCs, No residual solid waste is generated during its manufacturing, It aids energy savings as it is an effecting thermal insulation material which helps reduced CO, EPS is inert and non-toxic. Expanded polystyrene (EPS) is a kind of stable foam with low density, consisting of discrete air voids in a polymer matrix. TextosCientificos.com, Your email address will not be published. EPS is commonly preferred thermoplastic material for over half a century due to its performance, technical versatility, and cost-effectiveness. The material has been modified by the addition of flame retardant additives. Expanded Polystyrene (EPS) is technically defined as: “Cellular and rigid plastic Material made from the moulding of expandable polystyrene preexpandid pearls or one of their copolymers, which has a closed, air-filled cell structure”. Alternative Building Material (expanded Polystyrene) - Properties (4) - Nairaland. Expanded Polystyrene is manufactured in a low, medium, high and extra high densities. Explore more about this polymer and find out its benefits, properties, recyclability etc. Depending on the application, densities range from 10kg/m3 to 35kg/m3. EPS: Expandable polystyrene The expanded or foamed polystyrene is thermally insulating, has high impact resistance and good processability. Approximately 98% of the material volume is air and only 2% is solid matter (polystyrene), the air at rest being an excellent thermal insulator. Hatton, Kayo: Jorge Marcondes, Lucy McProud, EPS is sup-plied to molders in the form of a polystyrene bead; EPS beads are loaded with a blowing Polystyrene is mixed with additives and a blowing agent – which is then melted together through a dye, XPS’s blowing agent stays embedded in the material for years, XPS is often selected over EPS for wetter environments that require a higher water vapour diffusion resistance value, The compressive strength of XPS is greater than that of EPS.
