Kingflex
Explore our primary manufacturing line of advanced flexible elastomeric foam products, engineered to satisfy high-specification mechanical, acoustic, and thermal criteria.
In modern industrial and commercial infrastructure design, the transition from traditional fibrous materials to fibre-free thermal insulation is driven by health, safety, and operational longevity.
Unlike traditional mineral wool or refractory ceramic fibers, fibre-free elastomeric materials do not shed dust, particulates, or respirable fibers. This prevents chronic respiratory exposure, fulfilling strict cleanroom regulations in healthcare, electronics, and food industries.
Fibrous mats act like sponges, absorbing moisture and accelerating CUI. Our closed-cell elastomeric structure exhibits a high water vapor transmission resistance factor (μ ≥ 10,000), blocking moisture ingress and protecting metallic pipes from corrosion.
Industrial plants require sustainable solutions. Kingflex insulation is formulated without CFCs, HFCs, or HCFCs. The long service life (10-15 years) reduces replacement cycles, decreasing the material footprint of green-building developments.
Kingflex Insulation Co., Ltd. is a professional manufacturing and trading combo for thermal insulation products. Our R&D and manufacturing divisions are strategically located in Dacheng, China, the capital of green-building materials. As an energy-saving and environmentally friendly enterprise, we integrate research, development, production, and sales into a unified structure.
Taking energy saving and consumption reduction as our core operational concept, we provide end-to-end solutions. From initial consultation, R&D trials, production coordination, installation guidance, to post-sale support, Kingflex delivers high-performance insulation systems to drive efficiency in global building and manufacturing industries.
Kingflex was established by the Jinwei Group, which boasts over 40 years of industry experience. Formed in 1979, the group was the first major manufacturer of thermal insulation materials north of the Yangtze River, laying the groundwork for our specialized research into modern non-fibrous elastomer products.
Excellence in insulation requires rigorous testing and continuous formulation refinement. Our R&D division maintains specialized testing capabilities to optimize thermal conductivity and flame retardancy.
Our workforce is characterized by a shared commitment to quality and service. Kingflex employs 8 professional engineers in our R&D Department, 6 international sales specialists, and 230 production workers. This team ensures that every production batch meets strict technical parameters.
Equipped with 5 large automatic assembly lines, our manufacturing systems achieve an annual capacity of over 600,000 cubic meters. Consequently, Kingflex has been designated as a supplier by the Ministry of Energy, the Ministry of Electric Power, and the Ministry of Chemical Industry.
