PTFE flat membrane is a semi-finished product made from rods and strips extruded from polytetrafluoroethylene and calendered into films. It is stretched at a temperature below the melting point and heat-set to obtain a porous product.
Our country has now formed the industrial production of PTFE flat membranes. The base fabric is woven with PTFE long fibers, and the PTFE short fibers are applied on the surface of the base fabric and processed into needle felt. Its composition is 100% PTFE; g Weight 800g/m2; temperature resistance 260℃; longitudinal breaking strength 600N/5cm; weft breaking strength 600N/5cm; filtration effect 99.9%.
If necessary, the surface of the PTFE needle felt can be covered with a PTFE film.
Compared with the current PPS and P84, PTFE has the same strength index, but its temperature resistance, corrosion resistance and hydrolysis are better than PPS and glass fiber; its long-term filtration effect is also better than PPS, P84 and glassfiber.
From an economic perspective, the current price of pure PTFE filter materials is more than three times higher than PPS, and even higher than glass fiber.
However, taking into account comprehensive indicators such as the service life of the filter material, the labor cost of replacing the filter bag, and the labor intensity of the staff, the comprehensive price indicator of using ptfe flat membrane is higher than that of the existing PPS, P84 and glass fiber filter materials. It’s not much, and it’s still acceptable to most companies.
And because my country’s labor costs are constantly increasing, the use of pure PTFE membrane filter materials is becoming more and more competitive even from an economic perspective.
It is a manufacturer of polytetrafluoroethylene microporous membranes that specializes in R&D, production and sales.
The materials of the products produced by our company are all imported raw materials, with high uniformity, stable performance and good breathability.
It also has high filtration efficiency and can meet the filtration efficiency level requirements of sub-high efficiency, high efficiency and ultra high efficiency filters.
