Durkflex FC-S/FC-M technology brings a new solution for industrial and
chemical processes at cryogenic temperatures. Durkflex FC-S/FC-M is a
high-performance elastomeric insulation system for cryogenics, constructed
using a special formulation for very low-temperature operation. It is
manufactured using Durkflex proprietary ACMF( Accurate control
microcellular foam ) technology. These multi-layered systems can maintain
good flexibility and a stable insulation performance for industrial cryogenic
environments at -200℃.
Durkflex FC-S/FC-M are produced using Durkflex ACMF( Accurate control microcellular foam) technology and applied with low-temperature activity formula, which ensures stable cell structure and low temperature flexibility performance. This flexibility absorbs vibrations and impact, reducing risk of crack development and propagation.
Durkflex cryogenic elastomeric insulation systems are designed with a microcellular structure and polymer formulation. The patented Durkflex foams provides a continuous barrier to vapour diffusion throughout the full thickness of the insulation, which makes the system work well without depending on a separate vapour barrier. This characteristic provides significant benefits by improving the longevity of insulation performance, and by reducing the risk of under insulation corrosion.
Compared to traditional rigid materials, easy installation is a key benefit of Durkflex cryogenic elastomeric insulation systems. The systems require no separate vapour barriers or the use of fiber-based contraction joints. Seams and joints are sealed using Durkflex cryogenic-approved adhesive. Durkflex can be easily adapted to difficult shapes and is conveniently transported on-site, which makes it possible to shorten the time needed for installation and save construction costs.
Durkflex cryogenic elastomeric insulation systems provide significant thermal performance, reduces the risk of corrosion and minimises the time needed for installation. The systems are widely used on pipelines, tanks and equipment for petrochemicals, LNG and air systems, etc.
Compared to traditional rigid materials, Durkflex cryogenic elastomeric insulation systems possess obvious advantages, such as providing pipelines protection, improving the longevity of insulation performance, ease of installation and cost saving.
