It is primarily used for commercial HVAC duct wrapping, refrigerant pipe insulation, domestic hot and cold water systems, industrial process piping, and acoustic dampening. Its closed-cell structure helps prevent condensation and heat transfer in cold-water and refrigeration systems.
Yes, Kingflex insulation is formulated with flame retardants to meet BS 476 Part 6 & 7 (Class 0/Class 1) and UL 94 V-0 flame-retardant standards. It is self-extinguishing when the source of ignition is removed, helping limit flame spread along pipe runs.
Rubber foam is a flexible, closed-cell material with high moisture resistance ($\mu \ge 10,000$), making it suitable for cold systems, refrigeration, and HVAC where condensation is a concern. Rock wool is a fibrous mineral insulation that withstands higher operating temperatures, making it suitable for industrial steam systems and high-temperature fire stops.
Yes, we offer OEM services to support custom dimensions, wall thicknesses, packaging requirements, and specialized backings (such as factory-applied aluminum foils or pressure-sensitive adhesives).
Our products comply with several international standards, including BS 476, CE, REACH, RoHS, UL 94, and ASTM. Testing documentation is available upon request for project submittals.
Yes, all manufacturing batches carry tracking codes printed on the outer skin of the sheets and inner walls of the tubes. This links the product to its specific production run, raw material inputs, and quality control reports.
We manufacture continuous roll sheets in thicknesses from 6mm to 50mm. Custom single-layer thicknesses can be produced to meet specific thermal and condensation-control calculations.
Under standard operating conditions within our specified temperature limits ($-40^\circ\text{C}$ to $+105^\circ\text{C}$), the material has an expected service life of 10 to 15 years, provided joints are sealed correctly and the outer vapor barrier remains intact.
The micro-cell structure has a water vapor diffusion resistance factor ($\mu$) of $\ge 10,000$. This high resistance helps prevent moisture from entering the insulation layer, protecting against moisture accumulation and maintaining stable thermal conductivity over time.
Our logistics team handles shipping arrangements, including export documentation and port coordination, through our regional transportation network. Our proximity to major shipping hubs helps keep lead times predictable and shipping configurations optimized for ocean containers.
