Meltblown for Oil Sorption and Liquid Filtration
topic
Polypropylene meltblown fabrics for oil spill sorption exploit the hydrophobic and oleophilic natural surface chemistry of polypropylene that preferentially absorbs oil over water, with high-loft meltblown pads at 100 to 500 grams per square metre absorbing 10 to 20 times their weight in oil for use as spill sorbents, oil-water separation pads in industrial wastewater treatment, and marine oil spill response booms.
Role
Provides the primary material for industrial oil spill sorption and oil-water separation applications by exploiting the natural oil affinity of polypropylene meltblown that enables selective oil absorption from water surfaces and contaminated wastewater, with meltblown sorbents providing higher oil holding capacity per unit weight than woven or knitted alternatives through the high surface area-to-volume ratio of microfibre structure.
