Developed by Evonik, P84® Polyimide fibers are an excellent choice in demanding industrial air filtration applications where high temperatures are present, and there’s a probability of corrosion and abrasion. The fiber’s unique multi-lobal structure offers the highest surface area for filtration, compared to other fibers on the market, which are round. In addition, they stay stable in high-temperature applications with a peak operating temperature of 480°F (250 °C). The fibers are non-flammable, making them an outstanding solution for industrial air filtration.
Albarrie and Evonik have worked together to develop P84® technical textiles for over 30 years. This long relationship has helped Albarrie become a leader in the specialized processing and manufacturing of P84® nonwoven technical fabrics. Albarrie uses P84® technical textile to fabricate its custom baghouse filter bags – Tandem and Meteor – due to its increased service life, high-quality fiber, and technical support over other polyimide fibers. Albarrie manufactures P84® rolls in weights between 14 and 28 oz/yd² (475-950 g/m²) with thicknesses between 0.039 and 0.11 in. (1-3 mm).
