Brief Introduction To The Performance Of Ptfe Valve Lining Materials

The corrosion resistance of Lined Valve is recognized by many manufacturers, and its fluorine lining material is the core of corrosion resistance of this type of valve products. Faced with many PTFE-lined valves on the market, all fluorine lining materials are also different. So what are the materials that can be made into PTFE-lined valves?
There are 7 common PTFE-lined valves, namely polytetrafluoroethylene, polyperfluoroethylene, polytrifluoroethylene, polyvinylidene fluoride, polypropylene, polyolefin and polyvinyl chloride. Let's take a look at some of their related characteristics:
Polytetrafluoroethylene: stable performance, especially in terms of heat resistance, but the wear resistance and cold resistance coefficient are poor, the mechanical properties are low, and the flow performance is weak.
Polyperfluoroethylene: The advantage is high toughness, which can effectively prevent radioactive substances in the medium.
Polytrifluoroethylene: The performance is average, but its mechanical strength and hardness are still good.
Polyvinylidene fluoride: Excellent tensile and compressive properties, can effectively resist basic problems such as bending and aging, and is a tough material.
Polypropylene: One of the lighter materials, it is easier to mold in terms of rigidity and heat resistance, and the elastic coefficient is improved after molding.
Polyolefin: It is a very anti-corrosion material, suitable for making valve linings.
Polyvinyl chloride: Stable performance, easier to bond, and cost-effective.
PTFE lined valves made of suitable fluorine-lined materials often have different advantages. You can refer to the performance of the above materials in the market to choose suitable valve products.
