Premix, LyondellBasell (LYB) and Maillefer have joined forces to deliver a technically advanced and recyclable power cable system, combining high-performance polypropylene materials, state-of-the-art compounding and leading cable manufacturing technology.

Together, the three companies offer a robust, compatible PP-based solution for MV and HV cable insulation and semiconductive screens, providing an alternative to traditional XLPE systems.

Premix contributes its expertise in conductive polymers with PRE-ELEC PP18220, a semiconductive PP compound tailored for MV and HV cable screens. It delivers excellent carbon black dispersion, stable conductivity and a flexural modulus aligned with PP insulation — ensuring compatibility and reliable performance.

“At Premix, we are proud to contribute our deep understanding of conductive materials to help build a smarter, more sustainable cable ecosystem,” says Tuomas Kiikka, business development director at Premix Group.

LYB supports the solution with Catalloy Hifax CA 7910A, a polypropylene insulation material (PP-TPO) that provides outstanding mechanical and thermal properties. Its consistency and ease of processing make it well suited for advanced cable insulation.

“This collaboration is a great example of how polymer innovation can unlock real value for manufacturers by combining performance with recyclability,” says Michael Berger, senior director of specialty polymers at LyondellBasell.

Maillefer ensures process reliability and production efficiency with multipurpose extrusion lines. Their advanced line technologies — including both horizontal and catenary CV systems — offer precise temperature control and optimized cooling to minimize shrinkback ensure uniform insulation layer and optimal cable core quality.

“Maillefer’s technology is a critical enabler of this solution. We are excited to support our customers and partners in developing competitive cable systems with processing equipment that ensures performance and reliability,” says Mikko Lahti, R&D director at Maillefer.
