As we all know, it is difficult for pure fiber fabrics to meet the waterproof and liquid barrier properties required by standards. Therefore, the fabric must be post-finished and filmed to improve its particle barrier performance.
PTFE medical protective filter material is a light, thin, strong and durable material and a high-performance polymer.
Protective clothing is widely used in the medical industry. There are general protection and three-level protection, with the highest being three-level protection.
A mask or full-face respiratory protector should be worn during use.
Protective clothing must have the ability to prevent the penetration of micro-particles, and the filtration efficiency of non-oily particles at key parts and seams of the protective clothing should not be less than 70%.
This technical indicator is to prevent the intrusion of virus-carrying particles (such as spit, etc.). In addition, sealing strips must be attached to the seams of protective clothing to cover pinholes left during sewing of clothing.
The surface of ptfe medical protective filter material is composed of 100~200 nanofibers staggered into holes. After the fiber diameter is reduced to the nanometer level, the surface area increases, the pore size becomes smaller, and the pore volume increases, which can effectively block PM2 .5.
It also has a fibrillar microporous structure with a porosity of more than 88%. There are 1.4 billion micropores per square centimeter, with a pore size range of 0.1μm-0.5μm. This film is coated on various surfaces using a special process. On fabrics and substrates, it can become a new type of filter material.
Suzhou New Material Technology Co., Ltd. is a PTFE composite material manufacturer specializing in the research, development and production of PTFE medical protective filter materials. After years of painstaking research and development, the company not only has strong R&D strength and perfect State-of-the-art testing methods and domestically advanced experimental equipment have attracted a large number of outstanding technical talents.
