THE STRENGTH OF CARBON FIBER COMPOUNDS

Carbon fiber can be compounded with a wide range of resins and is an excellent choice for achieving high tensile and flexural strength. Only a small amount of carbon fiber reinforcement is needed for cost-optimized performance results.

PRESERVING STRUCTURAL INTEGRITY WITH MODULUS

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.

LIGHTWEIGHTING WITH CARBON FIBER COMPOUNDS

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.
