PTB1# is a high grade composition of virgin PTFE compounded with 40% bronze, brown color. In addition to maintaining low friction and broad temperature adaptability, the bronze filler greatly increases compressive strength, wear resistance, and heat dissipation. For precisely machined hydraulic sealing elements, it is widely used for its cost-effectiveness and balanced performance.
