Boiler special filter bag material is divided into two categories: boiler special series (medium temperature, high temperature and strong high temperature resistant filter material) and polytetrafluoroethylene (PTFE) composite fiber filter material series.

I .  Special series filter material for boiler

(1) Special filter material for medium temperature boiler: gram weight: 800g/m2, fiber layer/base cloth: PPS+glass fiber/glass fiber base cloth. Thickness: 2.5mm thick. Working temperature: 160-190. Post-processing method: PTFE processing.

(2) Special filter material for high temperature boiler: gram weight 800g/m2, fiber layer/base cloth: P84+PPS+glass fiber, thickness: 2.5mm, working temperature: 190-220, post-treatment method: PTFE treatment.

(3) Special filter material for high temperature resistant boiler: gram weight: 800g/m2, fiber surface layer/base cloth, thickness 2.5mm, working temperature: 220-350, post-treatment method: PTFE post-treatment.

II. PTFE composite fiber series: (1) P84+PTFE needle-punched filter felt:
