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 |
