N352 Polyester imide laminate Details

This product is made by electrician alkali-free glass cloth dipped in polyester rubber resin by drying and hot pressing.

Appearance: The surface of the laminate is smooth and smooth, free of air bubbles, impurities and other obvious defects, allowing micro-scratches, the edges should be cut neatly, and the end faces must be free of delamination and cracks.

Color: deep red or custom

 

Performance:

1. High mechanical and dielectric properties
2. Good moisture resistance and processability
3. Heat resistance grade is H grade performance

 

Use:

Suitable for insulating structural parts of H-class electrical appliances, such as motor wedges, gaskets and outlet plates, dry transformer shims and terminal blocks.
