How to distinguish the advantages and disadvantages of PTFE

Polytetrafluoroethylene is a polymer material with high chemical stability and corrosion resistance, commonly used in Bridge bearing sliding plate、 manufacturing pipes, pumps, valves, seals, etc.

equipment in the chemical, petroleum, pharmaceutical and other industries. However, there are different prices and qualities of PTFE materials in the market, the difference is mainly in the following

Several aspects.

1. Raw materials: the quality of PTFE materials depends on the quality of raw materials. In the market, there are Teflon materials with 100% imported raw materials, there are Teflon materials with 100% domestic raw materials, and there are also recycled materials and domestic materials mixed

2. Finished product color: different quality of PTFE materials, in the production process will generally add different coloring agents to form different color. High quality Teflon is generally pure white, while low quality Teflon may be yellowish or other colors.

Physical properties: The physical properties of PTFE materials mainly include density, hardness, tensile strength and so on. High-quality polytetrafluoroethylene Ethylene generally has a high density and hardness, but also has a high tensile strength and thermal stability.

4. Processing: The processing of PTFE materials will affect the quality of its finished product performance. Generally speaking, the high quality of polytetrafluoroethylene Fluoroethylene processing process is more complex, the production process requires precise control of temperature, pressure and other parameters to ensure the quality of the finished product.

To sum up, it is very important to choose high quality PTFE material to ensure the safety and performance of the equipment. The specific choice should be based on your needs to choose different PTFE materials.
