Explore our high-performance thermal insulation tubes, sheet rolls, and cryogenic materials certified for globally challenging conditions.
Discover the physical and engineering properties that make single-sided foil-faced insulation the gold standard for global HVAC and industrial engineering.
Laminating premium Aluminum Foil on One Side creates a composite insulation panel. The inner elastomer controls conductive heat transfer (thermal conductivity λ ≤ 0.034 W/m·K at 0°C), while the metallic exterior acts as an absolute vapor barrier (reducing moisture permeability to nearly zero) and reflects up to 97% of radiant heat.
Unprotected rubber foam is susceptible to atmospheric degradation, ozone erosion, and physical damage. Our reinforced aluminum foil cladding shields the elastomer core from UV radiation and minor surface tears, substantially extending the system service lifetime to over 10-15 years.
Aluminum acts as a barrier to flames. When combined with Class 0/Class 1 flame-retardant Kingflex rubber foam, it meets strict international safety standards (BS 476, UL94, CE). The composite material restricts smoke density and limits toxic byproducts during combustion.
Established as a premier manufacturing and trading combo for thermal insulation products, Kingflex Insulation Co., Ltd. concentrates on the research, development, production, and sales of high-end energy-saving materials. Located in Dacheng, the green-building materials capital of China, we provide specialized consultation, engineering solutions, and post-sale installation guidance globally.
Our commitment focuses on energy saving and consumption reduction. Our integrated systems provide effective solutions for buildings, industrial pipelines, and complex chemical facilities.
Kingflex was established by Jinwei Group, a group with over 40 years of industrial history. Founded in 1979, Jinwei Group was the first manufacturer of thermal insulation materials north of the Yangtze River. Decades of research have refined our processes to ensure high-performance, cost-effective manufacturing.
Today, our automated infrastructure operates five large automatic assembly lines, producing more than 600,000 cubic meters annually. This capacity has secured our position as a designated production enterprise for the Ministry of Energy, the Ministry of Electric Power, and the Ministry of Chemical Industry.
