What is the temperature range for polyurethane?

• A. -330*F to 200*F
• B. 0*F to 160*F
• C. -100*F to 100*F
• D. -500*F to 250*F

Answer: (A)

Polyurethane insulation is designed to perform over a very wide temperature span, from extremely cold to moderately warm environments. The low end around -330°F shows it can withstand cryogenic conditions without losing its cellular structure or becoming brittle, which is why it’s used in applications like cryogenic vessels and cold-weather piping. The high end around 200°F (about 93°C) indicates it remains stable and continues to insulate effectively up to those temperatures; beyond that, the foam can soften, degrade, or release blowing agents, reducing its performance. This combination of cold toughness and heat tolerance makes this range the best fit for polyurethane.
