View Technical ParametersOperating HVAC&R systems and industrial manufacturing plants in Vietnam demands materials that withstand extreme microclimates. With average relative humidity levels routinely exceeding 85% to 90% in economic epicenters like Hanoi, Bac Ninh, and Ho Chi Minh City, the risk of condensation (sweating) on cold pipelines and air ducts is severe. Condensation leads to dripping ceilings, systemic water damage, structural mold growth, and a critical reduction in plant efficiency due to wet insulation.
For engineering procurement, selecting the right elastomeric NBR/PVC foam requires understanding the physics of thermal boundaries in tropical environments. Kingflex NBR/PVC thermal insulation products offer a combination of an ultra-low thermal conductivity (λ ≤ 0.034 W/m·K at 0°C) and an extremely high moisture resistance factor (μ ≥ 10,000). This high-density, closed-cell barrier prevents the penetration of ambient air moisture into the material core, protecting the thermal insulation properties over an estimated lifecycle of 10 to 15 years.
Unlike open-cell alternatives such as rock wool or glass wool, which act like a sponge when exposed to humid air, elastomeric rubber foam maintains its structural and thermal integrity.

Where and how Kingflex high-performance elastomeric insulation is specified across building systems and process networks.
Wrapped around duct surfaces, Kingflex sheet rolls prevent heat transfer between ambient spaces and chilled air streams. This reduces chiller load demand, eliminates ceiling sweating, and dampens mechanical vibration noise.
Pre-formed elastomeric pipes insulate copper and steel lines running from condensing units to fan coils, preventing energy losses in tropical weather.
Dust-free and fiber-free, our NBR/PVC foam emits no particles. This makes it ideal for electronics manufacturing plants, cleanrooms, and food processing lines.
Complete technical collection available for container-level delivery, meeting building and industrial safety regulations.
Technical clarifications for structural designers, quantity surveyors, and project managers regarding importation, performance, and standard compliance.
Vietnam experiences relative humidity up to 90%. Under these conditions, lower-grade or open-cell insulation materials absorb moisture, leading to a loss in thermal resistance. Kingflex closed-cell NBR/PVC foam features a high water vapor resistance factor (μ ≥ 10,000), preventing moisture entry and maintaining long-term insulating properties.
Yes. Kingflex rubber foam insulation products contain built-in fire-retardants that meet BS 476 (Class 0 and Class 1) and UL 94 (V-0 rating) standards, complying with the fire safety guidelines for building and industrial projects in Vietnam.
Rubber foam is flexible and moisture-resistant, making it ideal for HVAC ducts and cold piping. Rock wool is a fibrous material with high-temperature resistance, suited for hot-process pipelines in power plants and industrial systems.
Yes. We support custom OEM production to meet your requirements. We can adjust the density, color, self-adhesive backing, and foil lamination for sheet rolls or pipe profiles according to your design specifications.
