Properties and stability of polytetrafluoroethylene
1. Stable at room temperature and pressure, avoiding moisture, heat, and high temperatures without a true melting point. It slowly decomposes above 450 ℃ and directly becomes a gas. At 327 ℃, the mechanical strength suddenly disappears. Insoluble in any solvent. Apart from being able to react with Date: 2024-08-01 -
Microporous filtration membrane penetrates substances
The intercepted substances are mainly proteins, various types of □, bacteria, viruses, latex, particles, with a filtration accuracy of 10-4cm~10-7cm. Different pore sizes of ultrafiltration membranes are used to separate liquids, with a molecular cutting weight (CWCO) generally ranging from 60 to 5 Date: 2024-08-01 -
Performance of microporous filtration membrane
The performance profile of microporous filtration membranes is as follows: CA (cellulose acetate) is suitable for aqueous solutions and has low protein adsorption; Nylon (nylon) is suitable for aqueous solutions and various organic solvents, with low solubility, protein adsorption, and sterilization Date: 2024-08-01
