DMD Laminates (Dacron + Polyester Film + Non-woven Polyester)

DMD Laminates (Dacron® + Polyester Film + Non-Woven Polyester) are high-performance flexible insulation materials offering excellent dielectric strength, thermal stability, and mechanical durability. Widely used in motors, transformers, and electrical equipment, they are ideal for slot, phase, and interlayer insulation applications.

Overview

DMD laminates are flexible insulation materials made by bonding polyester film between layers of non-woven polyester fabric and curing under controlled conditions. These laminates are known for their good dielectric strength, flexibility, and thermal stability, making them suitable for Class B (130°C) insulation systems.

They offer reliable mechanical strength and are easy to handle, cut, and process, making them widely used in motor and transformer insulation where cost-effective performance is required.
