High stiffness Makrolon® for lightweight, durable, low-carbon laptops and beyond

The evolution of laptops: thinner, stronger, and more sustainable

Amid the trends of remote work and digital learning, consumers increasingly prioritize lightweight, durable, and stylish laptops that offer seamless mobility and meet contemporary design tastes. Meanwhile, driven by a global push for sustainability, producers are embracing more sustainable materials and efficient energy practices, catalyzing a widespread move towards more responsible consumption behaviors and achieving low carbon footprint.

High stiffness properties make thin-wall design possible

High Stiffness Makrolon® enables the design of thin-walled structures while maintaining exceptional strength, ensuring robust structural integrity under external pressures.

Drop Ball Impact Assessment: Emulating common mishaps in day-to-day activities, this trial gauges the material's ability to resist shocks. High Stiffness Makrolon® can endure the force of a half-kilogram steel ball dropping from a height of one meter without structural damage. The outcome exhibits negligible distortion and commendable resistance to impact.

Weld Line Durability Evaluation: Weld lines caused during injection molding process can weaken the products’ mechanical properties. According to our internal three-point flexural testing, which follows ISO 178 standard, High Stiffness Makrolon® showcases weld line strength roughly 40% higher than conventional reinforced alternatives. Consequently, it demonstrates first-rate endurance and dependability in areas subject to heightened tension.

Pogo Load Resistance Analysis: Mimicking real-world pressure conditions like sudden falls or compressive forces, this assessment quantifies material deflection under weights. According to our internal testing, when under a ten-kilogram imposition, High Stiffness Makrolon® exhibits approximately half the deformation seen in standard reinforced materials. This superior performance stems from our pioneering research, extensive expertise, and proprietary formulas which ensure the outer layer effectively safeguards inner components during collisions or compression, maintaining maximum protection efficacy.

Good flow and smooth appearance for outstanding design

A laptop's aesthetics is deeply intertwined with the surface properties of its constituent materials. Uneven or rough surfaces detract from tactile satisfaction and visual elegance, impacting user perception and device desirability. Beyond providing exceptional robustness, High Stiffness Makrolon® plays a pivotal role in crafting a refined housing cover for laptops, significantly elevating usability and visual charm. 

In today's industry landscape, laptop design is characterized by high attention to detail—incorporating complex microstructures such as densely packed cooling grilles and high-precision screw holes. This complexity challenges manufacturing techniques in which the flow dynamics of molten materials dictate the fidelity of mold replication and subsequently influence the quality of finished products. 

When assessed through our internal spiral flow performance test, High Stiffness Makrolon® outperforms peers by a remarkable 30% margin in terms of flow distance. This translates into enhanced manufacturing efficiency, advanced craftsmanship, and an elevated user experience.

Under-water production: reducing dust and enhancing efficiency

In the molding production process, granules can generate dust that is harmful to the environment and well-being of staff. During the granule production process, traditional pelletizing process will generate dust that is harmful to the plant environment and well-being of staff. With our unique underwater pelletizing method, dust and residue which typically caused by strand-cutting method, are largely reduced, creating a safer workspace, enhancing material production yield, and achieving better economic outcomes.

CE solutions: a win-win for performance and low carbon

With the low-carbon notion permeating through the consumer electronics arena, material innovation currently aims to deliver top-tier performance while simultaneously demonstrating environmental mindfulness. Leveraging our unique expertise in formulation innovation and stringent raw material management, High Stiffness Makrolon®  post-consumer mechanically-recycled (PCR) polycarbonate portfolio delivers high-performance attributes comparable to virgin materials, while reducing waste and CO₂ emissions to meet Electronic Product Environmental Assessment Tool (EPEAT) standards*.

*Note: EPEAT® is the world’s premier ecolabel for electronics.
