Explore our core certified insulation products engineered for optimal thermal control and extreme flame-spread protection.
In modern industrial design and commercial architecture, thermal insulation is no longer evaluated solely by its thermal conductivity ($k$-value). The rapid vertical expansion of urban structures and the increasing complexity of industrial process plants have positioned fire safety as an absolute priority. Class 0 Fire Rating materials represent the pinnacle of passive fire defense within building regulations, particularly under the British Standards framework (BS 476 Part 6 & 7) and relevant global equivalents.
Selecting the right insulation requires balancing fire safety, thermal performance, and moisture resistance. The table below highlights the key differences between various industrial insulation configurations:
| Material Class | Thermal Conductivity (W/m·K) | Moisture Resistance (μ) | BS 476 Fire Rating | Primary Industrial Use Case |
|---|---|---|---|---|
| Kingflex Elastomeric Rubber | ≤ 0.034 (at 0°C) | ≥ 10,000 (Closed-Cell) | Class 0 / Class 1 | HVAC, Cryogenic, Cleanrooms, Marine |
| Standard NBR/PVC Foam | 0.036 - 0.040 | ≥ 5,000 | Class 1 / Class 2 | General HVAC, Plumbing Systems |
| Rock Wool Insulation | 0.038 - 0.044 | ~ 1 (Open-Cell) | Non-combustible (Class A1) | High-Temp Process Piping, Furnaces |
As regulatory bodies globally enforce stricter ESG (Environmental, Social, and Governance) targets and net-zero strategies, the fire-rated materials market is undergoing a massive transformation:
Over four decades of dedicated engineering excellence and state-of-the-art automated manufacturing capabilities.
Located in Dacheng, China—the capital of green-building materials—Kingflex Insulation Co., Ltd. has integrated Factory 4.0 automation concepts. Our automated system synchronizes raw material compounding, continuous extrusion foaming, vulcanization curing, and automated dimensions scanning to guarantee consistency across every single production run.
5 large-scale automated continuous lines minimize physical labor intervention, reducing variances in density ($40 - 55\text{ kg/m}^3$) and cell size uniformity.
Led by 8 professional insulation material R&D engineers to optimize foam density, compression resilience (>80%), and fire performance characteristics.
Integrated ERP tracking means every single roll of sheet or pipe insulation can be traced back to its specific production line, batch number, and chemical input mix.
Kingflex materials meet strict global requirements to simplify import compliance and verify architectural safety criteria:
Different commercial and industrial settings demand localized design variables. Below are typical application fields for Kingflex elastomeric closed-cell insulation materials:
Used to prevent surface condensation on cold water piping, chilled air ducts, and hot water lines. The low thermal conductivity maintains system temperatures, optimizing chiller loads.
In cryogenic plants, liquified gas storage, and cold chain transportation systems, our specialized insulation materials provide elasticity at temperatures as low as -40°C (and specialized versions for lower ranges) to prevent thermal stress cracking and catastrophic failures.
The microbial and mold resistant nature of our NBR/PVC closed-cell structures prevents moisture accumulation, neutralizing bacterial growth vectors within air circulation lines.
