Carbon Fiber Compounds are formulated to be lighter, stiffer, and stronger than traditional glass-filled compounds, allowing for more design freedom and flexibility.

Carbon Fiber Compounds offer a lightweight alternative to metal and Glass Fiber Compounds without sacrificing strength or performance, providing:

  • Strength
  • Modulus
  • Lightweighting
  • Ultra Performance
  • Metal Replacement

Because they resist the forces of bending and strain better than their Glass Fiber counterparts, Carbon Fiber Compounds help preserve and protect the performance integrity of your application over time. This means that your plastic applications will perform better and last longer.

Carbon Fiber Compounds have lower Specific Gravity than Glass Fiber Compounds, providing super strength at lighter weights. This makes Carbon Fiber Compounds an ideal choice for applications that benefit from lighter weight parts, such as automobiles, sporting goods, and automation systems like robotics and drones.
