polyester antistatic needle punched filter cloth         Back

As we all know, normal technical dust, like chemical dust and coal dust, is often explosive or cause fire,  when the concentration touches its explosion limit and meet the static. Therefore the filter material, which is used to make bags containing these dust, must be antistatic.   

   Besides the skill in producing the common needle punched felt,  we also need to add conductive material into the raw filter cloth in order to make the product antistatic. These two types are both in our scope of  products  

  Bringing in foreign advanced technology, we developed and produced the very filter cloth , dacron antistatic needle-punched felt filter cloth, to meet the demand of all walks of life..

The antistatic needle-punched felt and filter cloth are in the peak position in our country and have been tested by some institution in authority. The following is the report:
