Engineering Performance & Features of Open Cell Filter Foam
Controlled 10 PPI to 60 PPI Porosity for Targeted Dust Capture: Utilizes uniform PPI filter foam sponge structures (10 PPI to 60 PPI) to effectively intercept dust, fibers, and airborne particulates ≥15μm, preventing downstream medium and HEPA filter overloading.
High Air Permeability & Low System Resistance: Features a 97% open-cell PPI filter sponge matrix that eliminates blind pores, keeping initial resistance ≤90 Pa. This high-permeability structure maintains steady airflow while significantly lowering fan energy consumption.
Oil, Solvent & Chemical Endurance: Engineered with premium polyester and polyether resins, providing this PPI sponge filter media with excellent resistance to machine oil mists, organic solvents, and mild acids or alkalis (pH 5.0 – 8.0).
Washable & Reusable Structural Integrity: Boasts a tensile strength of 45 kPa and an elongation rate of 65%. The media tolerates repeated water washing, compressed air blowing, and chemical cleaning without structural collapse or mesh deformation.
Functional Modification Flexibility: The 3D skeletal structure serves as an optimal substrate for functional secondary coatings, including activated carbon impregnation, photocatalysts, or metallic and ceramic matrix processing.

Q1: What is the difference between 10 PPI and 60 PPI filter foam sponge, and how do I choose the right porosity?
A: PPI (Pores Per Inch) measures the open-cell density of our PPI filter foam sponge. Lower porosity (10–20 PPI) features larger pores for high dust-holding capacity and ultra-low pressure drop, ideal for HVAC pre-filtration and intake cotton replacements. Higher porosity (45–60 PPI) offers finer pore structures to capture smaller particulates (>=15 μm) in sensitive equipment enclosures. We can provide custom porosity samples based on your target filtration efficiency and airflow velocity.
Q2: Can your PPI filter foam sponge sheets and rolls be custom die-cut into non-standard shapes for OEM equipment?
A: Yes. As a direct reticulated PPI filter foam manufacturer, we offer precision CNC die-cutting and custom processing for OEM clients. We can fabricate custom PPI filter foam sponge sheets and continuous rolls in thicknesses ranging from 3mm to 50mm, maintaining tight dimensional tolerances (<=1mm) for a seamless, zero-leakage fit inside complex machinery housings.
Q3: How washable and durable is this reticulated open cell filter sponge in harsh industrial environments?
A: Engineered with 100% thermal reticulation and high-tensile polyether/polyester resins, our washable PPI sponge filter media resists crumbling, oil mists, solvents, and mild acids or alkalis (pH 5.0–8.0). It tolerates repeated water washing, compressed air blowing, and chemical cleaning with a typical operational lifespan of 3 to 5 years, drastically lowering long-term replacement budgets.
Q4: Do you supply fire-retardant or anti-static options for industrial safety compliance?
A: Absolutely. We offer functional additive treatments for our open cell PPI filter foam sponge, including UL94 compliant flame-retardant modifications (HF-1 / V-0 standards) and anti-static coatings. Every export batch meets RoHS and REACH compliance, making our filter media ready for international project bidding and strict safety audits.
Q5: What is the Minimum Order Quantity (MOQ) and lead time for wholesale open-cell polyurethane foam orders?
A: As a China PPI air filter foam supplier, we support global distributors and manufacturers with low MOQs for trial orders and flexible volume pricing for container loads. Standard specification sheets and rolls ship within 7–10 days, while custom die-cut orders typically take 10–15 business days following sample approval.
