Kingflex
Engineered for cold preservation, industrial HVAC, cryogenic isolation, and high-ambient humidity condensation mitigation.
For over four decades, Kingflex has stood as a pioneer in technical foam extrusion, supplying standard-setting systems worldwide.
Kingflex Insulation Co., Ltd. is a professional manufacturing and trading combo for high-end thermal insulation products. Our advanced research, development, and state-of-the-art production departments are situated in Dacheng, China—the recognized global capital of green-building materials. As an energy-saving, environmentally conscious enterprise, we concentrate on the complete lifecycle of thermal management: R&D, industrial-scale production, global sales, installation guidance, and dedicated post-sale engineering support.
At our core, we take energy conservation and consumption reduction as fundamental design philosophies. We provide integrated solutions for thermal insulation, cold preservation, cryogenic piping, and acoustic damping to lead the progression of building services and heavy industry worldwide.
Kingflex was established by the Jinwei Group (also historically referred to as the Kingway Group), which commands over 40 years of manufacturing history. Established in 1979, Jinwei Group was the first manufacturer of technical thermal insulation materials north of the Yangtze River. This rich manufacturing heritage underpins our strict quality systems and product reliability, ensuring that every batch of NBR/PVC foam produced meets rigorous commercial building and heavy industrial requirements.
Backed by structural supply stability, dedicated human assets, and verified global deployment records.
Our tight-knit, talented team shares a vision of delivering first-class service. Kingflex supports global procurement via 8 professional engineers in our dedicated R&D Department, 6 professional international sales engineers, and a skilled manufacturing force of 230 workers. This team structure enables rapid OEM design, precise ASTM/BS fire-safety testing compliance, and seamless customs facilitation.
Our consistent manufacturing compliance has earned us the status of a designated thermal insulation production enterprise for the Ministry of Energy, the Ministry of Electric Power, and the Ministry of Chemical Industry in China. This elite endorsement validates our ability to maintain uninterrupted material supply lines for critical global infrastructure, chemical processing plants, and marine logistics centers.
How Kingflex addresses the specific ambient heat and humidity challenges of Southeast Asian industrial projects.
In Malaysia, ambient humidity regularly exceeds 85%, and high temperatures trigger condensation on chilled water pipes and ductwork. Closed-cell NBR/PVC elastomeric foam features a high water vapor diffusion resistance factor (μ ≥ 10,000), eliminating the risk of moisture ingress, mold, and Under-Insulation Corrosion (CUI).
Compliance with Malaysia's Uniform Building By-Laws (UBBL) is critical. Kingflex products are engineered and tested to BS 476 Part 6 (Fire Propagation) and Part 7 (Surface Spread of Flame) to achieve Class 0 status, alongside UL94, CE, and ASTM certifications, ensuring approval by local fire authorities (Bomba).
We supply district cooling plants (DCS) and commercial complexes across Kuala Lumpur, Penang, and Johor Bahru. Kingflex NBR foam maintains low thermal conductivity (λ ≤ 0.034 W/m·K at 0°C) over operational lifespans exceeding 15 years, reducing system energy loss and operational costs.

Why global enterprises and developers choose Kingflex as their strategic manufacturing partner.
Procuring commercial insulation materials for large-scale developments in Malaysia demands a supplier capable of scaling production without compromising quality. Operating from the green building materials hub in Dacheng, China, Kingflex runs 5 fully automated production lines.
With an annual capacity of 600,000 cubic meters, our facilities are equipped with automated mixing, continuous extrusion, and computerized curing ovens. This layout delivers several distinct advantages:
Advancing beyond basic HVAC to serve cryogenic, chemical process, and extreme low-temperature pipelines.
Modern petrochemical processing, LNG terminal operations, and low-temperature chemical logistics operate at temperatures down to -200°C. Traditional insulation materials are prone to thermal contraction cracks, leading to moisture ingress and ice formation.
Kingflex has addressed this by developing a specialized range of elastomeric cryogenic rubber foam insulation systems. Formulated with alkadiene polymers, this technology maintains flexibility at sub-zero temperatures, absorbs mechanical vibrations, and resists structural cracking.
As mechanical designs evolve, we continuously update our chemical formulations to improve performance:
Low smoke, non-corrosive formulations for cleanrooms.
No airborne particulates; ideal for medical & food processing plants.
Consistent micro-cellular structure minimizes heat transfer.
Every batch of Kingflex insulation is traceably manufactured, tested, and certified to meet international criteria.
