There are significant changes underway in the supply of Styrofoam the market leading extruded polystyrene. During 2018 Dow Chemical will cease the manufacture of blue Styrofoam and replace with a new improved product called Xenergy Styrofoam. This product will be grey in colour and offer the same mechanical properties but will provide improved thermal performance. The process of winding down stocks of blue Styrofoam is already underway with some grades already exhausted such as RTM, these will be supplied in the new improved grade of Xenergy. Other grades will be phased in over coming months. Full technical data sheets on the new improved product are available to download here and here.
