Expanded Polystyrene
Expanded Polystyrene (EPS) is a rigid and tough , closed-cell foam it is usally white made of pre-expanded
Polystyrenebeads. Famillier uses include molded sheets for building insulation thermal resistivity is usally about
285 m K/W(or R-4 per inch ) some EPS bords have a flame spread of less than 25 and a smoke developed index of less
than 450m which means they can be used without a fire barrier(but require a 15-minute thermal berrier.) the density range is about
8-24kg/m
EPS also avilable in pipe section form the thikness of pipe section that are avilable are (25,40,65,75,100,125,150,200)
the internal dimeter of EPS pipe section are avilable in (15,20,25,32,40,50,65,80,100,125
,150,200,250,300 & 350)
