Lanxess Bond‑Laminates Launches Recycled Polycarbonate Composites for Lightweight, Flame‑Retardant Electronics

Lanxess subsidiary Bond‑Laminates is advancing its Tepex line of continuous‑fiber‑reinforced thermoplastic composites, with 50 % of the matrix derived from recycled polycarbonate extracted from reusable water bottles. The new semi‑finished products target high‑performance housings for laptops, smartphones, tablets, e‑books and cellphones.

According to the company, these composites provide a robust, lightweight and easily processed alternative to traditional magnesium die‑casting. The IT and communications sector—accounting for roughly a third of global polycarbonate consumption—has long been a primary customer of the material.

The range builds on Tepex dynalite, already used in mass production of high‑strength structural components. The first variant, now in series production, features a glass‑fiber core with carbon continuous‑fiber top layers. A second variant, slated for laptop covers, employs a recycled‑polycarbonate matrix and a randomly oriented carbon‑fiber recyclate core.

Both developments exhibit exceptional mechanical performance. Thanks to halogen‑free flame protection, each material achieves UL 94 V‑0 certification at a wall thickness of 0.4 mm.

The recycled polycarbonate originates from high‑purity, high‑transparency bottles approved for food contact, ensuring a safe and sustainable feedstock.

Beyond electronics, Bond‑Laminates envisions these composites in decorative structural components for sporting goods and automotive parts. The company has already received inquiries from the sporting goods sector seeking recycled solutions.

Bond‑Laminates continues to expand its sustainable portfolio, focusing on incorporating post‑industrial and post‑consumer waste into Tepex thermoplastic matrices.
