PAPER PHENOLIC LAMINATE AND RODS
Paper Phenolic Laminate sheets are made from layers of paper, impregnated with specifically formulated phenolic resins, bonded together under heat and pressure to produce a thermoset composite. Both paper and resins can be modified to change the finished properties of the final laminate. Offers enhanced mechanical, electrical, electrostatic dissipative or fire performance. The properties and cost-effectiveness of these products often make them insulators of choice in low/high-voltage, dry service electrical equipment.
