The prominent properties of PPS dust bag are: good heat resistance, can be used in the temperature range of 180 ~ 220 °C; corrosion resistance close to PTFE; excellent electrical properties; excellent mechanical properties;
The disadvantages of PPS dust bag are: the price is too high, in the high temperature plastic is a low price, but much higher than the general engineering plastics; poor toughness, brittleness; medium viscosity instability. Pure PPS dust bag is rarely used alone because of its brittle performance. The PPS dust bag used is mostly modified. Specifically: 40% glass fiber reinforced PPS dust bag (R-4), inorganic filled PPS dust bag (R-8), carbon fiber reinforced PPS dust bag (G-6) and so on. The development of PPS dust bags is fast, and it is expected to become the sixth largest engineering plastic.
