Engineering at the Edge: A Dual-Brand Powerhouse

Polar Technology operates through two specialist brands:

• Lentus Composites – Experts in advanced composite manufacturing, Lentus delivers components using pre-preg/autoclave moulding, filament winding, and other cutting-edge techniques. Their work spans aerospace structures, motorsport systems, and defence-grade assemblies.
• SST Technology – Focused on engineered precision fabrications and thermal management systems, SST supports high-performance applications across propulsion, energy, and aerospace platforms. Their capabilities include complex metallic structures, high-pressure pipework, and cryogenic systems.

Together, these brands offer a vertically integrated model that enables rapid prototyping, scalable production, and full lifecycle support—from concept to solution.

Recent Highlights and Strategic Momentum

Polar Technology was recently selected by ISTEC to manufacture sub-frames for the USAF Grey Wolf helicopter weapon integration mounts—a testament to its growing international footprint and defence credibility. The company also received the 2025 WIRED Trailblazer Award, recognising its leadership in innovation and sustainability.

Another standout project involves a collaboration with Ultima Forma to develop a leading-edge protection layer that enhances durability for aerospace and defence applications. This technology is already attracting interest from major aerospace organisations.
