Product Description

Polyester Filter Felt

Product Item: Polyester Filter Felt for Normal Working Temperature 

Product Intorduction:

  Our polyester needle punched felt has the following characters: 

  1.High tenacity and low elongation polyester yarn for scrim material, which enhances the  breaking strength 

  2.Fine fiber: makes the felt more apertures with smaller opening to improve the filtration  precise. 

  3.High quality polyester fiber: improves acid proof, alkali proof, and hydrolysis proof ability. 

  4.Smoother surface: makes the filtration efficiency similar with membrane felt. 

  5.Small running resistance: saves energy.
