High Temperature Needle Punched Felt

For the industry dust collection filter bag, we would  choose the high temp needle felt fabric for the filter bag if the working temperature is above 150 ℃ , such as PPS needle punched felt. Aramid needle punched felt, PTFE neede punched felt, P84 needle punched felt. and each material felt has its own specific formance. 

  • Features
  • ● High-temperature needle punched felt are made by high temperature resisdence chemical fiber and treated with heat setting, singeing, calendaring,etc.

    The operation temperature is between 180-260℃.

    It is a kind high efficiency filter material,good twist resisdence,good wearing resisdence, great dust cleaning effective.

    Excellent resistance against acids,alkali and hydrolysis depends on material.

    Remark


    Polyphenylensulfide(PPS)

    1~14

    Applicable to the working conditions with low-oxidation gas from coal-fired boiler, waste incineration, metal smelting and chemical industries.

    Moderate resistance to oxidation, but excellent resistance to acids and alkalis.


    Polyimide (P84)

    3~13

    Applicable to corrosive gas, such as chemical, metal smelting, waste incineration industries, cement kiln and coal-fired boiler.

    Excellent resistance to high peak temperature.


    Polytertrafluoroethylene (PTFE)

    1~14


    Applicable to high-corrosive gas and high temperature, such as chemical industry, coal-fired boiler, waster incineration industry and non-ferrous metal production.

    Excellent resistance to all chemical influences.


    Glass fiber  (BQ)

    3~11

    It is extensively applicable to high temperature exhaust gas filtration of various industrial furnaces like chemical industry,steel,metallurgy,carbon black,power generation,cement,etc.,It is applicable to kinds of dusting filter bag remover as pulse deashing and hinger speed back flushing deashing etc.


    Excellent for water-proof.
