Engineered for Condensation Control and Energy Conservation in Brazil's Diverse Climate zones
A Technical and Economic Assessment of Elastomeric Solutions in South America's Largest Economy
As Brazil's industrial infrastructure expands, particularly in the food processing, pharmaceutical, and high-rise commercial sectors of regions like São Paulo, Santa Catarina, and Rio Grande do Sul, the need for reliable thermal management is paramount. The Brazilian market is uniquely challenging; high relative humidity in coastal areas combined with tropical ambient temperatures creates extreme dew points. Under these conditions, sub-zero chilled water lines and cooling systems are highly prone to surface condensation and subsequent corrosion under insulation (CUI).
To prevent condensation and maintain high operational efficiency, HVAC designers and mechanical contractors are shifting from conventional materials like fiberglass to high-performance, closed-cell elastomeric rubber foam insulation tubes. These materials feature a high water vapor resistance factor (value $\mu \ge 10,000$), ensuring the thermal performance remains stable throughout the design lifetime of the mechanical systems.
Our elastomeric insulation solutions are systematically tested to comply with crucial national and international standards. Within the Brazilian legal and construction framework, structural projects must meet strict fire rating requirements (such as ABNT NBR 16626 classifications or equivalents). Our rubber foam tubes achieve excellent flame-spread ratings under BS 476 Part 7 (Class 1) and UL 94 (V-0, V-1) testing regimes. This ensures that in the event of an accidental fire, the material is self-extinguishing and will not generate burning droplets that could propagate fire vertically or horizontally.
Specially manufactured utilizing halogen-free compounds and flame-retardant additives. Meets UL94, BS 476, and ASTM E84 requirements for smoke density and flame propagation.
Specially blended NBR/PVC composition designed to withstand solar UV degradation, moisture ingress, and ambient industrial atmospheric chemical hazards.
Unmatched closed-cell density (40-55 kg/m³) keeps ambient moisture away from cold copper or carbon-steel piping systems, preventing structural rust.

Our commitment to rigorous testing and international standard alignment
Building insulation designs in South America, particularly in Brazil, require specific documentation confirming compliance with environmental and energy performance protocols like LEED or AQUA-HQE.
Kingflex insulation products are manufactured under strict ISO 9001:2015 quality control systems. By using highly refined NBR (Nitrile Butadiene Rubber) blended with PVC, we achieve a very stable chemical matrix. This ensures our tubes resist microbial growth, do not outgas harmful VOCs, and remain physically stable for upwards of 15 years, reducing maintenance costs for facility owners in industrial hubs like São Paulo and Manaus.
Proven energy saving installations on critical projects across the Mercosur region
Our solutions have been deployed in major automotive production centers near Campinas, food storage facilities in Paranaguá, and central air systems for large commercial centers in Rio de Janeiro. The physical toughness of our NBR/PVC blend ensures that during fast-paced structural assemblies, the tubes do not tear or suffer structural damage when pulled through tight wall spaces or industrial roof trusses.
