Chemical Resistance of Major Fibers in Filtration Field

TAIZHOU, China - May 29, 2019 - PRLog -- When comes to the selection of filter meshes or molded plastic filters, the first thing coming out of our mind is the micron rating, because we need filters/strainers to sift our particles from entering into fluid that we need to purify. However, sometimes, due to plastic resin's chemical properties, we cannot just take micron rating into consideration, we also have to consider chemical resistance of major fibers.

Below is the major fibers chemical resistance chart

Fiber Type  Continuous Working Temp.  Max. Working Temp.  Filtration Characteristic  Abrasion Resistance  Hydrolysis Resistance  Acid Resistance  Alkalis Resistance  Oxidation Resistance
PVC  75℃  80℃  Good  Excellent  Excellent  Excellent  Excellent  Good
PP  90℃  100℃  Good  Good  Excellent  Excellent  Excellent  Poor
PA  110℃  115℃  Moderate  Excellent  Poort  Moderate  Good  Moderate
PAN Copolymer  120℃`  130℃  Good  Good  Good  Moderate  Moderate  Good
PET  135℃  150℃  Excellent  Excellent  Poor  Moderate  Poor  Good
m-Aramide  180℃  220℃  Excellent  Excellent  Moderate  Moderate  Moderate  Good
PPS  190℃  200℃  Excellent  Good  Excellent  Excellent  Excellent  Moderate
Polyimide  240℃  280℃  Excellent  Moderate  Good  Good  Moderate  Excellent
Polyertrafluoroethylene  250℃  280℃  Moderate  Good  Excellent  Excellent  Excellent  Excellent
