PB10000 SERIES

Bronze-Filled PTFE

Bronze is the most popular metallic PTFE filler. Bronze is an alloy of copper and tin, so it is attacked by acids and bases. Also, bronze oxidizes during the sintering process, but this has no influence on the quality of the compound.

Bronze is used in high amounts to increase the thermal conductivity and reduce the deformation under load when bronze-filled PTFE materials are subjected to load at extreme temperatures. Bronze-filled PTFE materials have very good abrasion resistance and compressive strength. Bronze-filled PTFE materials are typically used for bearing and wear ring applications.
