There are many advantages of using PET polyester fiber as the dust filter element. The current popular fiber material made of PET dust filter element has many advantages over previous materials:
1. It has good mechanical properties, stretchability and folding resistance are about 4 times that of other materials
2. It has good resistance to high temperature and low temperature. It can work at a high temperature of 150 degrees at the highest, and can work at a low temperature of -70 degrees at the lowest, with little impact on its performance.
3. It has high resistance to water and steam, and can block the penetration of oil and other organic substances.
PET dust filter is a kind of high-end fiber molecular material that is more practical recently. PET can be divided into fiber-grade polyester molecules and non-fiber-grade polyester molecules:
1. Fiber-grade polyester is the main material for making short polyester and long polyester, and it is also the main component of polyester fiber products.
2. Non-fiber grade polyester is the main material for manufacturing bottles and some films, mostly used in food packaging, electronics, construction and automotive industries. Among them, the fiber molecular materials of the dust filter are most used in the packaging industry.
According to the above information, the performance of polyester fiber material is higher than that of polypropylene material, and the price is relatively higher. It is not ruled out that some manufacturers use polypropylene instead of polyester material, and the dust filter element uses polyester fiber material, which is stiff and resistant. With high breakage, polypropylene material is mainly used to filter liquid impurities.
