Paper
| Product Description |
Kreca paper is made from Kreca Chop. Two types of Kreca Paper are available: Carbon paper, whose binder is carbon/graphite, and Natural paper, whose binder is organic. Since Carbon paper is not eroded by corrosive solutions, such as electrolyte, it is widely used for fuel cell electrodes. Its high wear and corrosion resistance properties make natural paper suitable for use as laminate material.
