Filter Material Chemical Compatibility

Select a candidate material using the complete chemical and operating conditions. Then check the entire filter assembly and the performance evidence required for the process.

Six Checks Before Approving a Material

Use this table to prepare a compatibility review. It does not assign a blanket pass/fail rating to a chemical family.

Check	Information required	Why it matters
Fluid identity	Chemical name, mixture components and concentration	A broad label such as acid, solvent or alcohol does not identify the actual exposure.
Temperature	Normal, peak, start-up and cleaning temperatures	A room-temperature compatibility entry does not establish hot-process suitability.
Exposure	Continuous or batch contact, duration and cleaning cycles	Short laboratory contact and repeated industrial service are different conditions.
Complete construction	Membrane or felt, support, core, end caps, seals, adhesive and housing	The least compatible wetted component can determine the assembly limit.
Filtration function	Required retention, wettability, adsorption and extractables	Remaining physically intact is only one part of acceptable filtration performance.
Acceptance	Product-specific documentation and a defined validation method	Confirm what evidence is needed before approving production service.

Bag Media and Ring Construction

Specify polypropylene (PP), polyester (called PE in the JINLV bag catalog), nylon mesh, PTFE or metallic mesh by its full name. Review the ring, seam and housing seat alongside the medium. The bag catalog's material temperature reference does not approve every assembled configuration.

Compare filter-bag candidates

Membranes and Wetted Components

For PES, PTFE, PVDF and nylon cartridges, define liquid or gas duty, wetting behavior and the filtration objective. Include the support, end connection and seal in the review. Sterilization cycles and critical retention requirements need evidence for the actual product.

Use the membrane selector

Example: Preparing a Solvent Filtration Inquiry

Instead of asking whether a cartridge is suitable for “solvent,” provide the chemical name and blend, concentration, normal and maximum temperature, flow, retention target, exposure duration, cleaning procedure and existing seal material. Engineering can then identify a candidate construction and the remaining validation steps.

This is a specification example, not a completed customer project or a compatibility approval.

Reference and Scope

Pall's Chemical Compatibility guide explains why test conditions and actual use matter. Its product-specific ratings do not certify JINLV filters. For JINLV construction data, use the product catalogs and request confirmation for the exact assembly.
