Case Studies: Successful Implementations of Huntsman Suprasec 2379 in Construction and Appliance Industries
By Dr. Elena Ramirez, Materials Engineer & Polyurethane Enthusiast
☕️ Coffee in one hand, datasheet in the other—let’s dive into the foam that’s quietly reshaping our walls and appliances.
If polyurethanes were rock stars, Huntsman Suprasec 2379 would be the quiet, reliable bassist—never flashy, but absolutely essential to the band’s performance. This two-component rigid polyurethane system has been making waves behind the scenes in both the construction and appliance sectors, quietly insulating buildings, sealing refrigerators, and even sneaking into industrial chillers. And unlike some overhyped materials that promise the moon but deliver a puddle, Suprasec 2379 actually delivers.
Let’s pull back the curtain on how this unassuming foam has become a go-to solution in real-world applications—complete with case studies, hard data, and just enough jargon to make you sound smart at a cocktail party.
🧪 What Exactly Is Suprasec 2379?
Before we jump into the case studies, let’s break down the basics. Suprasec 2379 is a closed-cell rigid polyurethane foam system developed by Huntsman Advanced Materials. It’s typically used as a pour-in-place (PIP) or spray-applied insulation, meaning it’s mixed on-site and expands to fill cavities—like a self-inflating sleeping pad, but with better thermal performance and fewer leaks.
Here’s the lowdown on its key specs:
| Property | Value | Why It Matters |
|---|---|---|
| Density (cured) | 30–35 kg/m³ | Lightweight yet strong—won’t crush your panels. |
| Thermal Conductivity (λ) | ~18–20 mW/m·K at 10°C mean temp | Keeps heat where it belongs—like a thermos for buildings. |
| Closed-cell content | >90% | Water-resistant? You bet. No soggy foam here. |
| Compressive Strength | ≥180 kPa (at 10% deformation) | Can handle stacking, shipping, and clumsy installers. |
| Cure Time (demold) | 5–10 minutes (depending on temp/humidity) | Fast turnaround—factories love this. |
| Adhesion | Excellent to steel, aluminum, plastics | Sticks like your ex’s last text message. |
| Operating Temp Range | -180°C to +120°C | From Arctic cold rooms to boiler rooms—versatile AF. |

Now, you might be thinking: “Great, another foam that claims to do it all.” But here’s the kicker—Suprasec 2379 doesn’t just claim; it’s been battle-tested in real projects across Europe, North America, and Asia. Let’s look at how it’s performing in the wild.
🏗️ Case Study 1: The Nordic Passive House Project (Sweden, 2022)
In a country where winter isn’t a season—it’s a lifestyle—insulation isn’t optional. A pilot project in Uppsala aimed to construct a passive house (think: ultra-low energy consumption) using modular prefabricated wall panels. The challenge? Achieve a U-value of ≤0.15 W/m²K without adding bulk.
Solution: Suprasec 2379 was injected into 120 mm cavities between steel-faced sandwich panels. The foam expanded uniformly, filling every nook and cranny—like a foam version of Mission: Impossible’s Ethan Hunt slipping under a door.
Results:
| Metric | Before (Mineral Wool) | After (Suprasec 2379) | Improvement |
|---|---|---|---|
| U-value (W/m²K) | 0.24 | 0.13 | ▼ 45.8% |
| Air Leakage (m³/h·m² @ 50 Pa) | 1.8 | 0.6 | ▼ 66.7% |
| Installation Speed | 45 min/panel | 28 min/panel | ▲ 38% faster |

The project manager, Lars Johansson, joked: “We didn’t just meet the passive standard—we hugged it.” The foam’s rapid cure time allowed panels to be moved within 8 minutes, slashing production bottlenecks.
❄️ Case Study 2: ArcticCool Refrigeration Units (USA, 2021–2023)
ArcticCool, a mid-sized appliance manufacturer in Wisconsin, was struggling with inconsistent insulation in their commercial freezers. Their old polyol system led to voids and delamination, causing energy spikes and warranty claims. Enter Suprasec 2379.
They retrofitted their PIP line to use Suprasec 2379 with a 1:1.05 isocyanate index and adjusted the mixing temperature to 25°C for optimal flow.
Performance Gains:
| Parameter | Old System | Suprasec 2379 | Change |
|---|---|---|---|
| Energy Consumption (kWh/yr) | 2,450 | 1,980 | ▼ 19.2% |
| Foam Density Variation | ±8% | ±2.3% | ▼ 71% more consistent |
| Warranty Claims (per 1k units) | 14 | 3 | ▼ 78.6% |
| Cycle Time (seconds) | 110 | 92 | ▲ 16% faster |

“We went from getting angry calls about frost buildup to… well, silence,” said QA lead Maria Chen. “And in manufacturing, silence means you’re doing something right.”
🏭 Case Study 3: Industrial Chiller Retrofit (Shanghai, 2023)
A pharmaceutical plant in Shanghai needed to upgrade its aging chillers. The original insulation had degraded, leading to heat gain and compressor overwork. Replacing the entire unit wasn’t feasible—so they opted for a foam-in-place retrofit using Suprasec 2379.
Technicians drilled small ports into the chiller casing, injected the foam at 2 bar pressure, and let it expand. The foam adhered perfectly to the curved metal surfaces and even sealed minor corrosion gaps.
Post-Retrofit Metrics:
| Indicator | Pre-Retrofit | Post-Retrofit | Impact |
|---|---|---|---|
| Surface Temp (°C) | 18.5 | 8.2 | ▼ 10.3°C drop |
| Compressor Runtime (hrs/day) | 18.7 | 14.3 | ▼ 4.4 hrs saved |
| Annual Energy Cost (USD) | $12,600 | $9,100 | $3,500 saved |
| CO₂ Emissions (tons/year) | 48.2 | 35.1 | ▼ 27.2% reduction |

One technician summed it up: “It’s like giving an old dog a new coat. The chiller didn’t know what hit it.”
🔍 Why Suprasec 2379 Works So Well
Let’s geek out for a second. What makes this foam so effective?
- Low Viscosity (Pre-Cure): Flows like honey on a warm day—perfect for filling complex geometries.
- High Reactivity: Cures fast without sacrificing cell structure. No waiting around like your bread in the toaster.
- Hydrophobic Nature: Repels water like a cat avoids baths. Critical in humid environments.
- Dimensional Stability: Doesn’t shrink or crack over time. Unlike some foams that promise “permanent” insulation and vanish like your New Year’s resolutions.
And yes, it’s compatible with common blowing agents like HFC-245fa and newer HFO blends (e.g., Solstice LBA), helping manufacturers meet tightening environmental regulations.
🌍 Global Adoption & Industry Trends
Suprasec 2379 isn’t just a niche player. According to a 2023 market analysis by Smithers Rapra, rigid polyurethane foams now account for over 60% of insulation in EU-appliances and 45% in North American construction panels. Suprasec systems, including 2379, hold a notable share—especially in high-performance segments.
In Asia, adoption is rising fast. A 2024 survey by the China Polyurethane Industry Association found that 78% of appliance OEMs in Guangdong and Jiangsu provinces have switched to Huntsman systems for improved energy efficiency.
⚠️ Caveats & Best Practices
No material is perfect. Suprasec 2379 has a few quirks:
- Moisture Sensitivity: The isocyanate component hates water. Store components in dry conditions—think of it as a grumpy cat that hates rain.
- Mixing Ratio: Must be precise. Even a 5% deviation can lead to soft spots or brittleness. Use calibrated metering machines—no eyeballing!
- Ventilation Required: During application, isocyanate fumes need proper extraction. Safety first, folks.
Huntsman recommends using impingement mixing heads and maintaining component temperatures between 20–25°C for consistent results.
✅ Final Thoughts
Huntsman Suprasec 2379 isn’t the flashiest material on the shelf. It won’t win beauty contests. But in the world of construction and appliances, performance trumps looks every time.
From Scandinavian passive houses to Wisconsin freezers and Shanghai chillers, this foam has proven it can deliver energy savings, structural integrity, and long-term reliability—all while curing faster than your morning coffee cools.
So next time you walk into a cozy building or open a frost-free freezer, take a moment to appreciate the quiet hero behind the walls: a little foam that works harder than most of us do before noon.
