Chemical corrosion resistance and weather resistance: Cleanroom FFU filter membranes are almost not corroded by any chemical reagents except molten alkali metals.
For example, when boiled in concentrated sulfuric acid, nitric acid, hydrochloric acid, or even aqua regia, its weight and performance remain unchanged. It is also almost insoluble in all solvents, and is only slightly soluble in all alkanes above 300°C (about 0.1g/100g ).
PTFE does not absorb moisture, is non-flammable, and is extremely stable to oxygen and ultraviolet rays, so it has excellent weather resistance.
The PTFE materials produced by the manufacturer are all imported raw materials, with a full set of advanced production equipment, an advanced clean room and an independent composite slitting workshop to ensure the production quality of PTFE membrane; it is imported from the United States Produces testing instruments to detect the quality of PTFE film, and has passed international SGS testing and certification, as well as ISI testing and certification.
