PTFE Braided Packing

PTFE braided packing is a new type of sealing packing with desperse Teflon tape or tensile belt after the woven. The graphited PTFE packing has excellent chemical stability, in hot and humid environments under constant intensity, easy loading and dismantling.

Features of Braided PTFE Packing
Braided pure PTFE packing is a type of sealing material widely used in various applications due to its favorable properties. Some key features of braided PTFE impregnated packing include:

Excellent chemical resistance: PTFE (polytetrafluoroethylene) is known for its exceptional resistance to a wide range of chemicals, making braided PTFE packing suitable for sealing applications involving corrosive liquids, gases, and chemicals.

Low friction coefficient: PTFE has a very low coefficient of friction, allowing for smooth and efficient sealing without excessive wear or heat generation. This feature helps to minimize power consumption and extend the life of the packing.

High temperature stability: Braided PTFE packing can withstand high temperatures, typically up to 260®C (500®F), without deterioration or loss of sealing efficiency. This makes it suitable for demanding applications where high temperatures are involved.

High flexibility: PTFE is a highly flexible material, enabling braided PTFE packing to conform to irregular surfaces and provide effective sealing even in dynamic or reciprocating applications.

Low creep and cold flow: Braided PTFE packing shows minimal creep or cold flow, ensuring tight and reliable sealing over long periods of operation.

Easy installation and maintenance: Braided PTFE packing is typically easy to install and requires minimal maintenance, reducing downtime and costs associated with seal replacement.

Overall, braided PTFE packing offers exceptional chemical resistance, low friction, high temperature stability, flexibility, and ease of installation, making it a popular choice for a wide range of sealing applications.

Usage of Pure PTFE Braided Packing
Pure PTFE braided packing can replace and better than the traditional asbestos packing, in petroleum, chemical, chemical fertilizer, fuel, paint, chemical fiber, pharmaceutical, food and other industries widely used as the seal packing of the pump, valve.
