Performance Parameter Trends (2018–2024): Oil-Water Separation Filter Paper
2. Manufacturing Process of Oil-Water Separation Filter Paper
Oil-water separation filter paper is primarily composed of high-purity wood pulp—often combined with hydrophobic and oleophobic synthetic fibers for enhanced durability and selective separation. The process is subject to ISO, ANSI, and other international standards to ensure repeatable product quality and environmental compliance.
Below is an illustrated process flow:
- Pulping & Mixing : 100% virgin wood pulp, hydrophobic agents, and reinforcement fibers are uniformly blended.
- Sheet Formation : Slurry is converted to sheets, enabling fiber alignment for improved structural strength.
- Lamination : Specialty resins and microporous barrier layers are hot-pressed for multi-layer composites, yielding high-separation efficiency (via ISO 16889 protocols).
- CNC Cutting : Rolled filter paper is CNC-cut/sized for customer-specific dimensions and integrity.
- Quality Testing : ISO/TS 16332 emulsion separation, water breakthrough, and abrasion-resistance checks.
- Packing & Shipment : Output rolls/sheets pass stringent end-of-line inspection, moisture-proof packaging included.

Q2: Which industry standards do these filter papers comply with?
A: Laminated Filter Paper Fuel and Water Separation meets ISO 4020 (emulsified water separation), ISO/TS 16332 (particle retention), RoHS (environmental), and is compatible with most leading OEM specifications.
Q3: How is the air permeability parameter measured, and why is it important?
A: Air permeability (Gurley or Frazier method) in L/m²·s reflects ease of flow; higher values mean lower pressure-drop and energy saving—vital in high-flow fuel and water circuits.
Q4: What is the typical pore size for these papers, and how does it influence separation?
A: Nominal pore sizes are 15–25 µm, balancing water droplet coalescence (separation efficiency) with minimal fuel/air restriction (system efficiency).
Q5: What installation standards apply to laminated oil-water separation filter paper?
A: Our paper can be cut/pleated to match industrial and automotive filter element frames, using thermal bonding (not adhesives), meeting EN 1822/ISO 16889 construction guidelines.
Q6: What is the recommended replacement period or service interval?
A: For most automotive and industrial applications:
12–24 months or when ΔP exceeds 220–260 mbar (
Q7: Are there custom branding and OEM integration services?
A: Yes. Roll or sheet width, color banding, laser logo-marking, and test report traceability are available for all OEM/ODM customers.
