Kingflex
High-performance elastomeric and acoustic thermal insulation materials engineered to international specifications.
Modern architectural design and dense industrial layouts require high-performance materials to control noise transmission. Sound absorbing carpet padding, historically limited to standard fiber fills, has shifted significantly toward NBR/PVC closed-cell elastomeric technology. As a leading manufacturer based in Dacheng, China, Kingflex Insulation Co., Ltd. provides customized acoustic underlayments and pipeline dampening systems that address both airborne and impact noise reduction.
Globally, procurement departments are seeking multi-functional soundproof underlayments that can simultaneously serve as acoustic dampeners, moisture barriers, and thermal insulation interfaces. Our elastomer compounds deliver exceptional sound transmission loss (STL) values, high mechanical elasticity under dynamic loads, and superior resistance to chemical deterioration.
Kingflex Insulation Co., Ltd. is a premier manufacturing and trading conglomerate specializing in high-end thermal and acoustic insulation products. Established by the Jinwei Group, which has a legacy spanning more than 40 years since its inception in 1979, Kingflex represents the pioneer of thermal insulation manufacturing in the region north of the Yangtze River.
Our centralized R&D and manufacturing facility is located in Dacheng, China—widely recognized as the national capital of green building materials. Operating with a core objective of energy conservation and pollution reduction, Kingflex integrates state-of-the-art laboratory testing, high-volume production, installation consultation, and comprehensive post-sale support to guide the evolution of commercial insulating systems.
Engineered for precise compatibility, our closed-cell elastomers display consistent structural stability across extreme temperatures.

|---|---|---|---|---|
| Black Rubber Foam Sheet Roll | Thickness: 6mm – 50mm | 40 – 55 kg/m³ | -40℃ to 105℃ | High moisture resistance factor, thermal conductivity control, uniform closed-cell foaming (>98% cell structure rate). |
| Black Rubber Foam Pipe Insulation | Thickness: 9mm – 40mm | ID: 6mm – 114mm | 40 – 55 kg/m³ | -40℃ to 105℃ | High resilience (compression recovery >80%), limits condensation and piping freeze risk, easy slip-on setup. |
| Elastomeric Cryogenic Series | Multi-layer systems & custom sheeting | 50 – 65 kg/m³ | -200℃ to 125℃ | Designed for ultra-low temperature environments, chemical processing systems, LNG piping thermal barriers. |
Our chemical expansion methods distribute consistent nitrogen cells within the polymer matrix. This reduces water absorption and maintains a stable thermal insulation factor over decades of service.
Ideal for central HVAC ducts, under-carpet layers in high-occupancy hotels, concrete slabs in mass transit systems, and acoustic enclosures in industrial complexes.
Tested to comply with BS 476 (Class 0 and Class 1 standards) and UL94 safety ratings, reducing flame spread and smoke release during critical fire scenarios.
From heavy industry plants to commercial facilities, Kingflex products provide reliable performance under demanding conditions.
Limits thermal transmission and dampens duct vibration in high-velocity air conditioning networks for commercial buildings, healthcare complexes, and schools.
Serves as a high-density, sound-absorbing underlayment beneath carpets, engineered wood, and stone tiles, preventing impact sounds from traveling through concrete structures.
Prevents outdoor corrosion under insulation (CUI), limits condensation on chilled water pipes, and withstands harsh processing plant environments.
Quality assurance at Kingflex is supported by our dedicated team of 8 professional research engineers and 230 production personnel. Our materials undergo rigorous testing protocols to confirm acoustic absorption coefficients, dynamic resilience under heavy loads, and structural integrity across their service lifespan.
We maintain full chemical and batch traceability across all 5 automatic assembly lines. Our environmental and safety compliance is verified by major international testing agencies, allowing partners to integrate Kingflex products seamlessly into projects with strict environmental standards.
Kingflex products are certified to meet international building standards, including BS 476, CE, REACH, ROHS, UL94, and ASTM. This ensures that our elastomeric systems comply with local fire safety, chemical emission, and mechanical requirements in North American, European, and Asian markets.
Through consistent quality control, we provide trace verification sheets for every production batch, ensuring consistent quality from the factory floor to the construction site.
Transparent communication, quick technical support, and reliable logistics form the basis of our long-term client relationships.
