Kingflex
Engineered to mitigate condensation under extreme relative humidity. Crucial accessories for sealing and structural durability.
Expert analysis of thermal insulation performance parameters required for Southeast Asia's largest industrial economy.
Indonesia's tropical marine climate is characterized by persistently high relative humidity (averaging 70% to 90% year-round) and high ambient temperatures. Under these conditions, the dew point is exceptionally high. For air conditioning systems, chilled water lines, and clean room facilities in hubs like Jakarta, Surabaya, and Batam, condensation occurs almost instantly on any surface lacking adequate thermal insulation. Standard open-cell insulation systems easily saturate with moisture, leading to systemic failure, thermal bridges, and severe under-insulation corrosion (Corrosion Under Insulation - CUI).
Using Kingflex elastomeric closed-cell rubber foam insulation addresses this directly. The micro-cellular NBR/PVC structure features a high resistance factor to moisture diffusion (μ ≥ 10,000), functioning as an integrated vapor barrier. Consequently, the thermal conductivity (λ) remains stable at ≤ 0.034 W/(m·k) at 0°C over decades of continuous operation.
The applications for high-grade rubber foam insulation accessories span multiple sectors across the archipelago:
Advanced elastomeric configurations engineered for sub-zero liquid gas transport and acoustic absorption.
Leveraging high production capacity, advanced quality control, and optimized logistics for Indonesian buyers.
Kingflex Insulation Co., Ltd. is an established manufacturing and trading combo. The research, development, and primary production plants are located in Dacheng, China—a region known for green building material manufacturing. In operation, Kingflex integrates environmental stewardship with cost management to provide insulation solutions spanning research, production, shipping logistics, and installation guidance.
Our facility runs 5 advanced automatic assembly lines, generating an annual capacity exceeding 600,000 cubic meters. This scale allows us to fulfill large-scale infrastructure orders for ports, high-rises, and industrial zones across Indonesia. Kingflex is designated as an approved manufacturer by major energy, electric power, and chemical industry departments globally, shipping products to over 66 countries.
Established by the Jinwei Group, which holds a heritage of over 40 years since 1979, Kingflex stands as one of the pioneers of thermal insulation production in northern China. The team consists of 8 dedicated R&D engineers, 6 international sales specialists, and over 230 technicians on the factory floor, ensuring each batch meets rigorous standards.
| Insulation Material | Thermal Conductivity (λ) | Moisture Diffusion (μ) | Fire Classification | Ideal Application in Indonesia |
|---|---|---|---|---|
| Kingflex Rubber Foam | ≤ 0.034 W/(m·k) | ≥ 10,000 | Class 0 / Class 1 (BS 476) | Humid HVAC ducts, chilled water lines, acoustics |
| Glasswool / Fibreglass | ≥ 0.038 W/(m·k) | < 5 | Non-combustible | Dry acoustic walls (requires separate vapor barrier) |
| Rockwool / Stone wool | ≥ 0.040 W/(m·k) | < 5 | Non-combustible | High-temperature industrial ovens and boilers |
Understanding cost structures, customs duties (Form E), and shipping routes from China to Indonesian Ports.
Under the ASEAN-China Free Trade Area (ACFTA), importers can utilize Form E to secure preferential import tariffs, significantly reducing total landed costs at Indonesian customs.
Since rubber foam insulation is low density and high volume, we use expert vacuum packing for rolls and nested piping to maximize container fill rates, reducing freight costs per cubic meter.
Our pricelists are indexed to raw NBR monomer and PVC stabilizer markets, allowing us to offer real-time bulk quotes and forward contract pricing options for long-term project stability.
For shipments destined for major ports like Tanjung Priok (Jakarta), Tanjung Perak (Surabaya), or Belawan (Medan), our logistics department coordinates all export documentation. By working directly with Kingflex, you bypass intermediary distributors, securing raw factory rates, custom manufacturing tolerances, and priority production scheduling.

Technical answers to common questions about NBR/PVC elastomeric rubber foam insulation products.
It is primarily used for HVAC duct thermal insulation, chilled water lines, refrigeration pipework, solar thermal loops, and acoustic attenuation inside machine rooms and ventilation shafts to prevent condensation and minimize energy losses.
Yes. Kingflex rubber foam contains flame-retardant additives. It is certified to international fire protection standards, including BS 476 (Class 0 and Class 1) and UL94 V-0, ensuring compliance with local Indonesian building codes (SNI).
Rubber foam has a closed-cell structure with an integrated vapor barrier, making it highly resistant to moisture ingress. This is crucial for cold insulation and humid tropical climates. Rockwool is an open fibrous mineral wool suited for high-temperature applications up to 1000°C, but requires a separate protective barrier against moisture.
Yes, we provide full OEM and ODM services. We can adjust insulation dimensions, internal pipe diameters, sheet thicknesses, backing adhesives, and outer protective skins (like aluminum foil or fiberglass facing) to match specific project plans.
Kingflex products hold certifications from BS 476, CE, REACH, RoHS, UL94, and ASTM. This ensures compliance with modern regulatory and environmental standards globally.
Yes. Every production batch of Kingflex elastomeric foam sheets and tubes is labeled with batch codes, detailing raw material input lots, curing conditions, and QA inspection logs for full accountability.
We manufacture sheet rolls in thicknesses ranging from 6mm to 50mm, catering to both low-temperature cryogenic pipelines and thicker building ventilation ducts.
When installed according to specifications, Kingflex rubber foam insulation remains functional for 10 to 15 years under normal operational and ambient conditions.
