AcroFiltrex - the diverse water based binders for better filtration and protection 

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.

 

Benefits of water-based binders

Difference between water and solvent-based binders

AcroFiltrex are water-based binders designed for better filtration and advanced protection. We offer a line of 3 categories of binders: AcroFiltrex CLASSIC, PURE and PLUS

AcroFiltrex CLASSIC

Provides excellent performance and highest durability with water-based binders

AcroFiltrex PURE
Eco-friendly, no formaldehyde added, and with advanced sustainability attributes
AcroFiltrex PLUS

Designed specifically for high-end filtration niches with additional functionality

AcroFiltrex CLASSIC

AcroFiltrex CLASSIC binders provide excellent water resistance, high physical strength, and exceptional stiffness. Their high performances enable filters to withstand tough conditions, even at high humidity and temperature levels, granting them the top positions. 

AcroFiltrex PURE

In an effort to increase the safety and sustainability of our products, we go an extra step to design AcroFiltrex PURE: a series of no-formaldehyde added binders with low VOC for filtration applications. These binders also have upgraded wet strength, reinforced chemical and heat durability to excel in the toughest environments.

AcroFiltrex PLUS

AcroFiltrex PLUS is your best option if you are looking to differentiate your filters in the competitive market. BASF creates binders with advanced functionalities designed to excel in niche markets. Binders with flame retardancy, formaldehyde abatement, or ultra hydrophobicity properties are now achievable with AcroFiltrex PLUS binders.

Flame Retardancy                
AcroFiltrex PLUS products provide end users a critical layer of fire protection by offering self-extinguishing capabilities. Our binders also achieve superior thermal aging resistance, by providing exceptional mechanical durability, enabling the binders to withstand high pressures (Mullen > 200kPa) even after aging at 160°C for 24 hours. 
Formaldehyde Abatement 
Some of our AcroFiltrex PLUS special formulation allows our binders to capture free formaldehyde from the surroundings, ensuring a safe and pleasant environment  
Ultra Hydrophobicity             
Selected AcroFiltrex PLUS products are extremely hydrophobic. This prevents water vapour from damaging the filter paper, thus prolonging its overall service life. Our binders offer more than 30 minutes of penetration time when dripped with 36 vol.-% ethanol/water solution, making it highly effective in delaying the absorption of moisture by cellulose fibers.

Empowering functions by Acrodur®

Acrodur® is an all-rounded crosslinking agent designed to perform in a variety of contexts. The addition of it into the AcroFiltrex products greatly improves the mechanical properties of the resultant filter. 

✓   Melamine formaldehyde completely replaced with Acrodur®

✓   Formaldehyde free: eco-friendly for the full life cycle of the filter

✓   Greatly improved wet stiffness, tensile and burst strength

✓   A completely new level of water resistance, chemical and heat durability

✓   Improved flame retardancy

Carbon footprint reduction solution

BASF’s biomass balance approach contributes to the use of renewable raw materials in its integrated production system, and can be applied to AcroFiltrex products.
