The new thermal insulation material PAOPOR(not old bubble) adopts particle fire insulation fm teachnology, uses coplymerization modtication to makeEPS monomer particles have the same characteristics as fire retardant substances,and uses microghase composte technology to frm a fire insulationfimn on the surtace of eachorganic particle,so that each particle forms a relatively independent organic particle fire prevention unit.  in case on flame itforms a continuous honeycomb structure to block the transmission and penetration of flame and prevent the occurence of comtbustion. PROPOR(not oldbubble)B class fire insulation board can be combined with the actual construction situation according to the design characteristics and functionalrequlrements of the projacl. has strong operability.Not oid bubble is also known as"real gold board". which belongs to a new type of benign foamboard,core material fire retardant dlass B.With thermalinsulation. Its own weight is light, easy to install.
