Additional Details

Polyurethane insulations, briefly known as PUR, are considered among rigid closed-cell cold insulations.

Polyurethane is available in prefabricated slabs and can also be injected in bulk or sprayed on site. If polyurethane is sprayed (SPF – Spray applied Polyurethane Foam), special equipment is required and the presence of trained personnel is essential for the best results. SPF is mostly used in liquid transmission lines, tanks and vessels, cold storage centers and cold rooms, coolers and freezers. One of the main applications of polyurethane is the insulation used in sandwich panels.

In addition to insulation applications, polyurethane has many diverse uses in industry; for example, polyurethane is used in the manufacture of anti-wear elements such as anti-abrasion rollers, supports, and elements under compressive forces, rigid plastic parts, wheels, and so on. Polyurethanes used in different sectors differ from each other in density and chemical composition percentage. Polyurethane (PUR) insulations are very similar to polyisocyanurate (PIR) insulations and have almost the same properties and chemical composition.

Polyurethane insulations are available on the market in prefabricated board, pipe, and half-pipe forms. Polyurethane can also be injected or sprayed on site.

The ASTM C 1029 standard, titled “Sprayed Cellular Polyurethane Thermal Insulation,” covers topics related to various physical properties and applications of this material as thermal insulation in the range of -30 to 107 °C.

The above standard also discusses requirements for thermal resistance for 1 inch, compressive strength, water vapor permeance, water absorption, tensile strength, response to thermal and moisture aging, and closed-cell content.

The density of polyurethane is highly varied and changes depending on the type of need and application of the product.

Advantages of Polyurethane Insulations

• Very low thermal conductivity coefficient, highly suitable for industrial applications
• High resistance to erosion and corrosion
• High resistance to acids, solvents, and moisture
• High resistance to microbial, fungal, and biological contamination
• Capability of changing density from 30 kg/m³ to 700 kg/m³
• Suitable injectability and formability for insulating complex, bulky, or hard-to-reach shapes

Disadvantages of Polyurethane Insulations

• If injection-type polyurethane is required, a trained operator and equipment are essential.
• If the operating temperature exceeds the allowable temperature range, the thermal resistance of polyurethane decreases sharply.
• It is flammable and produces toxic gases if it catches fire. It is dusty (prefabricated polyurethane blocks and shapes are dusty and generate dust).
