Borealis, a leading provider of innovative solutions in the fields of polyolefins, base chemicals, and fertilizers, has announced the launch of FR6012. This new sheathing compound, which is halogen-free and flame-retardant, is specifically designed for medium to extra-high-voltage cables. The compound has been engineered to meet the stringent ST12 fire-performance standards, offering an optimal balance of safety and mechanical durability. This development is particularly beneficial for energy providers, enabling them to adhere to increasingly strict safety regulations in high-risk environments and critical infrastructure.
The development of FR6012 was a collaborative effort between Borealis, NKT Portugal (formerly known as Solidal), and other technology partners. NKT, a leading supplier of power cables and cable accessories, lent their expertise to ensure the compound meets both production and performance needs. The result is a compound that enables cable designs to meet the rigorous ST12 performance standards, including up to the Construction Products Regulation’s Euroclass B2ca s1a, d0, a1 classification. This classification signifies a very limited contribution to fire, very low smoke, no flaming droplets, and very low acidity and corrosivity of decomposition gases.
Furthermore, FR6012 aligns with the latest ST12 references in key International Electrotechnical Commission (IEC) standards—IEC 60502-2 and Amendment 1, IEC 60840 and IEC 62067. These standards define the safety and performance requirements for power cables ranging from 6 to 500 kV.
Beyond its exceptional safety and compliance performance, FR6012 also offers cost efficiency for both cable producers and asset owners. For cable producers, the compound’s excellent processability on standard jacketing lines helps to mitigate production-related asset risks.
The launch of FR6012 underscores Borealis’ enduring commitment to the energy sector and its role in facilitating energy distribution. By offering innovative material solutions that enhance safety and reliability, Borealis is supporting its customers as they undertake the network expansion necessary for electrification and decarbonization.
“Fire safety is becoming a defining performance requirement for the next generation of power networks. With FR6012, we are providing our customers with a material solution they can trust as they expand and modernize critical infrastructure. This launch is another step in how we are building for the future — delivering safer, more resilient, and more electrified energy systems,” stated Bart Verheule, Vice President Marketing, Borealis Energy.
