STYROFOAM Brand Pipe Insulation Billet for Low Temperature Applications
|
 STYROFOAM Brand Insulation has enjoyed a long and successful history in low temperature applications. For over 40 years it has been used to insulate refrigerated buildings, refrigerated trucks, and refrigeration equipment and piping. The key to this success has been the excellent performance of STYROFOAM Brand Insulation. It has exceptional moisture resistance, so it keeps its insulation value long term. And it has high compressive strength to resist physical damage. For many industrial firms, STYROFOAM Brand Pipe Insulation over the years has become the preferred insulation for their low temperature systems, both for preventing surface condensation and for minimizing heat gain.
Product Description:
STYROFOAM Brand Pipe Insulation Billet is manufactured in various sizes please contact Extol for details. It is specifically formulated for easy fabrication into such shapes as pipe covering, valve and fitting covers, and equipment lagging. Common fabrication techniques include hot wire cutting, sawing, routing, and planing. The resultant fabricated sections are non-dusting and non-inflating and are easily installed.
Moisture Resistance and Insulation Value:
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.

(1) All properties are measured at 74°F, unless otherwise indicated.
(2) Unless otherwise, indicated, data shown are typical values obtained from representative production samples. This data may be used as a guide for design purposes, but should not be construed as specifications. For property ranges and specifications, CLICK HERE.
(3) Average value through foam cross section.
(4) Above 165°F(74°C), discoloration and charring will occur, resulting in an increased k-factor in the discolored area.
(5) Frequent and severe thermal cycling can produce significant dimensional changes. Special design considerations must be made in systems that cycle frequently.
