Specialty Polymers PEEK LCF Material for Robotics Applications

About PEEK-LCF Materials

Compared to other engineering plastics, PEEK offers more comprehensive performance. When measured against major engineering plastics and high-performance plastics, PEEK stands out with superior overall properties. It not only surpasses most high-performance plastics in terms of rigidity but also maintains excellent toughness. In addition, it demonstrates outstanding performance in heat resistance, wear resistance, and corrosion resistance.

Compared to commonly used metal materials, PEEK delivers even better performance, making it the ideal choice for "replacing metal with plastic." From a materials standpoint, PEEK outperforms conventional metals in terms of specific strength, dielectric constant, and chemical resistance. Notably, its specific strength is approximately eight times that of aluminum alloy, meaning PEEK can significantly reduce material weight while still meeting strength requirements—making it an excellent solution for lightweight design.

FAQ

Why are your pellets so long? 

What’s the difference between them and short fibers

We use long fiber composite materials because long fibers provide better mechanical properties compared to short fibers. Long fibers form a stronger structure within the material, offering higher tensile strength, impact resistance, and fatigue resistance. This makes long fiber composites perform better in applications that endure high loads, stress, and temperature changes. On the other hand, short fiber composites have shorter particles, which are suitable for general applications but do not achieve the same level of performance as long fiber composites, especially in high-performance scenarios.

Are there any special process requirements of long carbon fiber injection molding products?

We must consider the requirements of long carbon fiber for the injection molding machine screw nozzle, mold structure and injection molding process. Long carbon fiber is a relatively high cost material, and need to evaluate the cost performance problem in the selection process.
