The H13 grade high-efficiency filter material is made of polytetrafluoroethylene as the main raw material and adopts a wet molding process. It has the characteristics of uniform fiber distribution, large dust holding capacity, low resistance, and high strength. It is an ideal air filter material. .
The technical indicators of filter paper can be mainly divided into two aspects. One is the filtration characteristics of the filter paper, and the other is the physical characteristics.
Filtration characteristics include air permeability, air resistance, maximum pore size, and average pore size.
Physical properties include basis weight, thickness, stiffness, corrugation depth, bursting strength, resin content, etc.
The H13 grade high-efficiency filter material is prepared using a unique biaxial stretching technology, which can ensure complete retention of bacteria and other impurities while having a large flux.
The material has high and low temperature resistance (-200℃-260℃). It will not age, split or discolor after long-term use. It has strong weather resistance, strong acid and alkali resistance, wide chemical applicability, and can be used for gases. When filtering, it can achieve 100% retention of various phages, bacteria and particles above 0.02um.
? is a manufacturer specializing in R&D, production and sales.
It is also a provider specializing in technology development, transfer, consulting, and services in the field of new materials; R&D, production, sales, and customization; and high-efficiency separation and filtration material design solutions.
