Short-cut Acrylic Fiber
for Specialty Papers and Nonwovens
- Superior to polyester, polypropylene and cotton in rapid liquid transport capability.
- Outstanding resistance to water, chemicals, heat, micro-organisms and ultraviolet light.
- Lower specific gravity provides higher coverage per pound.
- Applications Include:
- Water filtration media
- Industrial wipes
- Household absorbent wipes
- Dry wipes
- Cosmetic scrub pads
- Battery seperators
- Good dispersion for wet-laid papers. Special water dispersible finishes available.
