1.PEEK-CF

ForceTracer ™ PEEK-CF is a polyetheretherketone (PEEK) material with chopped carbon fibers added. Compared with other special engineering plastics, PEEK has more significant advantages, including higher glass transition temperature (143°C) and melting point (334°C), excellent mechanical properties, good self-lubricating properties, chemical corrosion resistance, flame retardancy, and Peelability, abrasion resistance, radiation resistance, biocompatibility and thermal stability (CF reinforced PEEK can be used for a long time at 260°C. Compared with other high temperature resistant plastics such as PI, PPS, PTFE, PPO, etc., the upper limit of use temperature exceeds about 50℃).

This material is often used in high-end machinery, nuclear engineering, aviation, electronic and electrical and medical machinery and other fields.

2.PEEK-CNT

ForceTracer™ PEEK-CNT is a polyetheretherketone (PEEK) material with added carbon nanotubes that appears black. Adding CNT to PEEK maintains high impact strength and gives the material excellent antistatic capabilities. 

This material is often used inMultiple professional scenarios such as electronics and electrical, drone manufacturing , etc.
