TRYMER® Polyisocyanurate Insulation

TRYMER® polyisocyanurate pipe insulation is a closed-cell, high-performance insulation for pipe, vessel, equipment and duct applications. ITW Insulation Systems offers a complete line of TRYMER pipe insulation products in a selection of densities and compressive strengths. TRYMER pipe insulation features one of the lowest ambient k-factors among all pipe insulations: 0.19 BTU · in/hr · ft2 · °F at 75°F mean temperature (0.027 W/m · °C at 24°C) and can be used over a broad temperature range from -297°F to 300°F (-183°C to 148°C).

In addition to superior thermal conductivity (low k-factor and high R-value), TRYMER PIR products feature:

  • Very good flame spread/smoke developed performance
  • Closed-cell and non-fibrous structure
  • Exceptional moisture resistance (to both liquid and vapor)
  • Strength and durability
  • Fabrication ease
  • Ease of installation and maintenance
  • Effective coverage of elbows and fittings
  • Long life span
  • Low initial and life-cycle cost
  • Excellent chemical resistance
  • Hydrocarbon blowing agents, which have no ozone-depletion potential
