As electricity prices continue to rise and green-building regulations become stricter, the application of polyurethane (PU) in spray and pour foam insulation has become the No. 1 choice for construction projects, cold storage facilities, insulated panels, and industrial piping systems. With an outstanding thermal conductivity coefficient of only 0.018–0.028 W/m·K, PU foam insulation can reduce energy costs by up to 50% while contributing to environmental protection.

This article will help you understand:

• What polyurethane PU is and why it dominates the insulation market
• The most popular real-world applications in Vietnam today
• Superior advantages compared to rock wool and EPS
• Professional spray/pour foam application process
• And most importantly: Vietnam’s most trusted PU supplier – JM Enterprise

What is Polyurethane PU? Why is it the “King” of Insulation?

Polyurethane PU (also known as rigid PU foam) is created through a chemical reaction between Polyol and Polymeric MDI (Isocyanate). When these two components meet under proper pressure and temperature, they expand 30–40 times in volume, forming a closed-cell rigid foam that traps insulating gas inside.

Outstanding properties:

• Lowest thermal conductivity among common insulation materials
• High mechanical strength and excellent compression resistance
• 98–99% water resistance, anti-moisture, anti-mold
• Lifespan > 50 years (certified by global giants like BASF, Huntsman)

Most Popular PU Foam Insulation Applications in Vietnam

1. Cold storage & refrigerated containers → Foam thickness 80–200 mm, maintains temperature from -40°C to +80°C → Saves 30–40% electricity for refrigeration
2. Insulated sandwich panels for factories & pre-engineered buildings → 50–150 mm PU panels completely replace traditional steel + rock wool
3. Roof, wall, and concrete floor insulation → Direct spray or pour-on-site, seamless, no cold bridges
4. Hot/cold water and industrial pipe insulation → PU pipe covers or direct on-site spraying
5. Automotive, marine, and railway vehicles → Sound and thermal insulation for engine compartments and seats (used by VinFast, Hyundai Thành Công)
6. Commercial freezers and refrigerators → High-density PU system 38–42 kg/m³

Professional PU Spray/Pour Foam Insulation Process

1. Site survey & formulation consultation
2. Surface cleaning and preparation
3. Accurate mixing of Polyol + MDI using high-pressure machines (Graco, Gama…)
4. Spray or pour foam (full expansion in 15–30 seconds)
5. Trimming and surface finishing
6. Thickness and thermal conductivity verification
