Syensqo Introduces Kalix® LD-4850

Brussels, October 16, 2025 - Syensqo, a global leader in advanced materials and specialty chemicals, announces the launch of Kalix^® LD-4850 BK000, a new low-density high-performance polyamide (HPPA) developed to address the evolving demands of the consumer electronics industry.

Kalix^® LD-4850 enables manufacturers to achieve substantial lightweighting of structural components in devices such as smartphones, AR/VR headsets, and other smart electronics. The new grade delivers over 30% weight reduction compared to conventional structural polyamides and polycarbonates, while maintaining excellent mechanical strength and premium surface aesthetics.

Engineered for applications where reduced weight is essential—such as brackets, frames, speaker housings, and AR/VR glass legs—Kalix^® LD-4850 combines high stiffness and strength with minimal warpage and low dielectric properties. This unique balance supports the development of slimmer, lighter, and more comfortable devices, in line with current hardware trends.

“With Kalix^® LD-4850, Syensqo is empowering our customers to redefine what’s possible in consumer electronics design,” said Andrew Lau, Senior Executive Vice President of Electronics & Industrial, Syensqo Specialty Polymers Global Business Unit. “By enabling significant weight reduction without sacrificing durability or visual appeal, this new HPPA grade helps manufacturers meet consumer expectations for portability and performance.”

Kalix^® LD-4850 BK000 is now commercially available worldwide and has already been adopted by leading smartphone manufacturers.
