Product Description

LINQCELL GDP210-MP is a 0.21mm thick carbon paper with a Microporous layer and PTFE. It is commonly used as a gas diffusion layer and electrode for fuel cells. Its through-plane resistivity is around 7.8 mΩcm2. This carbon paper is highly flexible and has excellent air permeability. It can compress down to 160um at 3.5MPa (350 N/cm2).

LINQCELL GDP210-MP is a close alternative to the discontinued Spectracarb 0850. There is also the option to make these with higher heat treatment as GDP210-MPS. This treatment reduces the resistivity and increases the compressibility of the sheets, for applications that require these properties.

Air Permeability
Air Permeability
The air permeability of a fabric is a measure of how well it allows the passage of air through it.
 93 cm3/s/cm2
Mechanical Properties
Tensile Strength (Thin Film)
Tensile Strength (Thin Film)
Tensile strength determines the resistance of a material to break under tension and it measures how much elongating load (or tensile stress) it can handle before fracture.

To make it simple, it measures how much force we have to apply when pulling apart a material before it breaks.

I see a checkered pattern on the sheet. Is this relevant to MD/XD?

The checkered pattern of  GDP210-MP is caused by the mesh pad that is used to apply the hydrophobic layer.  This has no effect on the products' strength or mechanical characteristics. Generally, the hydrophobic surface will face up, and the other side will not have this pattern.

Sometimes we tend to use a felt pad instead of a mesh, as with GPD-210-MPS, and the checkered pattern is not noticeable. So all in all these have nothing to do with MD/XD and is just a visual result of the methods used to make the surface Hydrophobic.

The only way to tell which side is which is this one:
