phenolicimpregnated
Phenolic-impregnated materials are composites in which a porous substrate such as paper, fabric, wood, or other textile-based materials is saturated with a phenolic resin and cured to form a rigid, thermosetting matrix. The term is commonly used in the context of electrical insulation and lightweight laminates, as well as in historical or specialty molding compounds.
Phenolic resins used for impregnation are typically phenol-formaldehyde systems, produced in novolac or resol formulations. These
The manufacturing process often involves impregnating the porous substrate under vacuum or controlled pressure to achieve
Limitations include brittleness and moisture sensitivity if not fully cured, as well as emissions concerns associated
