PTFE shovels have several significant advantages over plastic or metal shovels, especially in chemical processing and high temperature environments. The following are the main advantages of PTFE shovels:
1. Excellent chemical inertness:
PTFE shovels: have extremely high chemical resistance, hardly react with any chemical substances, and can withstand corrosive chemicals such as strong acids, strong bases, oxidants, solvents, etc. Suitable for industries such as chemicals and pharmaceuticals that need to handle corrosive substances.
Plastic shovels: Some plastic materials may react to certain chemicals, and their chemical stability is not as good as PTFE, and their service life is shorter.
Metal shovels: Some metals (such as stainless steel) have good corrosion resistance to certain chemicals, but they may still corrode or oxidize in extreme environments such as strong acids and strong bases.
2. High temperature resistance:
PTFE shovels: can withstand temperatures up to 260°C, and will not melt or decompose at extreme temperatures, which is very suitable for high temperature processing processes.
Plastic shovels: Most plastic materials are easy to melt and deform at high temperatures, and have poor heat resistance.
Metal shovel: Metals usually have good high temperature resistance, but they will oxidize or deform at certain high temperatures, and they have strong thermal conductivity, which can easily burn your hands when used.
3. Non-stick performance:
PTFE shovel: It has very good non-stick performance, smooth surface, and almost no adhesion to any substance, especially suitable for handling sticky or easy-to-attach materials.
Plastic shovel: It does not have excellent non-stick performance, and substances may remain after use, which is inconvenient to clean.
Metal shovel: It is easy for substances to adhere to the surface, especially when it is high temperature and when handling sticky substances, it is difficult to clean.
4. Anti-pollution and high purity:
PTFE shovel: It will not release any impurities or pollutants, and is widely used in industries with high purity requirements, such as semiconductor manufacturing, pharmaceuticals, and laboratory research.
Plastic shovel: Some plastic materials may release harmful substances at high temperatures or when in contact with chemicals, and are not suitable for high-purity environments.
Metal shovel: Some metals may release trace metal ions due to corrosion or oxidation, which may contaminate the material.
5. Wear resistance and life:
PTFE shovel: Although not as hard as metal, it has good wear resistance and long service life in chemical and high temperature environments.
Plastic shovel: Easy to wear or deform, especially when dealing with high temperatures or chemicals, the service life is short.
Metal shovel: Higher hardness, good wear resistance, but the service life may not be as good as PTFE shovel in chemical corrosive environments.
6. Electrical insulation:
PTFE shovel: It has excellent electrical insulation and is very suitable for applications where electrical conductivity needs to be avoided.
Plastic shovel: Some plastics have certain electrical insulation, but the stability is not as good as PTFE in extreme environments.
Metal shovel: It has strong conductivity and is not suitable for environments that require insulation.
