Pure PTFE Packing is a pure PTFE fiber yarn braided into the square cross-section and impregnated with PTFE dispersion. High cross-sectional density and structural strength.
It is designed for valves and lower shaft speed application under medial pressure in food processing, pharmaceuticals, paper mills, fiber plants where high purity and corrosion resistance is required. PTFE packing can be also treated with lubrication, it is an economic type.
Pure PTFE Packing is made of 100% pure PTFE yarns through twisting and braiding, without any external lubricants, ensuring maximum purity and flexibility. It is widely used in industries requiring high media purity.
