Product Description
Class F DMD Soft Composite Fiberglass Mesh
Premium electrical insulation material specifically engineered for transformer applications with temperature ratings up to 155°C continuous and 180°C intermittent operation.
Product Overview
DMD (Dacron-Mylar-Dacron) soft composite fiberglass mesh cloth is a high-performance electrical insulation material designed for transformer winding and core insulation applications. This Class F rated material provides exceptional mechanical and electrical properties for demanding industrial environments.
Key Mechanical Properties
High tensile strength: Withstands significant stretching and pulling forces without breaking
Excellent flexibility: Ideal for winding around transformer cores without cracking
Superior tear resistance: Resists tearing and puncturing under mechanical stress
Good elasticity: Returns to original shape after deformation without damage
