Flexible Insulation Laminates

DMD – Dacron / Mylar / Dacron
Class F (150°C) Flexible Electrical Insulation

DMD is a high-performance flexible insulation material composed of two outer layers of non-woven Dacron® polyester and an inner layer of Mylar® polyester film. Designed for Class F electrical insulation systems, it delivers excellent dielectric strength, mechanical integrity, and heat resistance up to 150°C. Commonly used in slot and phase insulation for electric motors and transformers.

Key Features:

• Triple-layer laminate: Dacron / Mylar / Dacron for strength and durability
• Class F rating: Withstands continuous operating temperatures up to 150°C
• Flexible and tear-resistant: Easy to handle and apply
• Good dielectric performance: Suitable for low and medium voltage insulation systems

Typical Applications:

• Slot, phase, and liner insulation in electric motors
• Layer insulation in coils, transformers, and appliances
• Often paired with insulating varnishes and resins for enhanced thermal bonding
• Compatible with fibreglass and silicone sleeving in full motor rewind assemblies

Available Options:

• Supplied in full rolls (1 metre wide) or cut by the square metre 
• Standard lay-ups (outer / film / outer):

Format: outer layer / polyester film / outer layer

A dependable insulation laminate for applications requiring mechanical strength, flexibility, and Class F thermal performance.
