PBT provides good thermal stability and mechanical strength under elevated-temperature conditions. The standard PBT configuration is listed for operating temperatures below 100°C, while versions with stainless steel lining can support temperatures below 120°C. Final suitability should still be confirmed according to pressure, fluid composition, and actual operating conditions.

PBT offers broad chemical resistance and can be suitable for many acids, bases, oxidizing chemicals, and organic solvents. However, compatibility depends on chemical type, concentration, temperature, exposure time, seal material, and cartridge construction. The listed pH range is 1–10, but the complete process conditions should be evaluated before use.

The correct micron rating depends on the required particle retention, process cleanliness target, contaminant load, flow rate, allowable pressure drop, and downstream requirements. Fine ratings may be selected for polishing or higher-purity applications, while larger pore sizes can be used for clarification or prefiltration.

The listed positive pressure resistance is 4 bar at 23°C, while the allowable pressure decreases at higher temperatures. At 110°C, the listed pressure resistance is 0.5 bar. Because temperature can significantly affect cartridge strength, pressure and temperature should always be evaluated together when selecting the operating conditions.

Compatibility should be checked according to cartridge length, outer diameter, end-cap configuration, seal type, support structure, and housing interface. Available lengths include 10", 20", 30", and 40", with multiple end-cap options. Providing your current cartridge model, dimensions, process fluid, temperature, and operating pressure is the most reliable way to confirm interchangeability.
