Engineered to mitigate thermodynamic degradation, prevent surface condensation, and comply with strict fire code mandates worldwide.
An in-depth thermodynamic analysis of closed-cell elastomeric structures, moisture protection barriers, and structural energy savings.
Maintains thermal conductivity ($\lambda$) ≤ 0.034 W/m·K at 0°C. Reduces thermal gains or losses in refrigerant lines and chilled water pipe networks.
With a vapor resistance index ($\mu$) ≥ 10,000, our NBR/PVC blend limits water ingress. This keeps thermal performance stable even in humid process spaces.
Tested under BS 476 (Part 6 & 7 Class 0) and UL 94 V-0, ensuring low flame spread and minimal toxic smoke emission in commercial applications.
Kingflex Insulation Co., Ltd. operates state-of-the-art continuous vulcanization extrusion lines, serving industrial sites in 66+ countries.
Kingflex Insulation Co., Ltd.
Located in Dacheng, China's well-known capital of green building materials, Kingflex runs an energy-saving, environmentally friendly enterprise. We integrate product development, engineering, and sales. We design solutions for insulation systems, offering support from initial technical design up to construction site guidance and after-sales inspections.
Our parent group, Jinwei Group, established in 1979, has a 40+ year history and was the first manufacturer of thermal insulation materials north of the Yangtze River. Today, the facility has 230 production workers, 8 R&D engineers, and a professional international sales team.

We focus on developing next-generation insulation options, such as low-GWP, zero-ODP halogen-free blowing agents. Additionally, our engineering group works on aerogel-infused rubber foam sheets. These materials offer lower thermal conductivity, allowing for thinner walls on complex piping runs. We also research sensor-integrated insulation skins to detect liquid ingress early and help prevent Corrosion Under Insulation (CUI).
For international buyers and engineering contractors, Kingflex offers streamlined logistics, compliance documents, and customized sizes. We align with global standards (ASTM, BS, EN, ISO). Each shipment includes mill certificates, tracking barcodes, and detailed chemical testing profiles. This makes it easy for sourcing managers to document regulatory compliance at the building site.
Our ISO-certified manufacturing base features high-output automated extrusion lines and continuous curing ovens to ensure uniform cell distribution.
Designed for multi-scenario operations, our insulation materials are engineered for complex heating, ventilation, and industrial chemical installations.
