FDR / Garlam / Griflex / Triplex Slot Insulation Paper | Class E Electrical Insulation

The base layer is made from 100% sulfate wood pulp presspaper, providing fibrous strength, flexibility, and good mechanical durability. The outer polyester film layer enhances dielectric strength, surface smoothness, moisture resistance, and dimensional stability. This combination allows fish paper to retain flexibility even at low temperatures while offering dependable insulation performance.

FDR / Garlam / Griflex / Triplex insulation paper is widely used for slot insulation, phase insulation, turn-to-turn insulation, and liner insulation in Class E and Class B motors and electrical appliances. Available in multiple colors and customizable thicknesses, it is suitable for both standard production and specialized electrical insulation requirements.
