What is XPS Foam Board?

Extruded Polystyrene, referred to as XPS, is a closed cell insulation product commonly used in remodeling and new construction applications. Extruded polystyrene XPS foam begin as a solid granule of polystyrene resin. Our need the plastic granules into an extruder where they are melted and mixed with critical additives to form a viscous fluid. and we need to inkjet foaming agent to ensure the expansion of the plastic. Under precisely controlled temperature and pressure, the plastic mixture is forced through a die into the desired shape. Last, we can cut the hard foam into a customized dimension.

The Features of XPS Foam Board 

Extruded polystyrene insulation board is an improved material of general purpose polystyrene(GGPS) using the process of extrusion. This continuous process results in a closed cell structure with smooth skin on the upper apex and bottom of the board. Every cell wall of the XPS spume board is interlinked and consistent which prevents water penetration to the structure of the extruded polystyrene insulation board and provides long-term strength and durability. The advantage of XPS foam boards are stably and light, so we can transport and cut this product easily. Now, XPS insulation foam board is the best heat-resistant material in the world.

Applications of XPS Foam Board

XPS extruded foam board has good 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
