Explore our high-performance closed-cell elastomeric foam tubes, sheets, and cryogenic systems configured for dynamic energy savings.
Why large-scale engineering projects mandate exact 19mm (3/4 inch) elastomeric closed-cell foam sheets for moisture barrier and thermal stability.
Condensation control is the paramount target in HVAC and refrigeration. The 19mm thickness serves as the structural sweet spot for chilled water pipes and high-humidity ducts, protecting ceiling grids and critical IT server rooms from costly water damage.
Due to the dual-density formulations of our NBR/PVC compound, 19mm flexible sheets absorb mid-to-high frequency vibration. Our sheets substantially reduce structural noise within cleanrooms, medical centers, and complex marine machinery spaces.
By implementing a 19mm structural insulation barrier, pipeline thermal losses are mitigated by up to 87.5% compared to non-insulated surfaces. This translates to direct carbon footprint reduction and enables projects to achieve LEED or BREEAM certifications.

Where and why the 19mm NBR/PVC elastomeric rubber foam sheets are non-negotiable across global supply systems.
Large commercial shopping malls, high-rise luxury hotels, and critical healthcare systems rely on 19mm sheet rolls wrapped around massive supply air ducts. This eliminates condensation dripping above suspended ceilings and ensures long-term operational efficiency.
At ultra-low storage temperatures, structural expansion and contraction are violent. Our high-performance cryogenic elastomeric sheet foam preserves temperatures down to -196°C in LNG tanks, reducing gas boil-off rate (BOR).
In high-speed trains and ship engine rooms, passenger safety demands structural materials with extreme resistance to fire propagation. Kingflex 19mm sheets deliver Class 0 fire ratings, limiting toxic gas emissions during thermal events.
Kingflex operates advanced, green-building material production plants in Dacheng, China, satisfying large-volume schedules.
Kingflex Insulation Co., Ltd. is proud to be a designated enterprise for the Ministry of Energy, Ministry of Electric Power, and Ministry of Chemical Industry in China. This validation underscores our manufacturing quality controls and volume stability.
Every single batch of Kingflex 19mm sheets is tagged with an end-to-end trace barcode. Engineers can map batch density, fire lab test records, and raw NBR/PVC ratio inputs, securing compliance against structural failures.
Kingflex R&D features deep industrial testing equipment to assure structural conformance to ASTM, CE, and RoHS standards.











Adapting Kingflex insulation products to the strict ecological standards of North American and European markets.
Kingflex is refining its technical production methods toward Zero Halogen formulations (halogen-free compounds). By omitting chlorine and bromine agents, we eliminate corrosive fumes and toxic acid outgassing during active smoke events.
Our raw NBR polymers and plasticizer compounds pass stringent REACH and RoHS audits. This assures project compliance in EU construction zones, freeing developers from health liability worries regarding volatile organic compounds (VOCs).
For cleanroom environments and food production facilities, our NBR structure features optional anti-bacterial barriers. This thwarts mold propagation inside dark, damp spaces, ensuring long-term air quality.
Proven applications across major industrial centers, manufacturing complexes, and public engineering infrastructures.
