Phenolics are the result of polymerization between layers of paper, canvas, linen, or glass cloth impregnated with synthetic thermosetting resins. These industrial laminates are a popular alternative to acrylic, because of its high resistance to flexing.
The base material (paper, linen cotton, cotton canvas, or glass cloth) and resin combination used is dependent upon the intended application of the finished product. Physical strength, resiliency, ease and versatility of fabrication, and excellent electrical properties make phenolics useful as support components in a wide range of mechanical and electrical applications.
L/LE Cotton Linen Base Phenolic: Fine weave cotton linen and, like canvas phenolic, is known for it's mechanical properties. The finer weave allows better machinability than provided by the "C" and "CE" grades. The "LE" grade has better electrical properties than the "L" grade. This grade is not recommended for primary insulation. Linen-based phenolics with enhanced mechanical properties are available in a variety of sheet, rod, and tube sizes.
