Kingflex
Engineered elastomeric foam profiles designed for maximum thermal barrier performance and acoustic mitigation across global infrastructure networks.
Modern commercial buildings, chemical processing facilities, and cryogenic terminals represent the core battleground for greenhouse gas emission reduction. Thermally inefficient pipework and ducting systems account for up to 30% of total HVAC system losses. Industrial operations demand materials that optimize thermal equilibrium while meeting strict localized green codes.
Eco Core technology steps into this regulatory and environmental niche. By utilizing an advanced elastomeric formulation, Kingflex provides systemic solutions that prevent thermal bridging, optimize HVAC efficiency, and drastically cut downstream energy usage.
A unified global footprint built upon four decades of material engineering, robust supply chains, and extensive R&D pipelines.

In-depth technical answers key to project planning, code compliance, and structural performance.
A1: It is primarily designed to prevent condensation and minimize heat transfer on HVAC ducts, refrigeration lines, hot and cold water pipes, and industrial process systems. Its closed-cell structure also provides sound absorption, reducing structure-borne noise in mechanical installations.
A2: Yes. Kingflex formulations include built-in fire retardants to meet international standards such as BS 476 (Class 0 and Class 1), ASTM E84, and UL 94. The materials are designed to be self-extinguishing when the external flame source is removed, minimizing flame propagation.
A3: Rubber foam features a flexible, closed-cell structure with a high water vapor resistance factor, making it ideal for moisture prevention in HVAC and refrigeration systems. Rock wool is a fibrous mineral insulation that excels in high-temperature industrial settings and structural fire barriers, though it requires an external vapor barrier in cooling applications to prevent moisture absorption.
A4: Yes, we provide full OEM and ODM services. This includes manufacturing custom wall thicknesses, inner diameters, prefabricated geometries, and specialty configurations such as self-adhesive backings and mechanical protective jacketing.
A5: Our products are certified under BS 476, CE, REACH, RoHS, UL 94, and ASTM. This ensures compliance with structural safety, mechanical performance, and environmental standards across international markets.
A6: Yes. We trace every stage of the manufacturing process from raw polymer sourcing to chemical mixing, extrusion, foaming, and final QA inspection, enabling reliable lot-by-lot tracking.
A7: Our automated production lines manufacture sheets and rolls in thicknesses ranging from 6mm to 50mm, allowing us to meet varying project specifications for thermal resistance and condensation prevention.
A8: When properly installed and maintained under standard operating conditions (within -40℃ to 105℃), our materials provide a service life of 10 to 15 years, retaining their physical flexibility and low thermal conductivity.
