Cost-Effective Replacements for HCFC 141b for Panel

Improve Thermal and Environmental Performance

Insulated metal panels (IMPs) are typically formed with polyurethane (PUR) or polyisocyanurate (PIR) foam sandwiched between two metal sheets to make composite roof, wall, and partition panels. Our blowing agents improve foam performance in IMPs. Solstice® LBA is also ideally suited as an alternative to isopentane for PIR board applications in residential and commercial buildings.

Low Global Warming Potential (GWP) Blowing Agent

With its outstanding thermal performance and a GWP of 1, Solstice Liquid Blowing Agent (LBA) is a balanced solution to today’s environmental and performance challenges in insulated metal panel applications.

Solstice LBA delivers unique performance advantages in a variety of applications:

Superior Insulation Performance

  • Increases R-value of conventionally processed PUR and PIR foam in both continuous and discontinuous panel operations
  • Up to 2mW improvement compared to pentane blown boards
  • Translates to a thinner panel to achieve desired performance

Low GWP

  • GWP of 1
  • Supports compliance with current and future environmental regulations

Advanced Physical Properties, Mechanical Stability, and Nonflammability

Solstice LBA shows:

  • Improved thermal performance
  • Proven nonflammablility
  • Significantly better dimensional stability at high temperatures than systems formulated with pentanes or HFC-134a
  • Higher compressive strength than IMPs formulated with pentane, HFC-134a or HCFC-141b

Ease of Use

  • “Drop-in” replacement for conventional panel processing equipment
  • Working with major systems producers to ensure required testing and data is available to meet most applications
  • Requires no investment in plant equipment to meet flammability or other special concerns
  • Straightforward and cost-effective transitions

Enovate 245fa blowing agent provides discontinuous and continuous IMP manufacturers with a wide range of processing and performance benefits. It’s an ideal replacement for HCFC-141b, HCFC-22, and other foam blowing agents providing many benefits including:

Greater Energy Efficiency

  • 10% higher R-value (at 30°F / -1°C) compared to hydrocarbon-blown panels in internal tests

Greater Dimensional Stability and Durability

  • Will not condense in foam as the temperature drops in typical cold storage applications (Panels formulated with other foam blowing agents experience condensation, which can lead to dimensional stability issues in the finished panel.)
  • Panel durability further enhanced by excellent adhesion to metal skins and compressive strength

Regulatory Compliance

  • Meets Montreal Protocol requirements
  • Supports compliance with phase-out of HCFC-141b

Minimal Conversion Costs

  • Rapid deployment
  • “Drop-in” replacement*

* Minor equipment modifications may be necessary, depending on how current foam blowing agent is stored and routed through facility

Excellent Processing with Favorable Cost Implications

  • Excellent flow properties
  • Good solubility in polyols
  • Potential foam density reductions
  • Possible waste reduction due to ease of processing

Improved Environmental and Safety

  • Nonflammable (ASTM E-681, EU A11)
  • Non-ozone-depleting
  • VOC-exempt (per U.S. EPA)
  • Foam cores blown with Enovate meet the ASTM E-84 Class 1 specification
  • Foam cores blown with Enovate require no special handling during installation

Some examples of panel applications include:

  • Architectural panels
  • Walk-in freezers
  • Reefers (refrigerated containers)
  • Cold storage
  • Refrigerated trailers
  • Emergency shelters
  • Modular school classrooms
  • General structural insulation
