Powering BLUETTI with Lightweight, Reliable, Low-Carbon Materials
Portable power stations have grown from emergency home backups to essential gear for off-grid lifestyles, from camping to RVs. To ensure long-term performance and safety, their enclosures must withstand heat, cold, UV, and impact. Covestro provides material solutions to protect these essential outdoor systems.
With the rise of outdoor adventures, mobile lifestyles, and off-grid living, BLUETTI aims to deliver portable power stations that excel in both rugged wilderness and domestic emergencies. The team needed materials that are lightweight yet strong, visually appealing, and low-carbon to support frequent movement without compromising safety. Covestro’s expertise in high-performance, low-carbon materials makes it the ideal partner to bring BLUETTI’s vision of a sustainable energy ecosystem to life.
Our partnership with Covestro is built on a shared vision for a greener planet. By using their bio-circular attributed raw materials, we are not only enhancing the durability and safety of our products but also reducing our environmental impact. This collaboration drives innovation and delivers reliable, stylish, sustainable power solutions.
Portable power stations often face extreme temperatures, strong UV and mechanical shocks. With BLUETTI’s LiFePO4 batteries delivering 4,000+ cycles (about 10 years of use), shell materials must remain durable and stable under long-term outdoor exposure.
As the devices generate heat during use, materials must manage thermal risks to enhance safety. They also need a low-carbon footprint to support the company’s environmental mission. And as products shift to colorful, consumer-friendly designs, materials must offer greater design freedom while ensuring reliability.

Our high-performance Bayblend® polycarbonate provides superior impact strength even in sub-zero temperatures, protecting devices during rugged transport and outdoor use. It meets UL 94 V‑0 flame retardancy standards for added operational safety.
In addition, the material also enables refined surface textures and precise color matching, supporting BLUETTI’s industry-first vibrant color options. We also provide RE version with a bio-circular attributed share to reduce carbon footprint while delivering equivalent performance to fossil-based polycarbonate.
