With international standards such as ASHRAE 90.1, EN 14304, and local Net-Zero directives, engineers must implement insulation materials that continuously prevent heat gain, keeping energy losses to an absolute minimum.
Uninsulated or poorly insulated chilled water lines operate well below the ambient dew point. Condensation forms rapidly, leading to dripping water, damaged structural elements, and toxic mold growth within walls.
Urban density requires large-scale centralized cooling plants. Insulating miles of sub-surface and riser pipes requires closed-cell elastomeric systems with high durability and long-term thermal resistance stability.
Historically, open-cell materials like fiberglass or mineral wool were used for industrial piping. While effective for hot systems, chilled lines quickly saturated with atmospheric moisture, destroying the material's thermal properties and causing Corrosion Under Insulation (CUI).
The development of closed-cell elastomeric NBR/PVC foam (like Kingflex) revolutionized the industry. Incorporating a high water vapor resistance factor (μ ≥ 10,000), these flexible foams eliminate the need for secondary vapor barriers, keeping thermal conductivity stable for decades.
Kingflex NBR/PVC features a completely closed-cell micro-structure that traps air within tiny independent pockets, preventing moisture migration even under high relative humidity conditions.
Here we lay out the operational parameters, dimensions, and material profiles of Kingflex elastomeric insulation sheets and pipe tubes. These values are tested according to ASTM, BS, and EN international protocols.

As a premier global thermal system provider, Kingflex offers integrated system components for complex thermal, acoustic, and high-stress environments.
Non-fibrous elastomeric insulation is essential for healthcare facilities and high-precision semiconductor labs. It prevents particulate emissions and resists mold growth, keeping cleanroom air pristine.
For applications down to -200°C (such as LNG pipelines and chemical processors), Kingflex manufactures specialized multi-layered cryogenic elastomeric foams to prevent crack propagation and thermal shock.
Outdoor runs require physical protection from UV degradation, mechanical impact, and extreme weather. Kingflex laminated aluminum foil sheets provide optimal resistance for exposed roof configurations.
