Extruded Polystyrene Foam starts as solid pellets of polystyrene resin. We first feed the plastic pellets into an extruder where they are melted and mixed with critical additives to form a viscous liquid. Then we inject a blowing agent to expand the plastic product. Under well-controlled heat and pressure, the plastic mixture is forced through a mould to form the desired shape. Finally, the rigid foam is trimmed to a custom size and this is the final XPS foam board.

Key features

(1) Superior thermal Insulation
XPS insulation board has dense surface layer and closed-cell structure inner layer. Its thermal conductivity is much lower than EPS, so it has better thermal insulation performance than EPS. For the same exterior walls, its thickness can be less than other types of insulation materials.

XPS insulation board has an excellent R-value, which is a measure of the insulation's ability to resist heat flow. The higher the R-value, the more effective the insulation is at preventing heat transfer. XPS insulation board typically has an R-value of 4.5 to 5 per inch, which is higher than many other types of insulation materials. This high R-value makes XPS insulation board an ideal choice for homes and buildings in areas with extreme temperature fluctuations.

(2) Excellent resistance to moisture
Even in a highly humid environment, Extruded polystyrene board can still maintain good thermal insulation performance; suitable for cold storage and other buildings with special requirements for insulation, can also be used as an exterior wall finish material for the building of brick or stone.

(3) Easy to use and install
No special treatment is needed for the construction of XPS foam board.

(4) High compression strength (between 150-1000kpa)
XPS insulation board has a high compressive strength(Between 150~1000 kpa), meaning it can withstand weight and pressure without deforming or breaking. This makes it an ideal choice for applications such as foundations, where the insulation will be subject to the weight of the building. XPS insulation board can also be used in roofing applications, where it can support the weight of foot traffic and other loads.

(5) High density and low water absorption rate      
XPS insulation board is also known for its moisture resistance. The closed-cell structure of the foam makes it difficult for water to penetrate the insulation, making it an ideal choice for areas prone to moisture and water damage, such as basements and crawl spaces. XPS insulation board also does not support mold growth, making it an excellent choice for those with allergies or respiratory issues.

(6) A wide range of applications
It can be used in exterior walls, floors, roofs, cold storage, high-speed rail, etc.

Application

XPS extruded insulation board has superior insulation performance, excellent vapor barrier property, and extremely low water absorption under high humidity environments

(1) Civil Engineering 
XPS extruded foam board can settle the problem of water channels frost cracking in canal engineering in cold regions. In the South to North Water Diversion Project XPS boards were used as the anti-frost material of the channel. The bonding strength is high between Feininger XPS foam boards and concrete layers. The engineering practise applications show that the XPS board can meet the requirements of mechanized concrete construction.

(2) Cold Storage Purification Engineering 
XPS foam boards can prevent moisture condensation effectively. Therefore, this material is widely used in cold storage rooms with superior resistance to water vapor penetration and high compression performance.

(3) Building Insulation and Decoration Field
Usually, about 15%-20% of the heat loss is through the floor/roof in buildings, so it's very important to offer dwellers a comfortable environment by effective insulation treatment to avoid condensation on the floor/roof. XPS foam board as building insulation has incomparable advantages. It can be used in the following fields.
* Roof insulation system
* Wall insulation system
* Floor insulation system
* Basement insulation system
* All kinds of composite sandwich panels
* Decorative molding 
* Decorate condole top
