tomotive filter paper is one of the main materials used in the production of automotive filters, also known as automotive filter paper, which includes air filter paper, engine oil filter paper, and fuel filter paper. It is a resin impregnated filter paper used in internal combustion engines such as automobiles, ships, and tractors, serving as the "lungs" of automotive engines to remove impurities in air, engine oil, and fuel, prevent wear and tear of engine components, and extend their service life. With the rapid development of the world automotive industry, resin impregnated paper filter cartthridges have been widely accepted and adopted by the automotive filter industry worldwide as a filtering material

Cured filter paper

The filter paper has not been hardened after being impregnated with phenolic resin, which can not satisfied the stiffness requirements of filter elements.

After being pleated the filter paper will be heated for 10-15 minuters at the 150ºC temperture.

Cured filter paper is widely used to produce oil and fuel filter paper element of heavy trucks, auto and cars.

Uncured filter paper

The uncured filter paper is impregnated with the mosplastic resin (generally is acrylic resin),and it needs little heating during production to guarantee the flexbility under room temperature.

Uncured filter paper is widely used to produce air filter elements of heavy trucks, auto and cars.

1 The filter paper can separate impurity particles from the liquid and extend engine and auto service life.

2 High filtration effenciency,98% filtration efficiency of *4um particles and 99% filtration efficiency of 6um particles.

3 Up to 800l/m2*s air permeability

4 Oil filter paper can withstand up to 600 kpa pressure

5 Up to 70mn*m high stiffness of cured filter paper.
