Engineered for high thermal efficiency, extreme moisture resistance, and certified fire safety performance
Kingflex Insulation Co., Ltd. represents a top-tier professional manufacturing and trading combo for thermal insulation products. Our cutting-edge research, development, and massive manufacturing complex are situated in Dacheng, China—historically celebrated as the capital of green-building materials.
As a pioneer in energy-saving and environmental preservation, Kingflex operates under a core mission: minimizing thermal transfer and maximizing operational energy efficiency. We deliver end-to-end industrial solutions, starting from customized material formulation and R&D production, to comprehensive installation guidance and responsive post-sale assistance.
With an institutional legacy born from the prestigious Jinwei Group (established in 1979 as the first manufacturer of thermal insulation materials north of the Yangtze River), Kingflex leverages over four decades of thermal management wisdom to lead the global building materials landscape.
A technical teardown of Kingflex's superior NBR/PVC foaming process and physical dynamics
At the heart of the Kingflex elastomeric formulation is a highly controlled chemical foaming process blending premium Acrylonitrile Butadiene Rubber (NBR) and Polyvinyl Chloride (PVC). This NBR/PVC hybrid matrix is subjected to automated continuous vulcanization. This creates a matrix of independent microscopic bubbles containing dry air.
Key Performance Benefits:
Optimized system specifications across high-demand industrial sectors
Anti-condensation and high-efficiency thermal barriers designed for primary air conditioning ducts, chilled water lines, and dual-temperature water pipes. Ensures minimum energy loss in major HVAC systems.
Specifically engineered cryogenic elastomeric insulation (featuring Dolefin & Dienes synthetic compounds) capable of operating between -200°C and +105°C. Safe handling of LNG pipelines, oxygen transport, and low-temp chemical reactors.
Rugged, corrosion-resistant outer jackets combined with flexible NBR cores safeguard steam lines, refining pipelines, and storage tanks. Offers protection against both high heat loss and CUI (Corrosion Under Insulation).
Unmatched scale coupled with rigorous material testing protocols
Kingflex manages 5 large-scale, automated production lines. This setup generates an annual capacity exceeding 600,000 cubic meters. This infrastructure has earned Kingflex designated supplier status for major public institutions, including China's Ministry of Energy, Ministry of Electric Power, and Ministry of Chemical Industry.
Our dedicated R&D division is staffed by 8 expert chemical engineers. They supervise production quality alongside a team of 230 technicians. Every production run undergoes thermal conductivity, water vapor diffusion, and fire propagation testing before global dispatch.
Transparent benchmark values to help procurement teams optimize project budgets
Pricing for elastomeric rubber foam insulation sheets depends on wall thickness, fire resistance rating (e.g., Class 0 vs. Class 1), and adhesive backing type. The matrix below serves as a general commercial reference for bulk orders.
| Nominal Thickness (mm) | Target Applications | Primary Material Base | Standard Roll Dimensions | Fire Rating Compliance |
|---|---|---|---|---|
| 6mm - 9mm | Domestic HVAC ducts, refrigerant tubing, compact pipeline tracing | NBR/PVC blend | 1.2m x 30m | Class 1 (BS 476 Part 7), UL94 V-0 |
| 13mm - 19mm | Commercial air distribution systems, cold storage walls, utility pipes | NBR/PVC blend | 1.2m x 20m | Class 0 (BS 476 Part 6/7) |
| 25mm - 32mm | Chilled water systems, industrial process pipes, machine room acoustic lining | Pure NBR (Enhanced Fireproof) | 1.2m x 10m | Class 0, FM Approved, ASTM E84 |
| 40mm - 50mm | Cryogenic insulation system jackets, power plant steam mains, LNG pipelines | Fluorine-Free Cryogenic Elastomer | 1.2m x 8m | UL94 V-0, BS 476 Class 0 |
Tested and approved by third-party international testing authorities
Kingflex products are engineered to comply with strict international regulatory standards. Our materials hold certified fire-safety credentials, meeting BS 476 Part 6 & 7 (Class 0 and Class 1), as well as UL94 V-0 rating.
Our formulations strictly observe REACH and RoHS environmental directives, guaranteeing no toxic outgassing or hazardous heavy metal discharge during operational use. Each shipment is fully traceable from raw chemical compound feedstock down to individual finished rolls.
