STYROFOAM Brand Insulation is manufactured by expanding molten polystyrene in a continuous extrusion process to form a rigid, closed-cell foam with uniform, void-free, micro-cellular structure. This structure gives STYROFOAM Brand Insulation its high compressive strength. Also, it gives the foam its excellent resistance to water, resistance to water vapor, and even resistance to wet freeze-thaw cycling. Consequently, STYROFOAM brand insulation is able to keep insulating, despite the high moisture conditions which exist continually in low temperature operations - conditions which can cause lesser insulation products to absorb moisture and lose insulating ability.

Preventing Condensation

Corrosion and dripping are the typical problems associated with condensation occurring on equipment and piping. To elimination condensation, the insulation system must be designed to maintain a surface temperature above the dewpoint temperature of the ambient air during the most severe temperature and humidity conditions that can be anticipated. In addition, an effective vapor barrier should installed over the insulation to prevent vapor from penetrating the open joints of the insulation.

Chemical and Environmental Resistance
STYROFOAM brand Pipe Insulation Billet has no food value to attract or support plant or animals life. Exposure to direct sunlight for extended periods of time can result in ultra-violet degradation of the surface. Signs of UV degradation are yellowing of the surface, followed by the formation of a thin layer of dust. the dust can inhibit the bonding of mastic coatings and sealants, and it should be removed by thorough brushing before application of such materials.

STYROFOAM brand Pipe insulations Billet has excellent resistance to acids, basses, brines and alcohol. It has poor resistance to hydrocarbons. olefins, napthas, ketones and vinyl esters.

Lowest Pipe Temperature Limits to Prevent Condensation.
Tables pertaining to minimum operating temperatures for pipe diameter/insulation thickness combinations and which condensation can be expected to occur for the different ambient conditions are available to determine the effect when one ambient conditions changes. Email an Extol representative.
