Chemical Resistance of Major Fibers in Filtration Field

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
Fiberglass 250℃ 280℃ Moderate Moderate Excellent Poort Moderate Excellent
