Laminated Filter Paper for Fuel Water Separation China Factory Suppliers
Our Laminated Filter Paper for Fuel and Water Separation is a high-performance composite media engineered for rigorous industrial and automotive filtration. By integrating PET spunbond nonwovens, PBT meltblown nonwoven fabric, and premium wood pulp filter paper through a precise ultrasonic spot welding process, this material provides an exceptional barrier against contaminants while ensuring efficient oil-water separation.
The strategic multi-layer construction optimizes both durability and filtration efficiency. The spunbond layer acts as a robust protective shield, the meltblown layer enhances dust-holding capacity and separation performance, and the wood pulp paper ensures the media meets all critical physical indicators and pleating requirements for seamless integration into final filtration systems.

The combination of PBT meltblown layers specifically designed for hydrophobicity and wood pulp for structural integrity creates a high-efficiency barrier that separates water from fuel more effectively than single-layer media.
Ultrasonic welding bonds the PET and PBT layers without using chemical adhesives, ensuring that no contaminants are introduced into the fuel stream and maintaining a consistent pore structure.
Yes, its high burst strength and precise max pore size (55±10 μm) make it ideal for automotive applications where protecting the fuel injection system from water and particulates is critical.
The wood pulp paper provides the necessary physical indicators and pleating stability, ensuring the filter maintains its geometry under pressure and contributes to the overall filtration performance.
While the standard is 250±20 g/sqm, we can adjust the composite layers to meet specific permeability or strength requirements based on your industrial application.
With a specification of 130±30 L/sqm.s at p=200pa, the material is engineered to provide high flow rates while ensuring a high capture rate of microscopic contaminants.
