Elastomeric Rubber Foam Insulation: Superior HVAC Performance
Elastomeric Nitrile Rubber (NBR) Insulation is a premier thermal lagging solution engineered with a closed-cell micro-cellular structure, outstanding elasticity, and high water vapor diffusion resistance. It is the material of choice for modern heating, cooling, air conditioning (HVAC), chiller circuits, and fluid distribution networks designed to achieve peak energy efficiency, eliminate thermal gains/losses, and prevent condensation.
With a low thermal conductivity rating (λ ≤ 0.034 W/m·K), it maintains strict thermal control while eliminating the risk of corrosion under insulation (CUI) on metallic pipework and sheet-metal ducts. Available in flexible tube and sheet formats—with self-adhesive backing, reinforced aluminum foil, or heavy-duty jacketing options—it ensures swift fabrication and seamless insulation even in tight spatial clearances.
Key Features
- Closed-Cell Structure: Superior water vapor permeability resistance (μ ≥ 7,000) providing permanent anti-sweat and corrosion protection
- Low Thermal Conductivity: Exceptional thermal insulation properties reducing energy expenditure in heating and chilled systems
- Fire Safety Compliance: Self-extinguishing, flame-retardant formulation meeting EN 13501-1 (B/B-L, s3, d0) fire safety criteria
- High Flexibility & Fast Installation: Conforms smoothly over bends, valves, flanges, and fittings without tearing or cracking
- Broad Operating Range: Dependable continuous thermal stability spanning from -50°C to +105°C (+150°C for high-temp grades)
- Multiple Formats: Continuous rolls and pre-slit tubes; available with self-adhesive backing, aluminum foil, or reinforced claddings
Application Fields
- Central HVAC air distribution networks (rectangular sheet-metal and spiral spiro ducting)
- Chilled water distribution lines, chiller circuits, and fan coil unit (FCU) hookups
- Domestic hot water lines, boiler plant piping, and hydronic heating systems
- Industrial process refrigeration, chemical piping, and storage tank insulation
- VRF/VRV copper refrigerant line insulation and internal equipment casing linings
