Explore our industrial-grade NBR/PVC closed-cell rubber foam solutions designed for superior thermal efficiency, condensation control, and acoustic damping.
Modern industrial HVAC/R and commercial refrigeration demand rigorous thermal barrier optimization. Operating temperatures of chilled water, refrigerants, and low-temperature process lines frequently plunge below dew points, setting up high risk for vapor transmission and moisture intrusion. If left unchecked, insulation degradation leads to high energy losses, systemic failure, and corrosion under insulation (CUI).
Kingflex NBR/PVC elastomeric thermal systems counter these risks by leveraging a closed-cell microstructure. With over 98% closed cells, our materials provide a built-in vapor barrier, maintaining structural dryness and a low thermal conductivity rating (λ ≤ 0.034 W/m·K at 0°C). Unlike fibrous insulation systems which require external jackets, elastomerics block vapor absorption intrinsically.
By incorporating high structural resilience and flexibility, elastomeric insulation reduces thermodynamic bridge losses across irregular piping systems, elbows, valves, and manifold joints, ensuring system longevity in critical HVAC applications.
A powerhouse in green building thermal systems with a deep foundation in engineering excellence.
Kingflex was established by the Jinwei Group, an enterprise with a storied legacy in thermal engineering. Established in 1979, the group pioneered green construction insulation materials as the very first manufacturer of thermal insulation materials north of the Yangtze River.
Located in Dacheng, China—a designated capital of green-building insulation technology—Kingflex research, development, and production plants cover a broad industrial footprint. We handle full consultancies, R&D trials, dynamic factory configurations, and onsite project installation support for construction and industrial systems globally.
Today, the company acts as a designated supplier of critical insulation components for the Ministry of Energy, Ministry of Chemical Industry, and Ministry of Electric Power, validating our products' safety, longevity, and stability.
At the core of Kingflex is a highly specialized team focused on advanced polymer physics and thermal engineering. Our R&D department features 8 professional chemical engineers dedicated to enhancing materials' mechanical properties, flame retardancy, and low-temperature flexibility.
Our international client support team consists of 6 dedicated international sales managers, supported by 230 manufacturing specialists who operate under stringent ISO 9001 and ISO 14001 guidelines to maintain uniform product properties.
Our continuous investments in automated extrusion technology ensure minimal thickness variation, uniform foaming density, and optimal thermal performance across every production batch.
Kingflex products are certified to meet global building code requirements, marine standards, and cleanroom regulations.
Complies with BS 476 Parts 6 & 7 (Class 0 / Class 1), UL 94 V-0 flame ratings, and ASTM E84 surface burning test standards, displaying self-extinguishing safety properties.
Strictly compliant with EU REACH and RoHS environmental directives. Our insulation products are manufactured without CFC, HCFC, or HFC blowing agents, achieving zero Ozone Depletion Potential (ODP) and zero Global Warming Potential (GWP).
Every roll and tube undergoes quality-control batch printing, offering complete production-line tracking from raw polymer input to final packaging.
Engineered to perform in complex environments, from commercial offices to deep-sea cryogenic operations.
Thermal control for air ducting systems and chilled water pipelines in airports, hotels, shopping centers, and medical centers to prevent condensation and optimize compressor performance.
Proprietary multi-layer cryogenic thermal systems designed to insulate low-temperature pipelines and liquid storage tanks down to -196°C, maintaining fluid temperatures in LNG and chemical facilities.
Utilizing open-cell elastomeric panels and multi-density layers to dampen structure-borne noise in mechanical rooms, duct lines, compressor assemblies, and passenger rail cabins.
Over the years, Kingflex has established strong distribution networks in more than 66 countries. Our global B2B partnerships are built on transparency, prompt quotation processes, and consistent quality.
Transparency is core to our operations. See client communications and logistics screenshots reflecting our customer-first service.
