ISO-C1®/6.0 Polyisocyanurate Insulation
6.0 lb/ft3 (96 kg/m3) density
ISO-C1/6.0 is Dyplast Products’ 6.0 lb/ft3 polyisocyanurate rigid, closed cell, foam insulation. ISO-C1/6.0 physical properties is certified by independent laboratories. ISO-C1/6.0 is ideally suited for low temperature piping and refrigeration applications where added compressive, shear, flexural, or tensile strength beyond that available in 4.0 lb/ft³ polyiso is appropriate. ISO-C1/6.0, for example, is well suited for pipe saddle applications where superior insulating properties combine with excellent compressive strength.
Dyplast Products offers ISO-C1/6.0 as variable-sized bunstock or as sheets and blocks with tolerances to 1/32 inch. Our extensive network of fabricators can provide special shapes for pipe, fittings, vessels, or other mechanical applications.
Polyisocyanurate exhibits the highest R-factor (insulating value) to thickness ratio of commercially available insulation, and our ISO-C1 product line provides higher R-factors and reduced thermal aging at lower temperatures. Ideal for low-temperature and cryogenic applications, ISO-C1 offers superior performance when compared to polystyrene, polyurethane, phenolic, fiberglass, and cellular glass alternatives. Our ISO-C1 product line is also available in 2, 2.5, 3, and 4 lb/ft3 densities, which each provide successively improved strength and other attributes for physically demanding applications.
Dyplast Products offers mechanical insulation solutions for an array of low temperature applications such as LNG insulation, cryogenic insulation, chilled water pipe insulation, refrigeration insulation, and low temperature steam insulation - - and in industries ranging from building construction, roofing, refrigeration, transportation, petrochemical, pharmaceutical, marine, and more.
ISO-C1/6.0 is designed for use where temperatures range from -297F to +300F, making ideal for refrigeration and freezers, commercial HVAC and chill water systems, cryogenic processes such as LNG and LOX, panel insulation for transportation containers, duct and air plenum insulation, and core material for architectural and panel construction.
WATER ABSORPTION (WA)
Water absorption by insulation can degrade thermal insulating performance, although the correlation between WA and loss of thermal efficiency varies considerably between insulants. ISO-C1/6.0’s extraodinary resistance to water absorption (0.6%) helps ensure long-term thermal performance, and remains superior to polystyrenes, phenolic foams, and fiberglass. Proper installation of vapor barriers can further improve performance of the complete ISO-C1/6.0 insulating system.
With its high R-factor, ISO-C1/6.0 can achieve the same insulating value with as little as half the thickness required by alternative insulating materials. Less insulation leads to thinner walls, more space, and fewer and tighter energy-losing seams - - further enhanced by the availability of larger pieces (for example, 24-foot lengths). Less insulation in mechanical applications also equates to reduced quantities of expensive vapor retarders, jackets, and mastics. The lighter weight of ISO-C1/6.0 compared to cellular glass reduces structural support requirements.
High thermal insulation efficiency is achieved by infusing cells with gases having low thermal conductivity. All such rigid foam insulation (including polyurethane, extruded polystyrene, and polyisocyanurate) thus lose a small amount of their insulating value over time as air displaces insulating gases. ISO-C1/6.0’s smaller, stronger cell structure and our proprietary cell-gas formulation work together to impede gas transfer across cell boundaries, thus reducing loss of thermal efficiency. It is important to note that ISO-C1/6.0’s service temperatures is normally well below 75F, and that thermal aging is reduced considerably at lower operating temperatures. Thicker insulation, vapor barriers, and metal constraints also limit gas diffusion.
