Frequently Asked Questions

Q: What is the primary application of Phenolic Resin Filter Paper?

It is primarily used for high-efficiency oil filtration, particularly in automotive engines and industrial machinery where high burst strength and thermal stability are required.

Q: How does the curing process improve the filter medium?

The curing process with phenolic resin increases the burst strength from 250kpa to 350kpa and enhances the stiffness, preventing the medium from collapsing under pressure.

Q: What is the average filtration efficiency (pore size) of this paper?

The average pore size is 55±5 um, with a maximum pore size of 80±5 um, ensuring effective capture of fine particulates in oil.

Q: Can this filter paper be used for air filtration?

While specifically optimized for oil filtration, the material's air permeability (350±30 l/m2sec) makes it adaptable for certain specialized industrial air filtration needs.

Q: Is this material resistant to high temperatures?

Yes, the use of a cured phenolic resin system provides significant thermal stability compared to non-cured cellulose papers, making it suitable for hot engine environments.

Q: What is the importance of the corrugation depth in this product?

The precise corrugation depth of 0.25±0.05 MM allows for consistent pleating, which maximizes the effective filtration surface area within a compact filter housing.
