View SpecificationThe Seoul metropolitan area, as the technological and economic nucleus of South Korea, stands at the absolute center of advanced precision engineering, high-tech semiconductor fabs (located across the Gyeonggi-Incheon corridor), and maritime industrial design. As international shipping standards tighten and clean energy initiatives pivot heavily toward Liquefied Natural Gas (LNG) and Liquid Hydrogen (LH2), the demand for high-performance cryogenic insulation products has experienced exponential growth.
In ultra-low temperature applications—ranging from liquified gases at -162°C (LNG) to -196°C (Liquid Nitrogen) and down to -253°C (Liquid Hydrogen)—insulation integrity is not merely a matter of thermal efficiency. It is critical for systemic safety, boil-off gas (BOG) mitigation, and preventing structural stress from rapid thermal contraction.

Why Tier-1 EPC contractors, shipyard builders, and industrial designers specify high-efficiency flexible elastomeric systems for cryogenic applications.
In modern industrial procurement, engineers in Seoul and global partners are moving away from traditional fiberglass or rigid polyurethane blocks because of physical degradation. Rigid foams are prone to cracking under thermal contraction, and fiberglass fails rapidly if a vapor barrier is breached. By utilizing Kingflex elastomeric closed-cell rubber foam insulation systems, operators benefit from a flexible, self-resilient layer that dynamically contracts and expands in sync with steel pipelines, maintaining an unbreakable air and moisture seal.

In-depth technical answers addressing common deployment, safety, and procurement queries in the cryogenic space.
It is mainly used for HVAC ducts, air conditioning pipes, building thermal insulation, industrial pipeline cold insulation, and sound insulation. Its high flexibility makes it perfect for wrapping complex geometries in chemical plants and cleanrooms.
Yes, our rubber foam insulation is fire retardant, conforming to BS 476 Part 6 & 7 (Class 0 / Class 1) and UL94 V-0 safety standards. This ensures high flame resistance and self-extinguishing behavior in demanding commercial and industrial infrastructures.
Rubber foam is a highly flexible, closed-cell material that is inherently moisture-resistant, making it ideal for HVAC condensation control and cold/cryogenic insulation systems. In contrast, rock wool is a fibrous material with excellent high-temperature resistance and fire protection, suited for thermal insulation of steam pipes and furnaces.
Yes, we support comprehensive OEM/ODM services. We can adjust the wall thickness, internal diameter, density, and backing vapor barriers to meet the exact environmental and engineering parameters of your local project design.
Our products have successfully passed BS 476, CE, REACH, ROHS, UL94, ASTM, and other global certifications. This guarantees full compliance with municipal building codes and heavy marine engineering standards in South Korea and worldwide.
Yes, every production run is stamped with detailed manufacturing batch codes. This rigorous tracking mechanism allows us to monitor quality from raw materials through international shipping logistics to construction sites.
We can manufacture flexible sheet rolls in thicknesses ranging from 6mm up to 50mm, allowing developers to design single-layer or multi-layer configurations depending on the temperature differential requirements.
When properly installed and maintained under standard operating temperatures (-40°C to +105°C), the insulation systems have an operational life of 10 to 15 years, during which they maintain stable thermal conductivity.
For cryogenic applications down to -200°C, Kingflex utilizes a specially formulated multi-layer elastomeric system. The base layer is designed to manage thermal contraction stress, while outer layers prevent ambient moisture from reaching the cold surface, mitigating ice accumulation.
