Various EPS Uses

1. EPS Packaging
EPS is a widely used packaging medium for fresh fruit,vegetables and seafood to protect these products during storage and transportation between grower and market.EPS packaging reduces the cost to consumers by reducing the waste associated with spoilage that can occur in transportation to markets.
It is also used to protect fragile and expensive manufactured goods during storage and tran sportation between factory and consumer.
EPS is chosen for these applications because of its attractive balance of properties,including thermal insulation,shock absorption,moisture resistance,light weight and suitability for food contact.EPS has been shown to extend the freshness of fruit when compared with alternative packaging materials such as cardboard.

2. Sandwich Constructions: Light Outer Walls
The need for rationalized building methods and employment of materials has encouraged the use of light prefabricated components. Lightweight walls are now largely assembled from such components, which are commonly sandwich constructions and may have provision for ventilated sidings.
In order to control the environment within buildings, high thermal inertia is often essential. In cool climates with heated buildings this is always the case; in warm climates much depends on the relative importance of daytime and nighttime use, the diurnal temperature range, whether or not the building is air- conditioned, and to what extent the building is exposed to direct sunlight. In general, all air- conditioned buildings need high thermal inertia.
Thermal bridging often requires considerable attention in lightweight walls; particular care should be taken with the insulation of joints and metal frames.

3. EPS External Wall Insulation
EPS external wall insulation is an accepted way of adding thermal value to the outer face of most external walls of buildings.
Its versatility enables it to be used with a variety of finishes including plastic weather-boarding, cladding, tile hanging and reinforced- render systems.
EPS external wall insulation when used on the external face of masonry wall maximizes the natural thermal capacity of the wall and assists in the reduction of thermal fluctuations.
Given that heating and air- conditioning interior rooms consume vast amounts energy and accounts for approximately 80% of total energy consumption with 30% being lost through un- insulated walls, external wall insulation offers a highly cost effective way of reducing this loss.

4. Insulated roof
From the viewpoint of construction physics,the roof is the most highly stressed part of a building.Heat and cold,dryness and wetness,storms and snow act 0n it from the outside,internal relative humidity acts on it from the inside.Roof designs and construction materials have to be made with this in mind.EPS play a significant part in this connection,as insulating layers,sealing sheets or vapor barriers. Whether a flat roof or a pitched roof,whether,someone’s home or a factory building:EPS are always involved because they have outstanding insulation and offer economical answers as insulating systems.

5. Cold Storage
EPS is an excellent insulation to enclose close storage space used to cool and store food, flowers and other commodities at temperatures ranging from normal room temperature (68°C) down to cryogenic temperatures ( - 148°C ). EPS is well suited for this type of insulation because of its excellent thermal resistance, its low permeability to water vapor and air, low absorption of water, dimensional stability, chemical inertness and durability, lack of odor and vermin resistance.
EPS is also used to insulate containers that hold cold liquids or gases pipes and vessels in cold environments such as utility and sewer lines.

6. Buoyancy Systems
EPS can be used for a variety of flotation devices, such as rafts, docks and billets. Buoyancy billets are usually produced in standard sizes but can be easily customized. They are suitable for fresh and salt water and are unaffected by winter temperatures. EPS billets can support 55 lbs. per cubic foot, which is significantly more than typical wood flotation devices. Since EPS is lightweight and easy to work with, installation and maintenance costs are low.
EPS buoyancy systems are safe for the environment. They are ozone friendly, no CFCs are used in their production, and they have no food value for marine animals. Growth of marine life in stagnant water does not impair the buoyancy of the billet and can be easily removed with a scraper.
EPS flotation structures exhibit excellent rebound characteristics with minimum rocking, provide less resistance to breaking waves and are quieter than those with other types of flotation such as drum floats.

7. EPS and the Environment
Strength, insulation properties, light weight and superior cushioning are all characteristics most people associate with EPS. What's equally impressive are the ways EPS and the companies that use it are contributing to environmental quality.

8. Recycling EPS Packaging Materials
The UK EPS industry has worked for many years to actively encourage the recycling of used packaging material and many large electronics companies and retailers are successfully collecting and recycling their EPS.
