FR1/XPC

Those materials are used in every-day devices that don’t require a large amount of modern technology. They are made of paper and phenol which are cheap and easy to build, but with poor resistance to heat (130°). The FR1 is still available on the market but is gradually being replaced by CEM1/FR3 and FR4 materials.
