Material properties of PPS dust filter bags

The good market prospects and wide range of uses of dust filter bags stem from their excellent quality and performance.

1. The thermal stability of PPS filter material is very excellent.

The short-term heat resistance and long-term continuous use thermal stability of dust removal filter bags are better than all current engineering plastics.

2. Resistant to chemical corrosion.

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

3. Physical and mechanical properties.

The melt viscosity of PPS resin is very low and has good fluidity. It is particularly easy to wet and contact with glass fiber, so it is easy to fill. The glass fiber or glass fiber-inorganic filler-reinforced injection-grade pellets prepared with it have strong stretch resistance. properties, impact resistance, bending resistance and ductility.

4. Dimensional stability.

PPS dust bag dust removal accessories have good creep resistance, low linear expansion coefficient and excellent dimensional stability.

5. Adhesion performance.

PPS has very high bonding strength to aluminum, stainless steel, glass, etc. The bonding strength to glass is even higher than the cohesion of glass. Because PPS has good bonding properties and corrosion resistance, it is very suitable for lining chemical equipment. In addition, the chemical structure of PPS itself makes it have good flame retardant properties and does not require the addition of flame retardants.

PPS dust bag has very low dielectric constant, electrical inductance and dielectric loss factor, and has excellent insulation and dielectric properties in high temperature, high humidity and other environments.
