With the development of science and technology, some filter materials are emerging one after another. There are many filter materials on the market now, and PTFE filter paper is one of them.
Quantitative filter paper is similar in appearance to qualitative filter paper, except that its quantitative value is 85g/m2, but its intrinsic quality requirements are much higher than qualitative filter paper. The most important thing is that after burning, the ash content left in the paper must not exceed one ten thousandth (0.01%), so that the weight of the filtered material can be accurately obtained during analysis and measurement without causing errors.
Polytetrafluoroethylene filter paperThe material can be used for a long time in the range of -200℃-250℃. In its molecular structure, the carbon atom is surrounded by four fluorine atoms. Since the covalent radius of the fluorine atom (0.064nm) is larger than the radius of the hydrogen atom (0.028nm), the fluorine atoms can be arranged to surround the carbon chain, and Because fluorine atoms repel each other, the entire macromolecular chain does not have a zigzag shape like a hydrocarbon molecular chain.
It is a high-tech enterprise focusing on the R&D, production and sales of polytetrafluoroethylene filter paper. It has a factory area of nearly 8,000 square meters and professional production equipment. , is a partner of the top 500 companies in the United States; the products we produce are all produced from imported raw materials, with finer molecular weight, cleaner quality, and better uniformity. Moreover, we have a full set of advanced production equipment and testing instruments, as well as a complete pre-sales, sales and after-sales service system.
