Kingflex
Explore our certified elastomeric sound and thermal insulation solutions designed for modern industrial applications.
Nitrile Butadiene Rubber (NBR) insulation represents the benchmark in elastomeric closed-cell foaming technology. Widely known for its exceptional resistance to moisture vapor transmission, superb thermal resistance, and flexible installation parameters, Nitrile Rubber Foam is the preferred thermal management material across structural HVAC, process piping, marine construction, and critical industrial cooling sectors.
As the construction and industrial sectors pivot towards carbon neutrality and energy performance compliance (such as LEED, BREEAM, and DGNB standards), thermal insulation is no longer just a regulatory box to tick. It is a critical engineering asset. Kingflex elastomeric closed-cell structures reduce thermal bridges, prevent condensation on cold surface pipelines, and dampen structural noise, providing an all-in-one thermal and acoustic shield.
Established under the aegis of the renowned Jinwei Group, which boasts a rich history spanning over 40 years since its inception in 1979, Kingflex Insulation Co., Ltd. has developed into the premier manufacturer of thermal insulation materials north of the Yangtze River. Based in Dacheng, China—the globally recognized capital of green building materials—our operations synthesize research and development, smart manufacturing, and global sales channels.
At Kingflex, ecological balance and conservation guide our R&D roadmap. We do not simply produce insulation; we craft comprehensive solutions encompassing consulting, system design, structural calculation, installation guidance, and technical post-sale support. Driven by the mission to supply reliable, low-conductivity building envelopes, we strive to lead the modernization of the global thermal insulation materials sector.
Innovating thermal barriers through chemistry, engineering, and continuous quality assurance.
Our research and development division consists of 8 senior materials scientists and chemical engineers dedicated to refining closed-cell rates, improving smoke-density performance, and developing cryogenic-resilient NBR foam systems.
Supported by a dedicated production team of 230 expert factory operators, our modern manufacturing site maintains high consistency, low tolerance margins, and seamless execution of high-volume contracts.
Our dedicated international customer success team manages compliance, freight optimization, and local standard alignments for EPC contractors and trade distributors across sixty-six nations.
When searching for a competitive Nitrile Rubber Insulation Price List, international procurement managers must look beyond unit costs. A direct-from-manufacturer price reflects raw polymer feedstocks, vulcanization and foaming technology, density consistency, and localized logistics. Kingflex achieves cost efficiency not by compromising material quality, but through structural, geographical, and process advantages:

How Kingflex NBR elastomeric insulation performs across diverse environmental and structural configurations.
In high-humidity commercial buildings, cold air circulating in metal ducts leads to surface condensation. Our closed-cell sheet rolls seal out moist ambient air, preventing water dripping, mold growth, and structural rot.
Chemical processing plants operate at varied temperatures. Kingflex NBR foam maintains stable thermal performance, shielding piping networks from energy loss, external moisture, and galvanic corrosion.
For machinery rooms, generator housings, and studio walls, our high-density open-cell variant is engineered to absorb mid-to-high frequency mechanical vibrations, helping facilities meet occupational health standards.
Proven durability across real-world commercial HVAC installations and industrial cooling systems.
From high-rise residential properties in tropical Southeast Asia to energy-processing plants in Northern Europe, Kingflex insulation systems provide long-term energy savings. Our solutions are designed to stand up to thermal stress and mechanical wear. By maintaining low thermal conductivity throughout their lifecycle, they reduce carbon footprints and ensure operational safety.
As standard formulations face stricter safety and environmental regulations, Kingflex continues to innovate, developing advanced solutions for the built environment.
Replacing traditional bromine-based retardants with advanced organic formulations. This maintains flame resistance while eliminating acid gas emissions during fire events.
Developing specialized flexible systems that retain their elasticity down to -196℃, specifically designed for LNG storage tank insulation and transfer pipelines.
