Kingflex
Modern building construction and industrial process engineering require high-performance materials that optimize thermal efficiency while ensuring strict compliance with fire and environmental regulations. Black Color Rubber Foam Insulation Sheet Rolls, primarily formulated from a balanced Nitrile Butadiene Rubber (NBR) and Polyvinyl Chloride (PVC) matrix, represent the pinnacle of closed-cell elastomeric technology.
The performance of Kingflex elastomeric materials is determined by their microscopic structure. With a closed-cell rate exceeding 98%, these sheets effectively trap microscopic air pockets, preventing convective heat transfer. Furthermore, this structure functions as an integrated vapor barrier, preventing moisture intrusion and protecting pipelines against Corrosion Under Insulation (CUI).
Whether utilized in HVAC ductwork, chilled water pipes, or ultra-low temperature (ULT) cryogenic facilities, this material delivers long-term thermal stability across a broad temperature range of -40℃ to 105℃, resulting in energy savings and reduced operational costs.
Our rubber foam products are tested to rigorous international standards. Below is the technical data matrix for the Kingflex Standard Black Color Rubber Foam Insulation Sheet & Roll.
