SHF2 offshore & marine compounds

Application-led compound development

SHF2 is a crosslinked halogen-free sheathing material category within IEC 60092-360. Development requires a balance of mechanical integrity, thermal behaviour and the environmental exposures specified for the installation. We help define the formulation and process strategy around shipboard or offshore power, control and instrumentation cable requirements.

Technical focus areas

• Crosslinkable polymer systems and flame-retardant formulation balance
• Mechanical properties before and after ageing, with cure evaluation
• Oil, weathering and low-temperature requirements as specified
• Enhanced oil and drilling-fluid resistance assessed as additional requirements
• Material classification and finished-cable qualification treated separately

From formulation brief to validation plan

Begin with the intended cable layer, construction and operating environment. Define the target properties and relevant test methods before comparing formulations. Review compound behaviour under representative extrusion and, where applicable, crosslinking conditions.

Material screening, production trials and finished-cable qualification provide complementary evidence. The applicable specification and acceptance criteria should be agreed for the specific project.

Enhanced oil and drilling-fluid resistance should be specified and assessed separately from the base SHF2 category.
