PTFE bronze 40% 60 Shore D brown Compound
High-Strength Bronze-Filled PTFE for Load-Bearing and Wear-Resistant Sealing
PTFE Bronze 40% (60 Shore D, brown) is a reinforced PTFE compound engineered for demanding mechanical and sealing applications. The addition of 40% finely powdered bronze significantly improves the wear resistance, thermal conductivity, and compressive strength of standard PTFE, while retaining excellent chemical resistance and low friction properties.
This compound is ideal for parts exposed to high loads, dynamic motion, or elevated temperatures, and is widely used in hydraulic systems, rotating equipment, and heavy-duty seals.
