Pure Ptfe Packing
Pure PTFE packing is a type of sealing material made from polytetrafluoroethylene (PTFE), known for its excellent chemical resistance and high-temperature stability.
Specs:
1. Material: 100% pure PTFE, which is non-toxic and chemically inert.
2. Temperature Range: Typically can withstand temperatures from -200°C to +260°C (-328°F to +500°F).
3. Chemical Resistance: Highly resistant to a wide range of chemicals, including acids, bases, and solvents.
4. Applications: Commonly used in pumps, valves, and other industrial equipment to prevent leaks and ensure a tight seal.
5. Density: Generally around 2.2 g/cm³.
6. Dimensions: Available in various sizes and shapes, including square, round, and custom configurations to fit specific applications.
7. Advantages: Low friction, excellent thermal stability, and resistance to aging and weathering.
Product Description:
It is a braided packing made of pure PTFE thin yarn fiber. It is a very plastic packing Under a minimum pressure of the stuffing box. it keeps unchanged in the long run . The low friction coefficient prevents the surface of the shaft from forming heat even in the presence of high penpheral speeds. It is suitable for high-concentrated chemical products that are strongly aggressive and oxidative. It is recommended for shafts for almost all chemicals．Stability and long service lift are achieved by low friction coefficient It has great tear strength and high thermal conductivity This self lubrication packing does not score the shaft and minimizes sleeve replacement cost. It can be used to seal alkalis, solvents, water, steam, and acids except strong oxidizing acids (aqua regia, fuming nitric acid, fuming nitric acid, fuming sulfuric acid, etc.) for centrifugal pumps, autoclaes, agitators, mixers, etc.
