What are the roof insulation materials?
Polyurethane is a new polymer material developed from Germany in the 1960s, known as the "fifth largest plastic" (following polyethylene, polypropylene, polyvinyl chloride, polystyrene)
Compared with EPS sheet, XPS board is made of polystyrene resin and other additives by extrusion process has a continuous uniform surface and closed-cell honeycomb structure of the plate, the closed-cell structure of the insulation material can have different The pressure (150-500Kpa) also has the same low thermal conductivity
Is made from volatile polystyrene beads containing volatile liquid foaming agent, and a white solid having a fine closed-cell structure which is thermoformed in a mold after being preheated by heating
Polystyrene foam is divided into expansive EPS and continuous extrusion type XPS two: polystyrene board full name polystyrene foam board, also known as foam board or EPS board
