Description
Material:
Acrylic needled felt dust bag chemically known as “polyacrylonitrile”. Acrylic raw material is processed by the needle felt punch system. Afterwards it goes through special waterproof treatment. By the use these procedure, Acrylic medium temperature hydrolysis resistance needled filter felt is manufactured.
Breathable: 14 m3 / m2, min quantity
Instantaneous working temperature : 160 ℃, 140℃, normal work.
Needled felt in acrylic machine weaving as the base cloth is strengthened vertically and horizontally.
Advantages:
Dust bag with excellent chemical resistance and resistance to hydrolysis
