The Normal Temperature Needle Punched Felt

When mentioned the working condition at the temp 90~130 degree,it would choice the material of Polyester needled felt, polypropylene needled felt, Acrylic (homopolymer material) needle punched felt. And according to the different requirement of the different working operation, the material surface treatment could be done as singeing, calendering, oil and water proof, PTFE impregnation, coating and laminating process...

INTRODUCTION:

    The Normal Temperature Needle Punched Felt 

     

    Features

     

    ● The normal temperature needle punched felt have moderate temperature- resistance.

     ● It is effective normal temperature filter material. 

     

     ● Good air premeability, great twist- resistance weariable, and effective dust-cleaning performance. 

     

     ● Widely used in the field of steel, cement, chemical industry, food processing and pharmaceutical manufacturing, etc.
