The good market prospect and wide use of PPS dust bag material originate from its excellent quality and performance.

1. The thermal stability of PPS filter material is very excellent, and the thermal stability of short-term heat resistance and long-term continuous use are better than all current engineering plastics.

2. Chemical corrosion resistance. The chemical corrosion resistance of PPS is second only to the so-called "plastic" polytetrafluoroethylene (PTFE). Below 200 ℃, almost no solvent can dissolve PPS.

3. Physical and mechanical properties, the melt viscosity of PPS resin is very low, the fluidity is good, and it is particularly easy to wet and contact with glass fiber, so the filler is easy, and the glass fiber or glass fiber-inorganic filler reinforced injection molding grade pellets prepared with it , has strong tensile strength, impact resistance, bending resistance and ductility.

4. Dimensional stability, PPS dust bag injection molding products have good creep resistance, low coefficient of linear expansion and excellent dimensional stability.

5. Adhesion performance: PPS has very high bonding strength to aluminum, stainless steel, glass, etc., and the bonding strength to glass is even higher than the cohesive force of glass. Because PPS has good adhesive properties and corrosion resistance, it is very suitable for lining of chemical equipment. In addition, the chemical structure of PPS itself makes it have good flame retardant properties without adding flame retardants. PPS dust filter bag has very low dielectric constant, inductivity and dielectric loss factors, and has excellent insulation and dielectric properties in high temperature, high humidity and other environments.
