TRYMER™

TRYMER™ polyisocyanurate pipe insulation is a closed-cell, high-performance insulation for pipe, vessel, equipment and duct applications. Dow 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 polyisocyanurate pipe insulation 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
