A PTFE ball is a spherical component made from polytetrafluoroethylene, known for its exceptional chemical resistance, low friction, and high-temperature tolerance. Its main uses include serving as seals, valves, and bearings in industries such as chemical processing, pharmaceuticals, food and beverage, and aerospace, where durability and non-reactivity are critical.
Polytetrafluoroethylene (PTFE) fiber is utilized in the textile and apparel industry for its exceptional properties. It offers outstanding water and oil repellency, high chemical resistance, and excellent thermal stability. These characteristics make PTFE fiber ideal for producing high-performance fabrics used in waterproof and breathable outerwear, protective clothing, filtration materials, and industrial textiles, enhancing durability and functionality in demanding applications.

Soft iron ring joint gaskets are made from a relatively soft, malleable material that compresses easily to form a tight seal, making them suitable for lower pressure applications and flanges with less demanding surface finishes. Stainless steel ring joint gaskets offer higher strength, excellent corrosion resistance, and durability in high-pressure, high-temperature, and corrosive environments, but they require higher bolt loads to seat properly and demand smoother flange surfaces.
