Durkflex FC-S/FC-M

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℃.

Features

workimg


Better thermal performance, longer lifespan

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.

Excellent resistance to water-vapour diffusion

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.

Easy installation

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.

Application Areas of Durkflex FC-S/FC-M

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.

Milestone for cryogenic insulation areas

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.

Impact resistance and contractibility

workimg

Flexibility, no in-fill pieces

Durkflex FC-S/FC-M provide low temperature flexibility performance.This flexibility absorbs vibrations and impact, reducing risk of crack development and propagation. Durkflex cryogenic elastomeric insulation systems do not require the use of fibrous materials for contraction and expansion joints, shortening 20%--40% time needed for project and saving construction cost.
workimg

Rigid material, expansion joints required

Traditional rigid insulation materials, like foam glass, PIR and PUR, are nonelastic and can be essily cracked when suffer vibration and impact. They utilise galss wool or minerral fibre at longitudinal joints as a buffer against contraction and expansion of each insulation layer. The traditional method not only needs more time for installation, but the use of open-cell fibrous material provides the potential entry of moisture, which influences insulation performance.

Performance on water-vapour resistance

workimg

Excellent resistance to water-vapour diffusion, without vapour barriers

Durkflex cryogenic elastomeric insulation systems are designed with microcellular strcture and polymer formulation. The patented Durkflex foams provide a continuous barrier to vapour diffusion throughout the full thickness of the insulation, which makes the system work well without the installation of vapour barrier. This character provides significant benefits by improving the longevity of insulation performance, and by reducing the risk of under insulation corrosion.
workimg

Traditional Rigid Materials Need Vapour Barriers

Traditional multi-layer insulation systems require a vapour barrier on each layer since they have worse self-resistance to water vapour. The application of seperate vapour barriers adds to cost and time, and any gaps or damage in these systems can undermine the performance of an entire layer of insulation.
