View SpecificationsAs the European Union intensifies its decarbonization targets under the EPBD (Energy Performance of Buildings Directive), Italy's industrial sector faces strict pressures to reduce energy waste. Our rubber foam insulation sheets are engineered to directly support target compliance for projects matching CAM (Criteri Ambientali Minimi) and regional energy saving structures.
From the industrial centers of Lombardy and Piedmont to the maritime shipyards of Liguria and Trieste, thermal efficiency demands are multifaceted. High ambient humidity combined with seasonal temperature swings creates a significant risk of condensation on chilled water pipes and HVAC networks. This moisture accumulation leads to Corrosion Under Insulation (CUI) and mold growth, which degrades structural longevity and compromises indoor air quality.
Kingflex elastomeric NBR solutions address these vulnerabilities through a closed-cell structural matrix. With a vapor diffusion resistance factor (μ-value ≥ 10,000) and exceptionally low thermal conductivity ($\lambda \le 0.034$ W/m·K at 0°C), our products prevent convective heat transfer and provide a continuous, reliable vapor barrier. This technical capability ensures long-term operational cost savings for Italian HVAC system owners, district heating infrastructure, and high-precision pharmaceutical production facilities.
Deploying thermal insulation in Italy requires compliance with European fire classifications and local building regulations. Our closed-cell rubber foam insulation sheet technology is formulated to satisfy demanding standards:

Our sheets offer continuous thermal resistance for air handling units (AHU), ductworks, and refrigeration lines. The micro-cellular NBR structure delivers high mechanical flexibility, which simplifies installations in confined service shafts and complex architectural retrofits.
For industrial processing of liquefied gases down to -200°C, Kingflex cryogenic elastomers provide micro-cracking resistance and low temperature flexibility. These systems limit structural stress on process pipelines, securing safe plant performance.
With high-density polymer composition, our soundproofing sheets isolate structural noise. Ideal for engine enclosures, HVAC plant rooms, and internal wastewater systems, reducing ambient decibels to meet strict acoustic mandates.

How Italian engineering consultants, mechanical contractors, and industrial operators integrate our rubber foam sheets into high-stakes projects.
Maritime structures operate under continuous exposure to high salt spray and atmospheric humidity. In shipyards building commercial vessels and passenger ships, standard materials can quickly degrade. Kingflex elastomeric sheets are designed for these demanding environments, providing reliable resistance against moisture absorption and salt crusting. The lightweight, flexible profile facilitates installation around complex marine piping layouts, shipboard HVAC configurations, and passenger cabin partitions, helping to control vibration noise and save space.
Food processing, dairy facilities, and winemaking cold lines require strict hygienic standards. Fibrous insulation can shed particles and harbor moisture, creating a risk for biological growth. Our fiber-free NBR closed-cell sheets eliminate this vector completely. Formulated with zero volatile organic compounds (VOCs) and designed to repel surface moisture, they withstand regular washdowns and chemical cleaning without compromising their thermal properties.
Modern high-rise commercial structures require high energy efficiency to meet LEED and BREEAM certifications. Our self-adhesive rubber foam sheets with reinforced aluminum foil facing simplify installation on large duct surfaces. This structure minimizes installation errors, ensures high bonding strength to metal ducts, and eliminates thermal bridging to keep HVAC energy consumption low.
Petrochemical refiners and gas processing infrastructure in industrial hubs demand continuous thermal performance. Fluctuating process temperatures can cause standard materials to crack. Our specialized low-temperature and cryogenic elastomeric formulations maintain their flexibility at sub-zero temperatures, providing steady thermal barrier performance to prevent downtime caused by external pipe failure.
Established under the Jinwei Group, which holds over 40 years of manufacturing history (founded in 1979 as the first thermal insulation manufacturer north of the Yangtze River), Kingflex has grown into a global leader in high-performance elastomeric insulation.
Operating in Dacheng, the green building materials hub of China, our facility focuses on energy conservation and sustainable practices. We offer a full cycle of support, from initial engineering design and chemical formulation to custom fabrication, installation assistance, and long-term technical consulting.
Today, our automated factory runs 5 high-speed automatic extrusion and foaming lines. We produce more than 600,000 cubic meters of high-density elastomeric material annually, serving critical projects in the chemical, power generation, HVAC, and aerospace sectors.
Supported by eight professional R&D engineers, our lab continually develops custom formulations for extreme environments.
Our international sales team, backed by 230 production personnel, manages complex supply chains and logistics directly to Italian hubs.
We utilize continuous raw material tracing and offline quality audits to ensure every batch meets target specification requirements.
Exploring how our processing steps control the micro-structure of our elastomeric foam products.
The manufacturing process uses computer-controlled dosing systems for raw nitrile-butadiene rubber (NBR) and polyvinyl chloride (PVC) raw polymers. Injected blowing agents activate at specific curing temperatures, generating a uniform, high-density cell matrix. By managing the thermal profile during cross-linking, we maintain a closed-cell ratio over 98%.
This closed-cell density prevents external air and moisture penetration, maintaining low thermal conductivity over the operational lifespan of the system. For exposed installations, we laminate our NBR substrate with multi-layer aluminum foils and self-adhesives to improve mechanical protection and simplify installation on-site.
