Paper-based phenolic laminates (Hylam) for electrical insulation applications
Paper phenolic laminates, commonly known as Hylam, are manufactured by bonding multiple layers of kraft paper with phenolic resin under heat and pressure. The result is an economical laminate material with reliable electrical insulation properties.
These laminates are widely used in electrical equipment such as terminal boards, switchgear panels, and transformer barriers where high mechanical strength is not a primary requirement but consistent electrical insulation is essential.
Hylam sheets machine easily and are available in a variety of thicknesses and sheet sizes. They offer consistent dielectric performance at a competitive price, making them the preferred choice for general electrical insulation applications.
