BASF is proud to introduce AcroFiltrex, a complete system of water-based binders designed for air filtration. From economical options to those with specific functionalities, AcroFiltrex has a product to fit your needs
Effective air filtration has long been an essential component for modern industries. From automotive air filters for passenger cars to industrial filters for gas turbines, filters play a key role in removing contaminants to protect engines.
Filtration media is comprised of impregnated cellulose fibers using a “wet-laid” process. Because they are innately soft and can easily be damaged through prolonged contact with water, effective air filtration relies heavily on a high-performing binder to protect the filter paper with an appropriate level of strength, stiffness and water resistance.
Setting New Standard in Filtration with AcroFiltrex CLASSIC
Excellent water resistance, high physical strength, and exceptional stiffness — key characteristics for a fine filter — are now all possible with AcroFiltrex CLASSIC. The uniquely designed dispersions are designed to offer exceptional water resistance while keeping formaldehyde emission levels low.
Acrofiltrex CLASSIC products outperform market products in many aspects. But among all, the superior hot water durability has granted its top position in the market.
Our CLASSIC binders designed to enable the filter to withstand harsh condition even at high humidity and high temperature. This means filter can be extra durable and can enjoy extended service life.
AcroFiltrex PURE Guarantees No Added Formaldehyde
Most currently available binders release formaldehyde during drying and post-curing processes to achieve their strength requirements. However, hazardous and highly carcinogenic formaldehyde will continue to be released during the full life cycle of the filter paper.
Safety & Sustainability remains BASF’s utmost priority and as such, we have specifically designed low VOC with no-formaldehyde-
added binders for air filtration applications. These binders even have upgraded wet strength, as well as reinforced chemical and heat durability to excel in the harshest environments.
Remarks: Low level of formaldehyde may be found in substrates
Gain Extra Functionalities with AcroFiltrex PLUS
Flame Retardancy
Flame-retardant AcroFiltrex PLUS products provide end users a critical layer of fire protection by offering self-extinguishing capabilities in case of an emergency.
Besides flame retardancy properties, our binders are also engineered to have superior thermal aging properties. These imbue the filter paper with exceptional mechanical durability, enabling them to withstand high pressures (Mullen > 200 kPa), even after aging at 160°C for 24 hours.
This translates into additional protection for room occupants, yourself, and your loved ones.
Ultra Hydrophobicity
Selected AcroFiltrex PLUS products are extremely hydrophobic. This prevents water vapor from damaging the filter paper, thus prolonging the overall service life of the filter. Ultra hydrophobic binders offer more than 30 minutes of penetration time with 36% alcohol, making it highly effective in delaying the absorption of moisture by cellulose fiber.
Formaldehyde Abatement
Advanced formulation allows our binders to capture free formaldehyde from the surroundings, ensuring a safe and pleasant environment.
Remarks: Data shows sample submerged in 50 ppm formaldehyde solution
Gain More Benefits with Acrodur®
While a high performing binder is the key to an excellent filter, a crosslinking agent makes a huge difference in its final properties.
Acrodur® is a water-based and formaldehyde-free crosslinking acrylate resin that boasts excellent binding properties. An addition of Acrodur® into Acrofiltrex binders brings unrivalled advantages to the filter in terms of performance and sustainability.
