Glass fiber needle felt dust bag good heat resistance:
The glass fiber needle felt can withstand high temperatures below 260°C for a long period of time. This is an important characteristic that is not found in natural fibers and synthetic fibers, and it is an intrinsic factor in the increasing use of high-temperature filtration. Short-term use temperature of glass fiber needle felt up to 287 °C.
Good dimensional stability:
The glazing drill needle felt not only has good heat resistance, but also has good dimensional stability and a shrinkage rate equal to zero.
The filtration process of the glass fiber needle felt does not occur in the surface layer, but also occurs in the interior of the filter material. Therefore, the filter material of the needle felt filter has high filtration efficiency.
