DuPont™ Styrofoam™ Brand Pipe Insulation Billet

High R-value, Versatile Billet for Pipe Insulation Applications

U.S. HFC Regulation Compliant Formulation

Styrofoam™ Brand XPS Pipe Insulation Billet is used extensively in industrial and commercial piping applications. With a service temperature range of -320 °F to 165 °F (-196 °C to 74 °C), Styrofoam™ Brand XPS Pipe Insulation Billet is a preferred material for low-temperature systems, both for minimizing heat gain andpreventing surface condensation.

Styrofoam™ Brand XPS Pipe Insulation Billet maintains its key insulating properties in low temperature applications and other environments with high humidity and high-moisture conditions.

Styrofoam™ Brand XPS Pipe Insulation Billet is specifically formulated for easy fabrication into many shapes, such as pipe coverings, valve and fitting covers, and others to meet specific design needs. Because of the critical design aspects in many applications, DuPont recommends contacting qualified designers for system design.

¹Values are consistent with the criteria of ASTM C578 and the requirements of the FTC R-value rule (16 CFR Part 460). R means resistance to heat flow. The higher the R-value, the greater the insulating power.

²Vertical compressive strength is measured at 10 percent deformation or at yield, whichever occurs first. Since Styrofoam^™ Brand Extruded Polystyrene Foam Insulations are visco-elastic materials, adequate design safety factors should be used to prevent long-term creep and fatigue deformation.

³Based on 1” thickness.
