MI-3901 is interlocked braided from Pure PTFE Fiber yarns and prelubed with break-in lubricant and incorporated with PTFE based dispersion. The break-in lubricant ensures extra lubrication during the complete operational life and dispersion acts as blocking agents as well as anti-frictional additives. This packing is Non Toxic and Inert in nature, hence, does not contaminate the fluid media. It has low coefficient of friction, thus, ensuring trouble free operation for a longer period. It is a soft resilient packing with high dimensional strength and low maintenance cost.
