PTFE bubble point membrane composite material is the core part of the filtration system. It is not only the last barrier of the filtration system, but also the most important barrier. It shoulders the important task of removing high-performance particulate matter. Let’s take a look at it below.
Membrane separation is currently one of the most widely used separation technologies in the pharmaceutical industry; its main feature is to use selective permeability membranes as a means of separation to achieve separation of material molecular sizes and separation of mixed components.
It plays an important role in key steps such as impurity removal, concentration and sterilization in the pharmaceutical process. Therefore, the integrity of membrane separation filters is the basic condition to ensure controllable drug quality; this article will briefly introduce the bubbles in integrity testing. Point testing and diffusion flow testing.
PTFE bubble point film composite material has a fibrillar microporous structure with a porosity of more than 88%. There are 1.4 billion micropores per square centimeter and the pore size range is 0.1μm-0.5μm. This film is coated on the It can be used as a new type of filter material on various fabrics and substrates. The membrane has small pore size, uniform distribution and large porosity. While maintaining air circulation, it can filter all dust particles including bacteria to achieve advanced purification and ventilation. Purpose.
PTFE film manufacturer specializes in the production of PTFE bubble point film composite materials. It has a full set of advanced production equipment and technology, and also has an advanced clean room and an independent composite slitting workshop to ensure the production quality of PTFE film; the products produced The materials are all imported raw materials, with high uniformity, stable performance, good air permeability, and the filtration efficiency can reach 99.999995%! It can basically meet the filtration efficiency grade requirements of sub-high efficiency, high efficiency and ultra high efficiency filters.
