This method
is used for various polymers, including long fiber
reinforced thermoplastics (LFRT or LFT).
LFTs use
reinforcement fibers (e.g., glass or carbon) that are
in parallel alignment and of uniform length (typically
12 mm), offering metal replacement performance.
Injection molded long fiber composites deliver
comparable performance characteristics to
metals and offer excellent strength-to-weight
ratios.

Controlled dispersion and high-quality carbon black materials enable you to achieve optimal performance for high-temperature extrusion and molding processes.
High-quality carbon black materials
Engineered with short fiber reinforcements to provide precise levels of electrical conductivity
https://www.avient.com/sites/default/files/2020-09/stat-tech-tri-fold-processing-guide.pdf
These materials combine the performance
of select engineering resins with reinforcing additives, such as carbon powder, carbon fiber, nickel-coated carbon fiber and
stainless steel fiber, for low-to-high levels of conductivity depending upon application requirements.
