LE PHENOLIC
Grade L Linen Phenolic uses a fine weave (less than 4 ounce/square yard) cotton fabric commonly called linen, combined with phenolic resin to provide a better machining material than grade C. It is commonly used for smaller and more intricate shapes than grade C. It is designated by MIL-I-24768/15 Type FBI and the NEMA grade is L.
