XPS Foam Board is an superior insulation Material,excellent Vapor Barrier Property,and extremely low water absorption under high humidity environments.Extruded Polystyrene Foam starts as Soild 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.It is Widely used in Wall insulation,low-temperature storage facilities,parking platform,the airport runway,construction of Concrete roof and the structure of the rood,highways.
