Filter Foam

Filter foam is an advanced open-cell, ether-based polyurethane material designed to provide effective filtration while maintaining high airflow capacity. It exhibits a robust and flexible structure that enables high particle retention rates across a range of environments. Distinguished by its resilience and durability, filter foam is suitable for a wide variety of applications, from household appliances to industrial machinery, delivering an expected service life of 5 to 10 years. This dark charcoal-colored foam is engineered for optimal filtration and airflow balance, ensuring efficiency in capturing dust, allergens, and other airborne particles.

Note: We can custom-cut the foam to size for any of your projects!

Special Properties

Porous Structure - Filter foam is a net-like, open-cell foam characterized by a lineal skeleton structure. This design provides a consistent 97% void space, optimizing permeability and allowing for superior air and fluid passage.
High Durability - With a strong yet flexible composition, the foam maintains its integrity over prolonged use, even under challenging conditions, without compromising filtration quality.
Enhanced Filtration Efficiency - The foam is engineered for high dust-collecting rates, capturing a substantial volume of particulate matter while still supporting robust airflow.
Color and Aesthetic Appeal - Its deep charcoal hue makes it suitable for exposed applications, such as speaker covers, where both functionality and aesthetics are critical.

Applications

Filter foam's versatility stems from its highly porous and resilient structure, making it ideal across various sectors.

Air Filtration

Specific Uses: Central heating and air conditioning systems, small engines, air compressors, blowers, masks, vacuums, automotive air purifiers, HVAC systems in schools and motels

Benefits: High particulate retention with maintained airflow, improving indoor air quality and operational efficiency

Coalescence Separation

Specific Uses: Water separation from gasoline, full chlorinated solvents, and jet fuel

Benefits: Efficient phase separation due to the foam's high porosity, preventing contamination in sensitive applications

Noise Suppression

Specific Uses: Microwave hoods, aircraft, industrial vacuums, and high-intensity sound systems

Benefits: Sound dampening properties due to open-cell structure, reducing noise pollution and enhancing user comfort

Miscellaneous

Specific Uses: Cosmetic puffs, floor scrub pads, hydraulic line filters, lint-free wipes, pre-filters for liquid filters, paintbrush applicators, blackboard erasers

Benefits: Multipurpose functionality with gentle, non-abrasive properties suitable for delicate applications
