Explore our top-tier selection of flexible closed-cell rubber insulation rolls, pipes, sheets, and cryogenic materials designed to mitigate thermal loss and eliminate moisture accumulation.
In industrial fluids, petrochemical facilities, and commercial HVAC infrastructure, maintaining steady pipeline temperatures is critical. 35mm thickness pipe insulation functions as a key barrier that optimizes thermal performance, controls condensation, and limits heat loss or gain.
From a thermodynamic perspective, heat loss occurs through conduction, convection, and radiation. Fourier's Law of Heat Conduction states that the rate of heat transfer through a material is proportional to its area and temperature gradient, and inversely proportional to its thickness:
By specifying a nominal wall thickness of 35mm, system engineers significantly increase the thermal resistance path (dx). This reduces the heat flux (Q) even in systems handling high temperature variations, such as chilled water lines at 4°C operating in hot humid ambient temperatures of 35°C, or low-pressure steam pipelines up to 105°C.
Our engineering specifications match international quality codes, offering reliable service across harsh environments.
Kingflex Insulation Co., Ltd. operates as a manufacturing and trading group specialized in high-grade thermal insulation products. Our R&D and manufacturing base is located in Dacheng, China, a recognized hub for energy-saving building materials. As an energy-conscious, environmentally focused enterprise, we focus on researching, developing, producing, and selling premium closed-cell insulation.
Established by the Jinwei Group, which brings over 40 years of industry history dating back to its founding in 1979, Kingflex is built on decades of technical expertise. Jinwei Group was the pioneer thermal insulation material manufacturer north of the Yangtze River, paving the way for our modern high-capacity operations.
Today, Kingflex operates five large, fully automated production lines yielding an annual output of over 600,000 cubic meters. Our facilities are designated as production points for key ministries, including the Ministry of Energy, the Ministry of Electric Power, and the Ministry of Chemical Industry.
Our skilled workforce includes 230 production personnel, a dedicated international trade division with 6 professional managers, and 8 senior chemical engineers in our R&D Department. This team is focused on delivering energy efficiency, anti-condensation performance, and noise mitigation products to clients worldwide.
From standard building systems to extreme industrial processes, Kingflex 35mm insulation protects critical assets across diverse sectors.
Mitigates condensation on chilled water pipes, condensate drains, and central heating loops. Used globally in hotels, malls, healthcare facilities, and offices to improve energy ratings and reduce carbon emissions.
Provides stable thermal control for chemical processing, refinery pipelines, and storage tanks. The closed-cell matrix prevents moisture ingress, reducing the risk of Corrosion Under Insulation (CUI).
Designed for ultra-low temperature environments. Prevents rapid thermal transfer and ice formation on liquid gas transfer pipelines, cold rooms, and distribution networks.
Elastomeric NBR/PVC insulation sheets and pipes are versatile materials utilized in many industries:
Our testing labs monitor quality variables to ensure consistent performance before materials leave our factory.
Procuring insulation materials for multi-million dollar HVAC, industrial, or marine projects requires balancing cost, technical compliance, and supply chain logistics.
When evaluating elastomeric rubber foam suppliers, procurement teams must look beyond unit price to verify long-term material performance. Low-quality, cheap rubber insulation often exhibits uneven density distributions and incomplete foaming structures. This degrades the closed-cell integrity over time, leading to moisture retention and an increased thermal conductivity (K-value) that compromises performance.
Kingflex helps mitigate these risks through trace-code material markings, raw material tracking, and systematic QA testing before dispatch. This ensures compliance with key international standards including ASTM, UL94, BS 476, CE, REACH, and RoHS.
Additionally, Kingflex maintains high manufacturing capacity to ensure stable supply timelines, offering direct container shipping to minimize handling damage and logistics costs for international projects.
We maintain open communication channels, keeping buyers updated from initial quotation to final shipping.
The thermal insulation sector is transforming to meet international environmental regulations and strict building safety requirements.
Modern specifications increasingly request halogen-free rubber compositions to limit toxic smoke generation in fire emergencies, protecting occupants and equipment.
Kingflex is transitioning manufacturing lines toward next-generation chemical blowing agents that offer zero Ozone Depletion Potential (ODP) and low Global Warming Potential (GWP).
We are researching integrations of flexible NBR/PVC insulation with moisture sensors, allowing operations managers to detect condensation risks inside pipe systems early.
Our insulation materials are installed across demanding international construction, oil & gas, chemical processing, and HVAC projects.
