Eps raw material for polystyrene 

1.What is EPS?

E.P.S. (Expandable Poly Styrene) is a lightweight, rigid, plastic foam insulation material produced from solid particles of polystyrene. Expansion is achieved by virtue of small amounts of pentane gas dissolved into the polystyrene base material during production. The gas expands under the action of heat, applied as steam, to form perfectly closed cells of EPS. These cells occupy approximately 40 times the volume of the original polystyrene bead. The EPS beads are then molded into appropriate forms suited to their application. Products made from foamed polystyrene are nearly ubiquitous, for example packing materials, insulation, and foam drink cups 

2.Characteristics 

Good flame-retardant, good frothing good preserving, good binding and low heat-conducting rate.Oxygen index over 30(testing after 7-14 days flowing)

  

Sandwich Panel  is a kind of light weight energy saving wall material taking calcium silicon board (fiber cement board) as face panel, cement, EPS, fly ash as core and forming by one time compound.  It can widely be applied to wall materials of various high and low buildings such as: bank, office building, hospital, school, hotel, shopping mall, amusement hall, old house reconstruction, residence and workshop.

               

3.Application   

1>.Packaging: i.e.: Vegetable and fruit box, Fish box, Electronics packaging;

2>.New Building Material: i.e.: Sandwich panel, 3D panel, Brick insert, Insulated Concrete Foam (ICF)

2>.Plastic Foam Flotation: i.e.: Float

3>.Decorating Material: i.e.: Cornices, Ceiling tiles, Articles in arts and crafts for advertisement and decoration;

4>.Full Mould Casting: i.e.:

5>.Protecting material: i.e.: Anti-freeze pad to cushion foundations of roads and railways in high cold region;

6>.Filter material: i.e.: Applicable in medium and small scaled water supply system;

7>.Other applications: i.e.: Applicable in seeding nurseries for hydroponics; Mixed with clay and cement to manufacture lightweight wall tiles and cement castings; As filling material for pillow……

4.Advantages

1)Being light in weight handling & installation become very easy.No brick and plasterign are required

2)5% Additional floor are will be available on replacing 125mm birck wall with 60mm,75mm panels

3)Specially designed tongue and groove(patent) arrangement ensures a perfect joint and makes constrution faster

4)More suitable for seismic & cyclone prone zones

5)Excellent adhesion between core & facing sheets

6)Good Sound & thermal insulation properties

7)Humidity,water and termite resistant properties to withstand any adverse weather conditions

8)Panels have a fire rating of 4h

5.Storage

The EPS series products of our company need to be put on the place where it is cool and

ventilated, keep the storage temperature below 20°C in order to minimize the lost of

frothing agents from escaping. The lower the temperature is, the better the quality is. The

products should avoid rain, fog, snow and lighting up from the sun, static electricity and

flame. Once the package material of the products is open, it should be used up as quickly

as possible. Otherwise, the remaining EPS might lose its function due to escaping of

foaming agents. If the EPS is stored too long, the expandable times might decrease
