EPS is Expandable Polystyrene. A versatile plastic available in the form of sheets in varying thickness, moulded and cut pipe section for low temperature insulation of cold stores to preserve perishables, industrial plants operating at temperatures below ambient temperature, thermal insulation in building and versatile packaging material which can be moulded into any shape and design for packing electronics, glassware and other fragile products. Milky snow white EPS improves present ability of the product packed in it. EPS is also used for manufacturing ice boxes, picnic boxes and containers to keep the food hot.
EPS besides being snow white is also feather light, normal product density range 15-35 kg per cubic meter material, with rare combination of physical and chemical properties. These properties give it a unique advantage in the field of thermocol insulation.
Thermocol Insulation Of Building:
From the viewpoint of construction, the roof, no matter of what design, is the most vulnerable part of the building for absorption of solar radiation particularly in tropical countries like India. If the roof is to fulfil its protective function, EPS will play a significant role in providing thermal protection. Whether a flat roof or a pitched roof, a home or an office building, a factory, workshop or warehouse, EPS will always be an advantage because of its outstanding insulation property.
Cold Stores For Food Preservation :
Enough food for rising population is an anxiety. The solution lies not only in increasing food output but also in the simultaneous prevention of waste and spoilage of seasonal surpluses. Since most foods stay longer at low temperatures, cold stores are the logical approach to the problem. Economic operation of the refrigeration machinery and the crucial maintenance of steady storage temperature is enabled by the thermal insulation lining of the roofs, walls and floors of storage chambers.
Industrial Refrigeration And Air-Conditioning :
Most manufacturer industries involve processing, storage and transport of special products at controlled low temperature ranging from freezing to below 0 degree C like the manufacturers of chemicals, petrochemical, fertilizers, drugs, pharmaceuticals, synthetic yarn, electronic, optical and precision goods. Failure of temperature control at any stage of the technical process could affect the functioning of all interlinked operations and bring the whole production to a standstill. Therefore, any compromise on the quality of thermal insulation material that one may be tempted to make on the basis of initial cost will prove disastrous as it may lead to loss of production or quality of the product. Reliability dictates that only the best insulation material should be used in these fields.
Thermal Insulation In Transport:
Refrigerated railway wagons for fish, tankers for liquids, insulated trucks for road transportation of ice-cream, milk and other foods including refrigerated cargo holds in ships. Insulated containers like ice buckets, fish boxes, transport containers for dry ice, frozen vaccine, blood plasma medicine are examples of thermal insulation being used to preserve and protect the large variety of heat sensitivity goods during transport from place to place in adverse weather conditions.
EPS Is Best choice: Expandable Polystyrene is the superior, low temperature thermal insulation for insulation of building, cold stores and industrial insulation because of its low thermal conductivity backed up by its “Closed Cell” structure. A natural defence against moisture penetration. EPS being lighter material is easier to transport, store, handle and fix.
The properties that make expandable polystyrene an excellent packaging material are:
- Extraordinary combination of lightness, rigidity and shock absorption.
- Unique snow-white color and softness.
- Resistance to moisture and weathering.
- Being tasteless and odorless, it does not harbour fungus.
- Can be moulded to any desired shape with designs and trade name embossed.
These advantages have earned the product worldwide patronage in packaging applications. Beside packaging application product is used in lifebuoys, fishing nets, floating bridges, buoyancy blocks of expandable polystyrene fitted in boats make them virtually unsinkable.
Expansion & Contraction Joints:
Specific thermal movement for large areas and lengths where the temperature gradients are such that substantial thermal movement of various construction materials vary, EPS can be successfully used as an expansion jointing material. While designing specific joints the relative movement of construction materials used should be taken into account.
