Phenolic Laminated Sheet (Hylem Sheet) – Electrical Grade Insulation Board (Eagle Insulation)

The Phenolic Laminated Sheet, also known as Hylem Sheet, is a high-strength, electrical-grade insulating material made by impregnating layers of paper or fabric with phenolic resin. Ideal for electrical, mechanical, and industrial applications, this sheet offers excellent thermal resistance, high dielectric strength, and mechanical durability. Commonly used in control panels, switchgear, transformer insulation, and other high-voltage installations, it is flame-retardant and machinable into various forms. Resistant to moisture, chemicals, and wear, this sheet provides long-term reliability and insulation in demanding environments.

Key Features:

• Made from phenolic resin-impregnated paper or fabric
• Excellent electrical insulation and high dielectric strength
• High thermal resistance (up to 130°C)
• Flame-retardant and moisture-resistant
• Machinable: can be drilled, cut, and shaped
• Ideal for electrical panels, busbar supports, insulators
• Also known as Hylem Sheet in industrial use
• Good mechanical strength and dimensional stability

Its Uses:

• Switchboards and electrical control panels
• Transformer insulation boards
• Busbar supports and partitions
• Industrial jigs, fixtures, and spacers
• Heat-resistant washers and terminal plates
