Kingflex
Premium grade elastomeric rubber foam products optimized for air conditioning assemblies and global distributors.
In the wake of international decarbonization goals and the transition toward highly efficient HVAC units (driven by standard updates such as SEER2 in North America and ErP directives in Europe), air conditioner manufacturers are facing unprecedented material challenges. Heat pumps, variable refrigerant flow (VRF) systems, and multi-split cooling assemblies operate under wider thermal ranges and higher pressure fluctuations. Consequently, the quality of elastomeric insulation directly dictates the actual operational efficiency and longevity of these setups.
Traditional insulation mediums are progressively failing to meet the rigorous zero-condensation, low-outgassing, and flame-spread safety parameters demanded by modern high-density residential and commercial infrastructure. This has created a significant shift toward NBR/PVC-based closed-cell elastomeric foam, which serves as a dual-action thermal and acoustic barrier.
By retaining an incredibly low stable thermal conductivity (≤ 0.034 W/(m·K) at 0°C), Kingflex systems prevent ambient thermodynamic transfer, significantly cutting down compressor run cycles and active electricity draw.
Boasting a micro-cellular structure with closed-cell rates exceeding 98%, our elastomers exhibit massive resistance to moisture vapor diffusion, eliminating the risk of structural corrosion under insulation (CUI).
Engineered with complex halogenated flame retardants, Kingflex products comply with critical international safety indices, achieving self-extinguishing status under standard test criteria.
A professional manufacturing and trading combo for thermal insulation products, driving global HVAC innovation through deep supply integration.
Established by the esteemed Jinwei Group, which possesses a robust lineage spanning more than 40 years, Kingflex was founded in 1979 as the first pioneer manufacturer of thermal insulation materials north of the Yangtze River.
