Safwa Polymer

PTFE + 20% Carbon — Tube & Rod

PTFE + 20% Carbon — Tube & Rod

Form

PTFE filled with 20% carbon powder. Carbon fill delivers excellent compressive strength, good thermal conductivity, and low permeability. Less abrasive on mating surfaces than glass-filled PTFE — superior wear and friction performance, especially when combined with graphite. Suitable for high-pressure dynamic sealing and anti-static applications. Manufactured by Safwa Polymer, Badr City, Egypt.
