Polypropylene Absolute Precision Filter Bag The APTM series products are absolute precision polypropylene filter bags (APTM). They are composed of polypropylene film, extracted polypropylene microfibers, and other necessary materials. The composite material structure enables high removal efficiency, high dirt-holding capacity, and high oil absorption capacity. APTM filter bags are suitable for oil removal in the paint and coatings industry. APTM is also applicable to special fields such as electronics and microelectronics. APTM functions are very close to 3M's 100 and 300 series and can serve as replacements for these products.
