Introduction to the Performance of PTFE Valve Lining Materials

      PTFE lined valve The corrosion resistance of this type of valve product is widely recognized by many manufacturers, and its fluorine lining material is the core of its corrosion resistance. Faced with numerous PTFE lined valves on the market, all fluorine lined materials are also different. So, what are the materials that can be used to make PTFE lined valves?
There are seven common types of PTFE lined valves, namely polytetrafluoroethylene, perfluoroethylene, polyethylene terephthalate, polyvinylidene fluoride, polypropylene, polyolefin, and polyvinyl chloride. Let's take a look at some of their related characteristics:
Polytetrafluoroethylene: It has stable performance and excellent heat resistance, but its wear and cold resistance coefficient is poor, its mechanical properties are low, and its flow performance is weak.
Polyfluoroethylene: Its advantage is high toughness, which can effectively prevent radiation substances in the medium.
Polyethylene terephthalate: Its performance is average, but its mechanical strength and hardness are still acceptable.
Polyvinylidene fluoride: a material with excellent tensile and compressive properties, which can effectively resist basic problems such as bending and aging, and is full of toughness.
Polypropylene: One of the lighter materials, it is relatively easy to shape in terms of rigidity and heat resistance, and its elasticity coefficient increases after molding.
Polyolefin: It is a very anti-corrosion material, suitable for making valve liners.
Polyvinyl chloride: stable performance, relatively easy to bond, and cost-effective.
Choosing the appropriate fluorine lined material for PTFE lined valves often has different advantages. In the market, you can refer to the performance of the above materials to choose the appropriate valve products.
