Homopolymeric Acrylic (PAN) Needle Felts Homopolymeric Acrylic (PAN) Needle Felts

Using the highest quality fiber materials and world-class needling techniques and equipment, HL Filter manufactures a wide range of Acrylic (PAN) needle felts with high dust-holding capacity and good air permeability. The advantage of this fiber compared to copolymeric PAN fiber is its higher temperature resistance, improved chemical resistance and higher strength. It is used mainly where polyester cannot be used owing to high moisture conditions.

Bulk Roll Goods: weight, thickness, density, roll width, and roll length are customized at your request.

A type of acrylic, functions at higher temperatures

Good resistance to most mineral and organic acids.

Acrylic resistance to alkalis is inferior to most fibers except natural protein fibers such as silk and wool.

Acrylic has good resistance to most oxidizing agents and is superior to polyamides and protein fibers in this respect.

Excellent resistance to most common organic solvents.

High resistance to hydrolysis and good temperature resistance.

Not recommend for high concentration of strong alkalis at high temperatures.

Acrylic is more costly than polyester and polypropylene.

Continuous operating temperature 260℉ (127°C)
