What is Expanded Polystyrene or EPS Polystyrene Foam?
wuxing supply professional and honest service.
Expanded polystyrene (EPS), is produced from small beads of polystyrene that are fed into a mold. Heat or steam is then applied to the mould which expands the polystyrene beads and fuses them together. The expansion process causes the expanded foam to fuse together in irregular patterns that leave tiny spaces or irregular gaps in-between the foam cells.
Insulating Properties of EPS Foam
Inconsistent gaps between the EPS foam cells allows air & moisture to permeate throughout the foam, making EPS a less than ideal solution for moist environments.
Strength and Rigidity of EPS Foam
EPS foam cellular structures contain voids or spacing in-between the cells; these gaps form an irregular structure throughout the foam, making it less dense and rigid than extruded foams.
What is Extruded Polystyrene or XPS Polystyrene Foam?
Extruded Polystyrene (XPS), is manufactured via an extrusion process where plastic resin and other additives are combined and extruded through a die. The extruded foam then cools and expands into it&#;s final shape.
Insulating Properties of XPS Foam
XPS foam is considered to have a closed-cell structure wherein the cells are packed together tightly and have no voids or spacing between them. The tightly packed cells of XPS foam help prevent air & water ingress and make it more ideal for moist environments.
Strength and Rigidity of XPS Foam
XPS foam has a tightly packed closed-cell structure that makes it extremely rigid and strong, making it ideal for structural panels.
UltraBoard sheets are manufactured with an XPS foam core because of its rigidity and durability; as well as its resistance to moisture. When combining an XPS foam core with a plastic facer like our UltraBoard Classic product, you get an all-plastic board that is ideal for many interior environments and has a durability rating of 10 years.

XPS is a thermal insulation board of extruded polystyrene, having a Planed and Grooved surface applicable for Cold Chain Logistic Truck Body Manufacturing.
Extruded polystyrene board can be used as foundation pavement, airport road expressway, etc. XPS polystyrene foam effectively alleviate the ground collapse caused by road leakage because of waterproof and lightweight.
XPS Foam prevents penetration of moisture, decrease damage of extreme weather on road base, minimize frost and prolong its life, so as to ensure traffic safety. Usually 500kpa, 700kpa XPS Insulation Board are applied in this special area.

High Compression XPS BoardHigh Compression X700 Extruded Polystyrene Foam Board is a thermal insulation board of extruded polystyrene, bearing a Compression Strength of 700Kpa, having a smooth surface to prevent the formation of thermal bridges. Due to its Extra High Compression Strength and good Thermal Resistance, it is widely applied in China High Speed Railway Base . The XPS layer in such use prevent railway from damages caused by freeze thaw.
Plastic Packing XPS Foam BoardThe Blowing Agent of CO2 is added in the formulation in order to reach a Compression Strength of 700Kpa. The CO2 tends to make smaller pore size and make density as high as 50Kg/m3, which enables XPS to bear higher Compression Strength. The existence of CO2 presents higher System Pressure requirement to the extruder. Due to boiling point of CO2 is as low as &#; 78.4 degree, the Extruding System Pressure must be kept around 25Mpa to maintain its liquid state, which means Mould can not be opened largely. This also determines that thickness greater than 50mm at 700Kpa is difficult to produce.

60mm XPS BoardXPS Foam board has to meet fire classification requirement of at least B2 Grade in China. According to China National Standard GB/T .2, B2 Grade corresponds to an Oxygen Index of > 26 while B1 Grade corresponds to and Oxygen Index of >30. Customer is sometimes more interested in how those China Fire Classification Grade matches European Standard. Well, general speaking, B1 Grade in China National Standard equals to Grade B & C in EN while B2 Grade in China equals to Grace D & E in Europe.
Plastic Packing XPS Board with OURGREEN LogoWhen XPS is installed for building insulation, as being used together with Roof / Wall / Floor, a thickness of less than 50mm is enough. In area such as Cold Chain Logistic Truck manufacturing, Cold Storage, Insulation board at thickness of 75mm / 100mm or more is preferred. Especially in Cold Storage, where release of cold is critical. People tend to require large panel like XX100mm or even XX150mm. In this case XPS Extrusion Line with small capacity is far from enough. Bigger Extruder with higher capacity of 800- Kg/h is expected.
XPS Insulation in XPS Production LineStyrofoam Insulation Board, at its early stage, is produced with Blowing Agents of HCFC, a kind of Freon. Freon technology is easily accessible for many manufacturers. However, as Freon damages Ozone Layer, it is generally recognized that Freon must be phased out world wide, which is plan of UNIDO.
More and more XPS manufacturers apply CO2 as well as other non-freon gases in XPS production, making final XPS Foam Board totally eco-friendly. We are contributing to environment protection by replacing Freon. Together we build our green world!

For example, most customer demands 35mm-85mm thickness, if the thickness required is the same as above, the price will lower than other different thickness.
As you know, density is closely related to the producing cost of Styrofoam Board. The higher density you need, of course the price is higher too.
Normally we have three kinds of surface, Smooth or withskin surface, grooved surface and rough surface. Smooth or withskin surface is the cheapest.
Planned and Grooved Extruded Polystyrene InsulationThe compression strength is relates to density. The higher compression strength you need, the density of XPS Foam Board will higher, of course the price is higher than usual compression strength Styrofoam Board.
Thermal conductivity is a property of styrofoam board to conduct heat throughout. The lower thermal conductivity, the warmer the material. Thermal conductivity of XPS foam is 0.029&#;0.032 (25±5) ˚&#;, W/(m*K).
There are 3 types fire ratings XPS board. B1 Oxygen Index of >30, B2 Oxygen Index of >26 and non flame retardant boards.
The maximum shrinkage of XPS insulation board is lower 2%.
XPS boards are available in yellow, pink, blue, white and green. Among these color, white is regular color.
XPS board&#;s length has nothing to do with price. If you need custom dimension, maybe XPS board would charge you a litte if your quantity is small.
